Follow along and you will end up with a rendering like this: Ray tracing theory _Color("My Custom Color", Color) = (1,1,1,1)} SubShader {} SubShader {}} // Sub Shader Unity shader can have different sub shaders to support different hardware features For eg: one subshader for iPhone and another one for Playstation Many simple shaders use just one Pass, but shaders that interact with lighting might need more, depending on the rendering mode of Unity (ie. A User Showcase of the Unity Game Engine. Light Maps and Probes. I don't think anything in the game will require DirectX-anything. As this is lighting functionality we'll put it in a separate Lighting HLSL file. With it we can customize a lot about how the material that will use our shader will be used internally.
