Credit to Pablo Román Andrioli for the 'Star Nest' Algorithm. Animated Procedural Skybox effect using the Star Nest algorithm, ported from ShaderToy/GLSL Sandbox to Unity3d Contains 3d skybox and 2d surface shaders with easy access to shader parameters in the editor. Perfect for any game that needs procedural space backgrounds. Note: Shaders are a bit expensive, and not intended for mobile. Option to reduce the quality or disable them entirely should be included with any shipped game, even on Win/Mac/Linux.
