Step 1

Any GameObject that has a MeshFilter + MeshRenderer or SkinnedMeshRenderer can be painted.

Once the CwPaintableMesh component has been added, you can click the Analyze Mesh button to see if your mesh is suitable for painting.

Step 2

Next, you need to pick which textures you want to paint.

Your MeshRenderer or SkinnedMeshRenderer component has the Materials array, which usually has one material. Each material is rendered using a shader, and each shader has a list of textures that it uses. Most shaders have the Albedo/Color texture, but some more advanced shaders can have a Normal Map texture, Emission texture, etc.

You should now see the CwPaintableMeshTexture component added to your GameObject.

Inside this component, you can see the Slot setting. Next to this setting is a dropdown arrow button which you can click, and this allows you to pick from a list of all textures in your renderer.

For most objects, the default 0, _MainTex setting is all you need. But if you have multiple materials or need to do advanced painting you may need to change this. For example, to paint normal maps you may need to choose 0, _BumpMap or similar, the exact texture name depends on the shader/material.

The rest of the settings should be OK at their default values for now.

Step 3

Paint in 3D comes with many ways to paint objects.

One simple method is to make a new GameObject, and add the CwHitScreen and CwPaintDecal components. These components will automatically work together, allowing you to paint using the mouse (or your finger if you run it on a mobile device).

You can now adjust the CwPaintDecal settings to your liking. I recommend you at least change the Color or Texture, because the default paint color is white, and if you paint on a white texture then it may look like nothing is happening!

Once done, press play. You should now be able to click on your object in the Game window, and have the decal you paint on your object under the mouse.

For more advanced ways to paint I recommend you go through the demo scenes in the PaintIn3D/Examples folder and see how they're put together!

Presets

To save time, you can skip Step 1 & 2 by using the Presets system.

Paintable UV Maps

If your mesh is suitable for painting, it should look something like this.

As you can see, there are few overlapping triangles, few out of bounds triangles, few triangles with no UV, and the texture space is fairly well utilized.

Unsuitable UV Maps

If your mesh is NOT suitable for painting, it will look something like this.

As you can see, there are large areas of overlap in red, or many out of bounds triangles, or many triangles with no UV map.

In any of these scenarios, your mesh will need to be UV unwrapped before you can paint it.

Mesh Fixer

It's best to manually UV unwrap your meshes in your favorite 3D modeling software (e.g. Blender), because you will have full control over how it is unwrapped and can therefore give priority to certain areas and perhaps make better use of the texture space.

However, Paint in 3D comes with a tool to perform this UV unwrap for you.

To use it, click the Fix button at the top right of the Mesh Analysis window, and read the next tutorial section HERE.

Coord

This setting allows you to choose which UV channel/coordinate you want to fix. For most meshes this should be set to First.

Recenter UV

For a mesh to be paintable, the UV data must be within the standard 0..1 range on the X and Y axes. However, some assets or mesh workflows put the meshes in slightly different ranges like 1..2 or 2..3, typically across the X axis.

When the UVs are recentered, it detects this scenario, and shifts the UVs to the typical 0..1 range.

Generate UV

If you enable this setting, then your mesh will have entirely new UV data generated.

Fix Seams

If you enable this setting, then the UV island edges of your mesh will be extended so they can be painted without seams appearing.

Generate

Once you're happy with your mesh fixer settings, you can click the Generate button.

This will make duplicates of all meshes in the Meshes list, process them based on your settings, and then save them as child assets of the mesh fixer.

Next to your mesh, you can click the Analyze New button to see what the new fixed UV map looks like.

Swap Meshes

If your scene contains CwPaintableMesh components that still use the old non-fixed meshes, then they will show up at the bottom of the mesh fixer under the SWAP MESHES list, allowing you to quickly update them.

Remap Texture

If you enable GenerateUV, then your meshes will have their UV data completely replaced with an entirely new layout.

This is fine if your meshes will then be painted from scratch. However, if your meshes originally had a texture, then those textures must be remapped to the new UV data.

To remap them, simply drag and drop your textures into the Remap Texture field one at a time. This will reveal a list of meshes you can use for the remapping, and once chosen you will be prompted to save the texture.

This remapping feature is very useful with low-poly style meshes, which are typically colored using an atlas style color palette, where the UV data for each triangle is flattened to a point on a specific color.

Does Paint in 3D come with shaders that use the second UV channel?

Yes, Paint in 3D comes with several shaders designed to solve this issue.

If you want to keep your original shader/material that uses the first UV channel, then you can use the Paint in 3D / Overlay shader on top of your base material. Paint in 3D already comes with a pre-configured material called Overlay (Second UV Coord), which you can add on top of your base material. Keep in mind you will now be painting the second material (index 1), so you must update your CwPaintableMeshTexture component settings to target the second material slot index (1).

This technique is demonstrated in the UV Requirements / Automatic Overlay demo scene.

If you don't mind replacing your original shader/material, then the Paint in 3D / Solid shader can be used instead. This shader uses the first UV channel for base textures, and then allows you to override the albedo/opacity/smoothness/etc using secondary textures that use the second UV channel.

This technique is demonstrated in the UV Requirements / Automatic Secondary demo scene.

Can I use the second UV channel with the Standard shader?

Kind of. Using the following steps you can get it working using the detail texture. Just keep in mind this isn't the best solution, because it doesn't replace the albedo exactly.

How can I use the second UV channel with a different shader?

Most shaders only the first UV channel, so you will need to make an alternative shader that uses the second.

For example, instead of using uv_MainTex you use uv2_MainTex, or instead of using texcoord0 : TEXCOORD0, you use texcoord1 : TEXCOORD1.

Paint in 3D comes with a range of shaders that allow you to specify the UV channel used (e.g. PaintIn3D/Opaque).

Step 1

Select the Window/CW/Paintable Objects menu option.

This will open the Paintable Objects window.

Step 2

You can now select some GameObjects in the Scene or Hierarchy window.

Any GameObject or child GameObject you select that has a MeshFilter + MeshRenderer or SkinnedMeshRenderer will appear as a list in this window.

Step 3

Next to each GameObject will be the Make Paintable button.

If you click this, it will list all possible presets for this Renderer and Material's Shader type.

You can then choose one.

Custom Shader

Paint in 3D comes with presets for most of Unity's built-in shaders. However, if you've made your own shaders, or you have another asset with custom shaders, then you will have to add them to an existing preset.

All presets can be found in the Plugins/CW/PaintIn3D/Extras/Presets folder.

For example, the Basic - AA preset allows you to paint the _MainTex, which is usually the albedo (+ optional Alpha/Opacity). If you want to add your custom shader to this preset, then you can add it to the Shader Paths list.

If you're unsure what your shader is called, or want to add multiple shaders to this preset, then you can click the Find Shaders button, which will find all shaders in the current project that have all textures used by the preset (in this case of the Basic - AA preset, all shaders with _MainTex will be listed).

Custom Preset

If the presets that come with Paint in 3D aren't suitable for your project, then feel free to right click in the Project window, and select the Create/CW/Paint in 3D/Preset option.

This will add a new prefab to your project with the CwPreset, MeshFilter, MeshRenderer, and CwPaintableMesh components attached.

You must then set the ShaderPaths to include your shader, add all the CwPaintableMeshTexture components you want for this preset, and configure their Slot settings.

You can now use this preset from the Make Paintable button in the Paintable Objects window.

How do we fix them?

To fix these UV seams, Paint in 3D comes with a tool that can convert a normal mesh with UV seams into a fixed mesh without UV seams.

To access the tool, select any mesh in your project, click the context menu icon (⋮ button) at the top right, and select Fix Mesh (Paint in 3D).

This creates a seam fixer in your project, and automatically sets the Source mesh to the one you picked.

You can now press the Generate button to generate the fixed mesh.

If it was successful, you should see something like this in your Scene window:

Where the green lines are the original seams, and the blue lines are the new fixed seams. The blue lines should be outside of your original green lines. If your blue lines are overlapping then try reducing the Border setting a little, or the Threshold setting.

How do we use the fixed mesh?

The generated mesh will be placed as a child of the seam fixer in your Project window.

To use it, just drag and drop it from here into your MeshFilter or SkinnedMeshRenderer that uses this mesh.

Auto Seam Fixer

If the above steps seem too tedious for you, then you can let Paint in 3D automatically do the seam fixing for you.

Your mesh will now be auto seam fixed just before you paint it for the first time.

If either of these caveats is an issue, then I recommend you follow the previous section and manually seam fix the mesh.

UndoRedo Setting

The first step is to select your CwPaintableMeshTexture components, and enable the UndoRedo setting.

If you're painting animated objects then you should set this to FullTextureCopy, but for most scenarios you can use LocalCommandCopy.

If you use the FullTextureCopy state mode then you must also set the State Limit setting. A value of 10 means you can undo paint operations 10 times, and then redo them 10 times. If you paint 11 times with this setting then your initial paint state will be deleted, and you will only be able to undo 10 times to your first paint operation.

You can read the CwPaintableMeshTexture documentation for more details.

Store States

The next step is to find your painting components, and enable the Store States setting.

This setting will automatically call the StoreState method on each CwPaintableMeshTexture in your scene, letting Paint in 3D know that you're about to paint on them.

For example, the CwHitScreen component has the StoreStates setting, as well as CwToggleParticles, and CwTapThrow.

Buttons

Finally, you can add the CwUndoAll and CwRedoAll components to your UI elements, and they will automatically be set up so when you click them they perform an undo or redo operation.

And that's it, your game should now have Undo & Redo paint functionality!

Memory Usage

Keep in mind that when using the FullTextureCopy mode, each undo/redo state is stored as a full texture state. This means that if your texture is 1024x1024 using the RGBA32 format, then each undo/redo state will consume 1024x1024x4 bytes of memory, or 4 megabytes.

If your game requires a lot of undo states and you want to reduce memory usage, then you should use the LocalCommandCopy mode instead, which will store a list of all paint commands (e.g. decal texture + paint orientation). This approach can reduce memory usage a lot, and it allows unlimited undo levels, but performing an undo requires rebuilding the texture from scratch, which can be slow if you have a lot of undo states. It also may not work correctly if your mesh is animated, because the paint will apply to different areas if your mesh has changed.

Manual Undo & Redo

The undo & redo functionality listed above works well for most games, but it's not suitable for all scenarios. To get full control you can manage it yourself using the following methods in the CwPaintableMeshTexture class:

Call StoreState before you apply paint to your objects.

Call Undo/Redo after, when you want to undo or redo.

These methods can also be accessed from the CwPaintableMeshTexture inspector context menu (⋮ button at top right), so you can test it from the editor.

Alpha Blend

This blend mode increases the alpha channel of your texture, and blends the RGB channels of your texture toward the color of your paint, based on the opacity of your paint.

Alpha Blend Inverse

This blend mode works similar to Alpha Blend, but it applies the blending in reverse.

This allows you to paint 'behind' the current painted areas, or fill them in.

Alpha Blend RGB

This blend mode works similar to Alpha Blend, but the alpha channel is not modified. This is ideal when you want to paint on only the solid parts of an already transparent texture.

Additive

This blend mode works by increasing the RGBA values of your texture based on the paint color.

Additive Soft

This blend mode works similar to Additive, but the strength of the blending fades based on how bright the texture already is.

Subtractive

This works by decreasing the RGBA values of your texture based on the paint color.

Subtractive Soft

This blend mode works similar to Subtractive, but the strength of the blending fades based on how dark the texture already is.

Replace

This blending mode works like Alpha Blend, but the alpha channel of the texture will transition toward the paint alpha channel value, rather than just increase. In effect, this blends all channels toward the paint color at the same rate.

This is useful for painting advanced textures (e.g PBR), where you want to paint a specific alpha channel value.

Replace Original

This blending mode works similar to Replace, but instead of transitioning to the paint color, the paint color will be based on the original color of the texture.

This color is defined by the CwPaintableMeshTexture component's Texture and Color settings.

Replace Custom

This blending mode works similar to Replace Original, but instead of transitioning to the original texture color, you can specify a custom texture and color to transition to.

Multiply Inverse RGB

This blend mode allows you to darken your texture based on the paint color.

To make it easier to use, the blending is inversed. This means your decal should be white where you want the color to be multiplied, and black where you want no change.

Blur

This blend mode allows you to blur your texture based on the paint opacity.

Normal Blend

This blend mode allows you to paint a normal map with another, and both normal maps will combine together.

Normal Replace

This blend mode allows you to paint a normal map on top of another, and the original normal map will be replaced by the new one.

Flow

This blend mode allows you to move the pixels in the texture you're painting. The direction and distance the pixels will move is based on the normal map you specify.

Colliders

Normal non-skinned meshes are usually static, so you can just add a MeshCollider. However, skinned meshes usually bend and deform such that you cannot use a MeshCollider, because as soon as it animates, the collider surface will not match the visual mesh, which causes the paint to apply to the wrong area.

While the collider doesn't have to match the visual mesh, it needs to be close enough relative to the size/radius of your paint tool (e.g. CwPaintDecal's Radius & Scale settings). If you have a complex skinned mesh, this usually means you must add many colliders to your object (e.g. BoxColliders and CapsuleColliders, perhaps one per bone).

However, if your game doesn't require precise painting (e.g. bullet wounds only), then there is one alternative strategy that is simpler to configure that is shown in the "PaintIn3D/Examples/Zombie Blood" demo scene. In this scene, the skinned zombie mesh is given one large BoxCollider, that encapsulates the whole zombie animation cycle. The CwHitScreen component's RotateTo setting is set to Normal, and RotateTo/Direction is set to RayDirection. The CwPaintDecal component's Scale.z setting is then set to 15 (the exact value depends on the size of the skinned mesh). With this configuration, the paint is aligned to and stretched along the hit direction, so it goes through the skinned mesh.

Include Scale

Inside the CwPaintableMesh component is the IncludeScale setting. Depending on your skinned mesh, you may need to enable this setting for the painting to work.

I wasn't able to identify exactly when this setting needs to be enabled or disabled, so it can't be automatically set. I think it has something to do with the software used to export the mesh, or the export settings, so for now you must manually try toggling this if you find your mesh can't be painted even if every other setting looks correct.

Overlap Points

When using connected hits, the connected lines are drawn separately, which causes the overlapping corners to receive double the paint. This is an issue with semi-transparent painting, because they will appear stronger than the main line body.

To fix this, you must enable the Advanced / Clip Connected setting, which eliminates this issue in most scenarios.

Texture Resolution

The easiest way to optimize painting performance is to reduce the size of your CwPaintableMeshTexture. If you halve the width & height of your texture, then there are now only 1/4 of the pixels being painted, which means your paint will apply up to 4x faster.

I recommend you reduce the texture resolution as much as possible, until you find the perfect balance between performance and visual quality.

Paint Framerate

Another easy way to optimize your painting is to paint less often.

For example, the CwHitScreen component has the Interval setting, which allows you to choose the pixel distance between each paint hit. If you set this to 3 pixels and move your mouse/finger 300 pixels in one frame, then this will result in your scene being painted 100 times. If you increase this to 6 pixels, then it will result in the scene being painted 50 times, or a 2x optimization. You can also set the Frequency to OnceEveryFrame, which will paint the scene no more than once per frame.

For example, the CwHitParticles component by default paints every time a particle hits something. This can be optimized using the Advanced / Skip setting, which allows you to paint once every n times.

Split Meshes

If your object has a large texture and you cannot reduce its resolution, then you can still optimize the painting without a loss in detail. This is done by splitting your mesh up into smaller parts, and setting them up as separate objects. If done correctly, when you paint your object only a small area of it will be painted, and thus less pixels will be processed overall.

The easiest example of this is painting a large wall. Instead of having one wall mesh, you can split it up into a grid of smaller sections. If done correctly you will still have the same overall texture resolution, but when painting you will only every paint a small number of meshes in this grid, and thus your painting performance will be greatly improved.

_MainTex & URP/HDRP

If you're using URP or HDRP, then you may notice painting _MainTex (Albedo) doesn't work, even though it shows up in the inspector list.

This is because these shaders seem to have a 'fake' _MainTex slot that doesn't do anything.

To fix this, you must instead paint the _BaseMap, which is the 'real' albedo texture.

Galaxy S6 / Mali-T760MP8

This device can incorrectly paint on Android 7 with the OpenGL ES3 graphics API. Previously painted pixels are observed to randomly become transparent and otherwise change.

If you need to support this device:

This should allow you to paint properly again.

VR Tools

While the painting features can work with any VR asset/toolkit, the Paint in 3D VR examples are only configured to work with Unity's legacy XR system.

Better Shaders

This compatibility was made possible using the Better Shaders system (not required).

The Better Shaders asset generates multiple variants of each shader ahead of time, so even if you don't have this asset, you will still be able to have full render pipeline compatibility with Paint in 3D.

BetterShaders (and therefore this asset) currently supports:

Standard Rendering Pipeline from Unity 2019 on

URP7.x in Unity 2019.3LTS

URP10.x in Unity 2020.3LTS

URP12.x in Unity 2021.2

URP14.x in Unity 2022.2->2022.3LTS

HDRP7.x in Unity 2019.3LTS

HDRP10.x in Unity 2020.3LTS

HDRP12.x in Unity 2021.3LTS

HDRP14.x in Unity 2022.2->2022.3LTS

Support for newer versions will appear when it does in this asset.

Lights

Each rendering pipeline handles lighting differently. To make the scenes look consistent, each light has the CwLight component attached to it, which overrides the light intensity for each pipeline.

If you don't like this behavior then you can set the values (for example IntensityInHDRP) to -1.

Opaque Texture (URP only)

If you want to use the SgtBlackHole feature, then you must enable the Opaque Texture setting in your pipeline settings asset.

Volume (HDRP only)

To make HDRP compatibility seamless, each demo scene contains the CwSceneManager GameObject, which adds the Volume component in HDRP.

This volume will adjust the scene exposure, disable the visual environment, and disable fog. These are all done to make the scenes look consistent with the other rendering pipelines. If you want to adjust these settings yourself then delete this GameObject, and create your own volume.

However, for your own scenes you may want to remove this volume component and use your own exposure settings.

Paint Hits

Paint hits are the high-level data used to paint your scene (e.g. the CwHitScreen component sends hit data to components like CwPaintDecal). Depending on the paint hit type, this just stores the world space position, rotation, seed, and other basic data.

This is the easiest data to send, but since the data is handled in world space and applied to everything in the scene, it's not suitable for moving objects.

To listen for paint hits you can create a new component and add it to the GameObject that has your CwHit___ component. You can then implement any of the IHit___ interfaces, to get specific hit data. For example, the CwHitScreen component can send point and line hit data, so you can implement the IHitPoint and IHitLine interfaces.

When a hit occurs, the HandleHitPoint and HandleHitLine and methods from these interfaces will be invoked. You can then store the given parameters to a file, or send it over the network.

Once this data is loaded/received, you can then broadcast it again using code like this:

// Loop through all components that implement IHitPoint
foreach (var hitPoint in GetComponentsInChildren())
{
	// Ignore this one so we don't recursively paint
	if ((Object)hitPoint != this)
	{
		// Submit the hit point
		hitPoint.HandleHitPoint(preview, priority, pressure, seed, position, rotation);
	}
}

You can see the CwPaintMultiplayer.cs code for an example of this.

Paint Commands

Paint commands are the low-level data used to paint each individual paintable texture. These store everything about the paint that was applied (e.g. texture references), so it's not as simple to serialize it all.

To allow for de/serialization of this data, you must first provide unique hash codes to the CwPaintableMeshAtlas, CwPaintableMesh, and CwPaintableMeshTexture components. This is done via the Advanced / Hash setting.

In addition to these hashes, you must provide hashes for all textures used by your paint commands. For example, if you use decal painting then the decal texture must have a hash.

Since the Texture class is made by Unity and can't be modified, you must assign a hash to a texture using the CwTextureHash component. You can add this component to your scene, assign the texture, and assign a hash code.

You can now listen for paint commands using the static CwPaintableTexture.OnAddCommandGlobal event, or the instance OnAddCommand event. These events will give you every paint command for a specific paintable texture.

The paint command can then be stored or sent over the network using JsonUtility serialization, or similar.

Once this data is loaded/received, you can apply it using your paintable texture component's AddCommand() method.

You can see the CwCommandSerialization.cs code for an example of this.

Basic Setup

This shows you how the Spaceship GameObject can be made paintable. This is done by adding the CwPaintableMesh and CwPaintableMeshTexture components. You can then paint the spaceship using the mouse/finger with the Paint GameObject, which has the CwHitScreen and CwPaintSphere components. Keep in mind that CwHitScreen uses raycasts, so your mesh must have a collider to work.

Seam Fixer

This shows you how to remove painting seams from your mesh using the Mesh Fixer tool. Seams are caused by gaps/islands in the mesh UV data, which are usually present at the edges of complex meshes. To use the mesh fixer, simply click the context menu button (⋮ icon) at the top right of your mesh inspector window. You can then select Fix Mesh (Paint in 3D), adjust the settings, and click Generate. You can double click the Spaceship GameObject's MeshFilter.Mesh setting to see it in action.

Auto Seam Fix

This shows you how to automatically fix seams in your mesh without using the Seam Fixer tool. This is done by changing the CwPaintableMesh component''s Advanced / UseMesh setting to AutoSeamFix. Keep in mind this mode doesn''t give you control over the seam fix settings (the defaults should be suitable for most meshes). Also keep in mind there will be a small performance hit the first time you paint your object when its seam fixed mesh is generated.

Unsuitable UV

This shows you what happens when you paint a mesh that isn''t suitable for painting. For a mesh to be paintable, it shouldn''t have overlapping UV, or UV areas that exceed the 0..1 range (e.g. tiling). Notice the paint appears in unexpected areas on this mesh, because it contains both tiling UV, and overlapping areas.

Cube

This shows you how painting meshes with overlapping UV data can cause unexpected results. The left shows you what painting the standard Unity Cube mesh looks like, and the right shows what painting the Separated Cube mesh that comes with Paint in 3D looks like.

Cylinder

This shows you how painting the standard Unity Cylinder mesh can give unexpected results, and how the Separated Cylinder mesh that comes with Paint in 3D can avoid these issues.

Auto UV

This shows you how a mesh with UV data unsuitable for painting can still be painted. This is done by enabling the Generate Lightmap UVs setting in the mesh import settings. This setting will generate new UV data in the second UV channel/coord, which can be used by custom shaders. The Paint in 3D / Solid shader has this feature if you enable the Use Second UV setting. If you use this configuration then make sure the CwPaintableMeshTexture.Coord is set to the Second UV channel.

Overlay

This shows you how the Unsuitable UV demo scene can be modified to allow correct painting on top. This is done by generating mesh data for the second UV channel/coord as seen in the Auto UV demo scene, and using a second transparent material layer on top of the base material. This second material uses the Paint in 3D / Overlay shader, which allows you to paint on top of the base material using the second UV channel. If you use this configuration then make sure the CwPaintableMeshTexture.Coord is set to the Second UV channel.

Override

This shows you an alternative way to paint objects using secondary UV data. The overlay approach requires multiple materials, which may not be suitable for your project. In this scenario, you can use a shader that is specifically designed to allow you to paint on both the first and second UV channels. The P3D Solid shader has the basic albedo/metallic/etc textures that use the first UV channel, but you can also override these using secondary albedo/metallic/etc textures that use the second UV channel. This is done by painting the _AlbedoTex/_MetallicTex/etc, which will override the base texture based on the opacity of the secondary paint. Keep in mind this shader requires you to paint the override textures using the Premultiplied blending mode.

Base Color

This shows you what happens when you paint objects that have materials with different color settings (top row). Notice how the color tint also applies to the paint, because the material color is multiplied with the painted texture color. To make the painted color apply without tinting you can set the material color to white, and instead change the CwPaintableMeshTexture.Color setting to the base color you want (middle row). You can also set the material color to white, and instead change the default texture (e.g. Albedo texture) to the color you want (bottom row).

Dots

This shows you how decreasing the CwPaintSphere.Radius setting and/or increasing the CwHitScreen.Interval setting allows you to draw dotted lines.

Connect Hits

This shows you how the CwHitScreen component''s Advanced / ConnectHits setting can be enabled, allowing paint dots to be joined together. A similar result can also be achieved using a lower Interval setting, but that has a performance penalty.

Clear Texture

This shows you how the CwButtonClearAll component can be added to a UI element, which makes it clear the paint of all textures in your scene. This also shows you how you can clear the texture of a specific texture by connecting the OnClick event to the CwPaintableMeshTexture.Clear method.

Isolate Tools

This shows you how the CwButtonIsolate component can be added to UI elements. This turns them into buttons that can enable a GameObject, and disable its siblings. This allows you to switch between different painting tools.

Tiled Painting

This shows you how the CwPaintSphere component''s Advanced / Tile settings can be used to paint seamless textures across your objects. This is done using triplanar mapping.

Blur Painting

This shows you how the paint component''s BlendMode setting can be changed to Blur. This blending mode blurs the pixels of the paintable texture.

Mask

This shows you how to prevent the Blur blending mode from causing the pixels outside the edges of your mesh UV islands from ''bleeding'' into your main texture. This is done by setting the CwPaintableMeshTexture component''s Advanced / LocalMask texture. This texture can be created using Paint in 3D if you begin with a black paintable texture, paint it white, and then export the painted texture via the main Paint in 3D window.

Generate

This shows you how the CwPaintableMeshTexture component''s Advanced / LocalMask texture can be automatically generated with a mask suitable for use with the Blur blending mode. This is done by adding the CwGenerateMask component alongside your CwPaintableMeshTexture component, and setting its Mesh setting to be the non-seam-fixed (original) version of your mesh. Automatically generating the mask like this means your build size doesn''t increase.

Decal

This shows you how the CwHitScreen and CwPaintDecal components can be combined to paint decals. Decals allow you to paint a custom texture on an object at a specific location. The CwPaintDecal settings give you control over the angle, size, opacity, etc.

Wrapping

This shows you how the CwPaintDecal component''s Wrapping setting can be used to control how the decal is applied to curved surfaces. When set to 0, the decal is applied using planar projection without any wrapping. When set to 1 the decal is wrapped around curved surfaces.

UV

This shows you how the CwHitScreen component''s Emit setting can be set to PointsOnUV, allowing you to apply decals directly to your paintable texture in UV space. This is useful when painting complex curved surfaces, because the texture can apply without distortion if your mesh is suitably UV mapped. Keep in mind this mode requires a non-convex MeshCollider for UV data, and for your objects to all have consistent texel sizes. Keep in mind this mode does not support painting between UV seams, and you may get paint bleeding if your UV islands are too close together. This scene also makes use of the Group setting (works like Layers) to avoid cross painting.

Normal

This shows you how the CwHitScreen component''s Advanced / Normal settings can be used to control the visibility of the decal based on to the the angle between the decal and the surface being painted. This allows you to enable or disable painting of steep angles, behind surfaces, etc.

Normal Front

This shows you how the CwPaintDecal component''s Advanced / NormalFront setting can be used to force paint to only appear on surfaces that have a surface normal (direction) similar to the surface normal of the hit point (mouse point).

Normal Fade

This shows you how the CwPaintDecal component''s Advanced / NormalFade setting can be used to control the sharpness of the normal cut-off transition.

Settings

This shows you how the CwPaintDecal settings can be modified from UI buttons by calling the various functions like IncrementAngle, FlipVertical, etc.

Mirror

This shows you how the Mirror GameObject has the CwCloneMirror component attached. This automatically mirrors all paint across a 3D plane defined by its Transform position and rotation. If you select the Mirror GameObject then you can see a preview of the mirror plane in the Scene view.

Flip

This shows you how the Mirrored Painting demo scene can be modified to prevent decals from appearing backwards when mirrored. This is done by enabling the CwCloneMirror.Flip setting, which makes the decals appear the same on both sides.

Multiple

This shows you how mirrors can combine together, creating interesting symmetries.

Collision Painting

This shows you how to apply paint when a Rigidbody collides with something. The CwTapThrow component can be used to spawn and throw the Ball prefab when you click or tap the screen. The ball then paints the spaceship on impact using the CwHitCollisions and CwPaintDecal components.

Destroyer

This shows you how to automatically destroy a GameObject itself when it hits something. This is done by adding the CwDestroyer component alongside the CwHitCollisions component.

Spawner

This shows you how to spawn an explosion effect when a Rigidbody hits something. This is done by adding the CwSpawner component alongside the CwHitCollisions component. The spawned prefab contains a ParticleSystem, and uses the CwDestroyAfterTime component to destroy itself.

Between Painting

This shows you how the CwHitBetween component can be used to paint between two Transform points. The CwHitBetween.Line can be used to visualize the current beam, and the CwHitBetween.Point setting can be used to vislize the hit point with particles.

Center Screen

This shows you how to paint everything at the center of the screen directly in front of the camera, like a laser eye beam. This is done using the CwHitBetween component, which is set to hit between the Main Camera Transform, and the In Front Of Camera Transform, which is a child GameObject placed in front. This will then automatically call CwPaintSphere on the first hit point it finds between these two points, and paint them red. The camera can then be rotated using the CwPitchYaw component.

Through Points

This shows you how the CwHitThrough component can be used to paint trhough two Transform points. The CwHitThrough.Line setting can be used to visualize the current beam. Unlike CwHitBetween, this component paints all surfaces between the two points.

Particle Painting

This shows you how the CwHitParticles component can be added to your ParticleSystem GameObjects. This allows you to paint with components like CwPaintSphere when particles hit objects in the scene. Keep in mind you must enable collision in your particle system for this to work.

Optimization

This shows you how particle painting can be greatly optimized. By default, the CwHitParticles component paints once per particle collision. However, this can be incredibly slow if you emit too many particles. To optimize this, you can use the CwHitParticles component's Advanced / Skip setting, which allows you to paint once every 'Skip' particles. In this scene Skip = 10, which means for every particle collision that would result in a call to CwPaintSphere, 9 calls are skipped.

Nearby Painting

This shows you how the CwHitNearby and CwPaintSphere components can be combined to paint any surfaces within the specified sphere shape.

Throw

This shows you how the CwTapThrow component can spawn and throw the Ball prefab. This prefab has the CwHitNearby component, which can paint surfaces near the current Transform position. This effect can be used to create fireballs that pass through objects, and paint them on the way.

Auto Save Load

This shows you how the CwPaintableMeshTexture.SaveName setting can be used to enable automatic save/load. Paint something, then run the scene again to see it in action. Keep in mind these save names should be unique, so using the same name with multiple prefabs may not work as expected.

Undo Redo

This shows you how the CwPaintableMeshTexture.UndoRedo setting can be used to store undo and redo states. You can then add the CwButtonUndoAll and CwButtonRedoAll components to UI elements to cycle through them. Keep in mind storing of states requires the StoreStates setting to be enabled, this is on components like CwHitScreen.

Paint Modifiers

This shows you how the paint settings can be randomly adjusted before the paint is applied. This is done by clicking the Add Modifier button inside the paint component (e.g. CwPaintDecal), and selecting a value to modify (e.g. Angle), and then the type of modification (e.g. Random). Keep in mind these modifiers can be combined together to make even more interesting results.

Gradually Fade

This shows you how to gradually fade a texture back to its original state after you paint it. This is done using the CwGraduallyFade component, and dragging and dropping the texture you want to have fade into the PaintableTexture setting. You can then set the BlendMode setting to ReplaceOriginal, and it will gradually fade to its original state as defined by the CwPaintableMeshTexture component''s Texture and Color settings.

Blur

This shows you how the Gradually Fade demo scene can be modified to blur the texture over time.

Normal

This shows you how the Gradually Fade demo scene can be modified to fade a normal map to its original state. This is done by using the Normal Replace blending mode and the DefaultNormal texture. Keep in mind the ReplaceOriginal blending mode can''t be used with normal maps, because the original texture and color are converted into normal maps, and this would cause them to be replaced by their non-converted state.

Painting Holes

This shows you how to paint holes in your paintable objects. This is done using the Subtractive blending mode, which allows you to reduce the alpha/opacity of the pixels in your texture. Keep in mind this requires you to use a shader/material that supports transparency, like the P3d Solid one used here. Keep in mind the underlying mesh still remains, so you can''t paint through the holes you create.

Replace Painting

This shows you how the CwPaintReplace component can be used to replace every pixel in the currently painting texture. Keep in mind the GameObject with the CwPaintableMeshTexture must have a collider for this to work, and CwHitScreen.Emit must be set to PointsOnUV.

Fill Painting

This shows you how the CwPaintFill component can be used to blend every pixel in the painted texture. This allows you to gradually change it, rather than instantly like CwPaintReplace does. Keep in mind the GameObject with the CwPaintableMeshTexture must have a collider for this to work, and CwHitScreen.Emit must be set to PointsOnUV.

Paint From Invisible

This shows you how to paint an object in from an invisible state. This is done by changing the CwPaintableMeshTexture.Color setting''s alpha/opacity value to 0, which causes the texture to initialize as invisible. You can then reveal the object by painting the alpha/opacity back in, which is automatically done when using the Alpha Blend blending mode. Keep in mind this requires you to use a transparent material/shader like the Paint in 3D / Solid one used here.

Reveal Original

This shows you how a textured mesh can be hidden, and then revealed by painting on it. This is done by changing the CwPaintableMeshTexture.Color alpha/opacity value to 0. The texture can then be revealed by painting with the Additive blending mode, with a color of RGBA 0,0,0,1. Keep in mind this requires your mesh to use a transparent (e.g. cutout) shader/material.

Glass Painting

This shows you how to paint on top of a transparent material. This is done using the Alpha Blend blending mode. Notice how the erase tool erases both the paint, and the original dirt.

Override

This shows you how the Glass Painting demo scene can be modified so the paint is applied to secondary albedo and opacity textures that override the base values. Notice how the erase tool only erases the new paint, and keeps the original dirt. This technique also allows you to paint at a lower resolution, but keep the original higher resolution texture, allowing you to optimize performance. Keep in mind this configuration requires you to use a special mater/shader designed to override the base texture values (the Paint in 3D / Alpha shader is used here). Keep in mind the override textures use premultiplied alpha, so you must set your paint tools to use the Premultiplied blending mode (though erasing can use the subtractive blending mode).

Channel Counter

This shows you how the CwChannelCounter component can be used to count the total pixels in the specified CwPaintableMeshTexture that exceed the threshold value in each R/G/B/A channel. The CwChannelCounterText component can then be used to display these in the UI.

Percentage

This shows you how the Channel Counter demo scene can be modified to accurately display how much of a mesh you have painted. This is done by setting the Spaceship GameObject\u2019s CwChannelCounter.Mesh setting to the original non-seam-fixed mesh. The paint percentage can then be displayed using the CwChannelCounterText and CwChannelCounterFill components. To make the paint work with any color this spaceship paint uses a second layer on top, similar to the Paint On Top demo scene.

Color Counter

This shows you how the CwColorCounter component can be used to count the total pixels in the specified CwPaintableMeshTexture that are within the threshold color of a CwColor. The CwColorCounterText component can then be used to display these in the UI.

Change Counter

This shows you how the CwChangeCounter component can be used to count how many pixels in the specified texture are different to a reference state. The reference state can be set using the CwChangeCounter component''s Texture and Color settings.

Paint Remaining

This shows you how the Alpha Blend Inverse blending mode can be used to paint transparent areas of your texture. This gives the effect of painting undernearth your existing paint.

Replace Original

This shows you how the Replace Original blending mode can be used to paint your object back to its original state based on the CwPaintableMeshTexture component''s Texture and Color settings.

Replace Custom

This shows you how the Replace Custom blending mode can be used. This works similar to Replace Revert, but you can specify custom Texture and Color values per paint tool.

Dynamic Decal

This shows you how to paint decals with dynamically changing content. This is done using a RenderTexture, making a second camera, and changing its TargetTexture setting to the RenderTexture. Keep in mind you must correctly set up your layers and Camera.CullingMask values to keep each camera isolated. Also keep in mind dynamic decals can''t be undone using the CwPaintableMeshTexture.State = LocalCommandCopy setting.

Live Painting

This shows you how to create live paint that can be repositioned in game. This is done using the CwHitNearby component with the Preview setting enabled. You can control the draw order of these decals using the Priority setting.

Apply

This shows you how live paint can be applied to your objects when you press a button. This is done by linking the button's OnClick event to the CwHitNearby component's ManuallyHitNow function.

Translate

This shows you how the CwTranslate component can be used to move a live decal around the scene using UI button events that call the CwTranslate.TranslateX/Y/Z functions.

LOD Painting

This shows you how to optimize painting speed using different LOD meshes for visuals and painting. The Knot_High GameObject is used to render the high poly visual mesh. The Knot_Low GameObject is used for the low poly MeshCollider, and for painting. To make the paint apply on the high poly mesh, the CwPaintableMesh.OtherRenderers list contains the Knot_High MeshRenderer.

Atlas Painting

This shows you how to paint multiple separate objects that share the same texture. This is done by setting up one paintable object normally, and then dragging and dropping the other objects into the CwPaintableMesh component's Advanced / OtherRenderers list. You must then add the CwPaintableMeshAtlas component to the other objects, and drag and drop the first object into the CwPaintableMeshAtlas.Parent setting.

Fill Painting

This shows you how to paint filled in polygon shapes. This is done by replacing the CwHitScreen component with the CwHitScreenFill component. This causes the polygon shape you draw to be filled in with a grid of points. Keep in mind the points are drawn in screen space, so the resolution depends on the camera distance to the paint surface.

Mask

This shows you how the CwMask component can be added to the scene. This allows you to define an area where paint will be blocked, allowing you to paint within a specific shape. You can see the location of the mask in the Scene window after you select the mask.

Stretch

This shows you how the CwMask component''s Stretch setting can be used to extend the edges of the mask without modifying the mask texture. This allows you to more easily block painting across a large area without requiring a high resolution mask texture.

Normal Painting

This shows you how normal maps can be painted. This is done by opening the advanced settings for the CwPaintableMeshTexture component, and changing the Conversion setting to Normal, as well as changing the Slot to _BumpMap. You can then paint using the Normal Blend blending mode. Keep in mind the normal maps use all four RGBA channels to store data, so you must set the shape of the decal separately with the Shape setting.

Read Color

This shows you how to read the paint pixel color under the mouse/finger. This is done using the CwReadColor component, which can be added alongside any CwHit___ component that works using raycasts like CwHitScreen and CwHitBetween. Keep in mind the hit component must be set to emit PointsOnUV. The OnColor event is then used to change the UI Image color to the read color.

Event

This shows you how to detect when a specific color has been read, and trigger an action from it. This is done using the CwReadColorEvent component, which can be added alongside the CwReadColor component. When you read a color within the Threshold distance of your specified Color, it will trigger the OnColor event, which can be used to perform any action.

Under

This shows you how the CwReadColor and CwPaintBetween components can be combined, allowing you to read the color under a specific GameObject, and display that color in the UI.

Simulated Multiplayer

This shows you how the CwPaintMultiplayer component can be added to your paint tool to simulate painting over a network. To make this work using actual multiplayer, the SimulateNetworkTransmission coroutine must be replaced with actual network transmission code, which will differ depending on the network solution you''re using.

Procedural Setup

This shows you how to set up a GameObject to be paintable from scratch using C# code. See the CwProceduralSetup script in the PaintIn3D/Examples/Scripts folder for more details.

Triangle Painting

This shows you how to paint the underlying triangles of your mesh. This is done by changing the CwHitScreen component's Emit setting to TrianglesIn3D.

Reveal Graffiti

This shows you how basic painting can be used to reveal a complex design. This is done using the ReplaceOriginal blending mode on your paint tool, which will revert a CwPaintableMeshTexture to its current Texture and Color settings. The texture that will be revealed is first hidden using the CwPaintableMeshTexture.Color setting with 0 alpha. The CwPaintableMesh.OnActivated event is then used to reset this back to full alpha using the CwPaintableMesh.SetColor event, with a hex color of #FFFF.

Counter

This shows you how the Graffiti scene can be modified to count the % of the design you have painted. This is done using the CwChangeCounter component, which monitors the graffiti texture. This component''s MaskTexture is set to read the final graffiti design''s alpha channel so it ignores pixels outside of the design. The Texture setting is then set to the final design, so the currently painted/revealed graffiti texture is compared against the final design.

Draw Angle

This shows you how to make painted decals change direction based on the angle of your mouse/finger as you paint. This is done by changing the CwHitScreen component''s RelativeTo setting to DrawAngle when RotateTo = Normal. Keep in mind the draw angle isn''t known on the first frame your mouse/finger touches the screen, so the first paint hit is skipped.

Local Mask

This shows you how to mask specific areas of your texture using your mesh UV, rather than being in 3D like with CwMask. This is done using the CwPaintableMeshTexture component''s LocalMask setting inside the Advanced settings.

Paint From Code

This shows you how to paint decals under the mouse from code. Check out the PaintIn3D/Examples/Scripts/CwPaintFromCode.cs code to see how it works!

Flow

This shows you how the Flow blend mode can be used to move the pixels in the texture you paint using a normal map that defines which direction and how far they should move. The maximum distance of the flow samples can be controlled from the Kernel setting.

Gradually

This shows you how to make paint flow across the surface of your object over time. This is done using the CwGraduallyFade component with BlendMode = Flow. This allows you to set a normal map in the Texture setting that allows you to control how the paint should flow.

Time

This shows you how the Flow / Gradually demo scene can be modified so the paint begins at full speed, but gradually slows down until it stops. This is done by adding a second paintable ''Speed'' texture to your object. Since this speed texture isn''t applied to the material, you must enable the Advanced / IsDummy setting. Like the albedo texture, this speed texture uses CwGraduallyFade to twist the texture around, but it also has a second CwGraduallyFade to fade it to black to slow down the speed. The albedo texture''s CwGraduallyFade.MaskPaintableTexture is then set to this speed texture, which will cause its flow speed to depend on the speed texture''s red channel. You can then paint both the albedo and speed textures at the same time to make the effect work. Keep in mind both of these textures must use a different CwGraduallyFadeGroup setting.

Liquefy

This shows you how to make a liquefy paint effect, where the painted pixels will move based on the direction you move the mouse/finger when painting. This is done using the Flow blend mode with a normal map pointing up. The flow is rotated using the CwHitScreen component''s RotateTo / Relative To = DrawAngle setting.

Primitive Painting

This shows you how to configure the four basic primitives to be paintable, so that any paintable pixels that enter them get painted. This is done using a combination of CwHitNearby and CwHitThrough components with the CwPaintSphere and CwPaintDecal components to continuously paint any pixels that enter the current volume. Keep in mind the CwPaintDecal.NormalFront setting should be set to 2 to apply paint even if it's applying to steep or back faces.

Line Painting

This shows you how to paint points or lines between the mouse/finger start and end positions. This is done using the CwHitScreenLine component, which can be combined with the CwPaintSphere/Decal component. This component''s Frequency setting can be used to control how many and where the points/lines are drawn. The ConnectHits setting can also be used to switch between drawing points and lines. Keep in mind painting lines on complex geometry requires you to paint many points, otherwise they will go through the geometry.

Arrows

This shows you how the CwHitScreen and CwHitScreenLine components can be used together to draw lines. This is using a combination of other settings, like Frequency, and setting Rotate To / Relative To to Draw Angle.

Debug Painting

This shows you how the CwPaintDebug component can be added alongside your other paint components. This will show you where Paint in 3D is applying the paint in the Scene view. This allows you to easily diagnose painting problems. Keep in mind this feature requires you to enable Gizmos.

Delayed Appearance

This shows you how to make paint gradually appear after you paint it, rather than instantly. This is done by configuring two CwPaintableMeshTexture components as normal. However, the first should have its Group setting changed to an unused group (e.g. DUMMY), and the second should have its Advanced/IsDummy setting enabled to prevent it from applying to the object''s material. A CwGraduallyFade component is then used on the first paintable texture with the Replace blend mode, and the BlendPaintableTexture set to the second paintable texture. In effect this means your paint will apply to the second paintable texture, and this paint will be gradually copied over to the first. The other settings are just to prevent paint from applying directly to the first paintable texture.

Command Serialization

This shows you how to listen for and store paint commands that get added to any CwPaintableMeshTexture component in the scene. You can then click a button to reset all paintable textures, and randomly apply one of the recorded paint commands. See the PaintIn3D/Examples/Scripts/CwCommandSerialization.cs code to see how this works. Keep in mind this is an advanced technique that requires good C# knowledge.

Clip Connected

This shows you how to eliminate the overlap points from transparent painting when using the Advanced / Connect Hits setting. This is done by enabling the Advanced / Clip Connected setting, which blends connected lines together.

Dynamic Mask

This shows you how to make a mask texture at runtime from a camera. This is done by making a new camera with its TargetTexture set to a RenderTexture in your project. A separate Screen Space - Camera UI is used to render to this camera (you could also render 3D objects). The RenderTexture is then added to a CwMask in the scene. In this example only the Red channel of the mask is used, so the RenderTexture uses the R8 format to save memory.

Initial Tiling

This shows you how to initialize a paintable texture with texture tiling. This is done using the CwHitNearby component with the PaintIn setting set to Start. The CwPaintSphere component is then used to apply the paint. This component's Advanced/TileTransform can be set to any GameObject/Transform that has scaling, and you can set the Advanced/TileTexture to your desired texture. When you enter play mode, these components will activate and apply the paint to your scene. Make sure the CwPaintSphere.Radius setting is large enough to encompass your object. To isolate painting to just one paintable texture you can drag and drop your object into the CwPaintSphere component's Advanced/TargetModel setting.

Depth Mask

This shows you how to mask paint behind foreground objects. This is done with the CwRenderDepth component, which can render the scene depth from the perspective of a camera. All paint components with the Advanced / FindDepthMask enabled (it''s enabled by default) will then be depth masked.

Expanding Paint

This shows you how to make paint that expands or rotates over time. This is done using the CwHitScreen and CwSpawner components, which will spawn a prefab under the mouse/finger when you click/tap the screen. The spawned prefab has the CwHitNearby and CwPaintDecal components, which make the spawned prefab paint every frame/Update. The prefab also has the CwPaintAction component, which is used to call the CwPaintDecal.MultiplyScale or CwPaintDecal.IncrementAngle functions to animate the paint. Finally, the CwDestroyAfterTime component is used to destroy the prefab after some time.

Bullet Dents

This shows you how to paint holes and dents on a transparent target object. The bullet mark ignores transparent areas using the Alpha Blend blending mode, with only the RGB channels (1, 1, 1, 0), skipping modifications to the alpha channel.

Car Decals

This shows you how the Undo Redo demo scene can be combined with Sphere and Decal painting so you can paint on a car.

Chalk Board

This shows you how the Seamless Painting and Blur Painting demo scenes can be combined to create a chalkboard you can draw on and erase from in a realistic way.

Clean Dirt

This shows you how to apply dirt to an object using the P3D/Solid shader''s albedo override texture. You can then clear the paint by changing your brush to the Replace blending mode, with a color of transparent black (RGBA = 0000). The CwColorCounter/Fill/Event components can then be used to show how much has been cleaned, and show the "CLEAN" text when it''s below 2%.

Dripping Paint

This shows you how the Collision Painting and Flow / Time demo scenes can be combined to create a paint dripping effect that slows to a stop over time. Unlike the Flow / Time demo scene, this uses a downward facing flow texture, so the albedo and speed textures flow down the wall.

Fireball Holes

This shows you how the Nearby Painting / Throw demo scene can be modified to cut holes through an object.

Paint Ball Throwing

This shows you how the Color Counter demo scene can be modified to paint splats of color.

PBR Painting

This shows you how to paint the Albedo, Normal, and PBR (Metallic + AO + Smoothness) textures at the same time using the Group feature. You can assign a texture group using the CwPaintableMeshTexture.Group setting, and to paint these textures a matching CwPaintSphere.Group/CwPaintDecal.Group setting can be used.

Rock Engraving

This shows you how the albedo and normals can be painted at the same time, creating a rock engraving effect.

Rock Throwing

This shows you how two CwPaintCollisions components can be used with different layer filtering and different Root settings, allowing you to apply different kinds of paint to different objects. The CwPaintDecal component and CwPaintableTexture''s GameObject must have matching layers for this to work.

Shield Impacts

This shows you how CwHitCollisions and CwPaintSphere can be added to a Rigidbody GameObject. This allows them to paint the Spaceship_Shield GameObject with a special impact pattern. The CwGraduallyFade component is then used to gradually fade the texture back to transparent black, simulating a spaceship shield effect.

Skybox Painting

This shows you how to paint a background skybox without seams or distortion. Notice the skybox mesh is a subdivided cube turned into a sphere with cube mapped UV coordinates. The mesh is then run through the Seam Fixer tool.

Splat Map Painting

This shows you how to paint an RGBA splat map. This is done using the Splat (R, G, B, A) group, with the Replace blending mode. Each paint tool replaces the splat texture with a specific channel color (e.g. 0,1,0,0 for green). It''s also possible to use the Additive & Subtractive blending modes on each channel instead. Keep in mind splat maps require your object to have a special material/shader that implements splat maps.

Spray Paint

This shows you how to paint an object using a spray can that emits paint particles. This is done using the CwToggleParticles component.

Transparent Object Painting

This shows you how the albedo of a transparent object with overlapping UV data can be painted using auto generated UVs and secondary textures.

VR HVLP

This shows you how PBR spray painting can be implemented in VR using Unity''s XR library. Make sure to enable Virtual Reality Supported in your project settings. Also, make sure to select the VR Manager GameObject, and check to see if each input axis is set up. If you''re using the new InputSystem, then please read the documentation for it.

VR Pen

This shows you how VR pen painting can be implemented in VR using Unity''s XR library. Make sure to enable Virtual Reality Supported in your project settings. Also, make sure to select the VR Manager GameObject, and check to see if each input axis is set up. If you''re using the new InputSystem, then please read the documentation for it.

Wheel Dirt

This shows you how to particle collision painting can be used to apply dirt to a car as its wheel kick up dust.

Zombie Blood

This shows you how to paint dynamic blood decals on an animated SkinnedMeshRenderer GameObject. These decals are painted using the Multiply RGB blending mode, which causes them to stack and get darker. Keep in mind the zombie uses a big BoxCollider, so the decal must extend quite far into the zombie to paint it. This is done using a high CwPaintDecal.Scale.z setting, and with the CwHitScreen.Normal = RayDirection setting, to rotate the depth so it faces the paint direction.
