Make the space scene of your dreams using Space Graphics Toolkit. This huge collection of space effects can be customized and combined in any way you like, allowing you to quickly make realistic or fantasy worlds.
With a few clicks you can add this highly optimized atmospheric haze around your planets. This effect is volumetric, so you can seamlessly travel from space to your planet surface. You can create any kind of atmosphere you like with this, because you have full control over the atmosphere color, sunset color, atmospheric scattering, fog, and much more.
This package comes with a powerful planet shader, allowing you to transform your basic PBR planet textures into a breathtaking new world. The detail system ensures your planets look great, even when zoomed in. The water system adds impressive animated oceans, and you even dynamically adjust the water height.
Making planets using normal unity meshes just doesn't work, because each triangle gets too big when you scale a planet to a realistic size. To fix this, you need to use some kind of planetary LOD system. The SGT Terrain feature does this for you, automatically increasing the planet mesh detail as you approach. This feature also comes with components to procedurally alter the height, procedurally spawn objects, and much more.
With the Dynamic LOD and Volumetric Atmosphere features you can seamlessly travel from space to the surface of your planets. The planet surface automatically generates colliders, so you can even land on the surface, spawn normal physics objects, and much more!
Accurate Dynamic Shadows
Unity's built-in shadow system works great for small nearby objects, but it's useless in space. That's why SGT comes with a custom shadow system that allows you to cast incredibly high detail & high performance shadows from planets, gas giants, and rings. This system works alongside Unity's built-in shadows, so your planet surfaces will still look great.
Volumetric Gas Giants
Let's not forget about gas giants! The SGT Jovian component allows you to quickly make impressive gas giants. The SGT Jovian effect is fully volumetric, so you can fly from space and through your gas giant seamlessly. You also get full control over the atmosphere density, atmospheric scattering, rim color, etc.
Did you know that skyboxes are terrible for space games? A 2048x2048 skybox can use as much as 72MB of texture memory, yet still look bad when zoomed in! Space Graphics Toolkit solves this issue using the backdrop feature, which allows you to create cloud/star/galaxy backgrounds that take up very little memory, are fully procedural, look great when zoomed in, and run on mobiles too!
This feature allows you to turn boring spheres into impressively glowing balls of fire that actually look like stars. The corona is fully volumetric too, so you can seamlessly travel from space down to the surface.
If the corona feature wasn't enough, then you can also layer on top some solar prominences. This effect looks great from any angle, and makes your stars look even more impressive.
The last two features make the outside of your star look great, but what about the surface? SGT comes with a star surface shader that is fully procedural, including procedural animation, making your star look alive.
The last three features make your star look great up close, but what about from afar? The SGT Flare feature allows you to make beautiful star flare billboards, just look at the screenshots using them! These flares are fully customizable to your taste, and have advanced features like smoothly occluding behind foreground objects, and correctly rotating to camera orientation.
If your planet has an atmosphere, then it probably has clouds too. The SGT Cloudsphere effect allows you to add a cloud layer on top, giving you control over the colors, distance fading, and much more.
If your planet has clouds, then it probably has lightning storms too. The SGT Lightning effect allows you to procedurally spawn animated lightning around your planets.
To make your planets look more exotic you can add the aurora effect, which adds glowing trails over the poles. This effect is procedurally generated and animated, and also heavily optimized. If you don't like the preset colors or shape then you have full control over how they are generated.
The SGT Ring effect allows you to quickly add a planetary ring around your planets. You can easily control the ring inner & outer radius, enable light scattering, add an animated asteroid detail map for when you get close, and it even splits the ring up into multiple segments to correctly handle depth sorting!
The Singularity feature allows you to add impressive black holes to your scene in just a few clicks. This effect bends light from objects behind it, and you get full control over the radius, distortion power, and can even add an unrealistic but cool looking color tint around the edges.
Allows you to create animated accretion discs, with full control over the inner & outer radius, light twist strength, animation speed, etc.
If you really want to show off what gravity looks like, then you need to use the SGT Spacetime effect. This allows you to visualize the gravitational distortion caused by planets/stars/etc, and even allows you to simulate gravitational waves.
Space is big, and to simulate movement you really need to have things whizzing by the player. The SGT Starfield Infinite effect allows you to make infinitely repeating clouds/stars/dust that flies by the camera as you move.
Space Graphics Toolkit comes with a powerful starfield generation system, which allows you to create elliptical galaxies, spiral galaxies, and much more. These starfields render with incredible performance, detail, and you have the ability to customize every aspect of their appearence.
Space Graphics Toolkit includes a number of systems to prcoedurally spawn asteroids and other debris around the camera. These can be spawned in orbits like the asteroid belt, around the camera so players can interact with them, and much more!
Floating Origin System
If you've ever tried making massive scenes in Unity, you know that everything starts to break very quickly. To fix this, you need to use a floating origin system to keep everything close to your camera. SGT comes with an advanced yet easy to use system that allows you to simulate a universe over 50 billion lightyears in each direction! It also comes with procedural spawning components so you can quickly fill all this space up.
You're not just limited to fantasy worlds when using Space Graphics Toolkit. With careful adjustment of the settings you can also achieve visual results that are almost indistinguishable from real life, making it perfect for space simulations.
