 //
 // The parameters and inspector of the shader are the same as Standard shader,
 // for easier experimentation.

+Shader "BasicRenderPipeline/Standard"

     // Properties is just a copy of Standard.shader. Our example shader does not use all of them,
     // but the inspector UI expects all these to exist.
