Advanced Unity Shaders
summary
Shows concrete code and workflows for advanced Unity shaders: using a script to set a global float via Shader.PropertyToID so many materials share a single wind parameter; building a camera-to-screen matrix with GL.GetGPUProjectionMatrix × worldToCameraMatrix and writing it to a global float4x4; rendering a depth RenderTexture with camera.Render and decoding that depth to compare distances and make projector/shadow effects; packaging shared functions in .inc CG include files and adapting Unity’s lighting code to run multiple forward lights in one pass (example: five lights).
