Add a subshader in a custom shader
Use a SubShader block to add one or more sections that define different GPU settings and shader programs for different hardware, render pipelines, and runtime settings.

A Shader object contains one or more SubShaders. SubShaders let you define different GPU settings and shader programs for different hardware, render pipelines, and runtime settings. Some Shader objects contain only a single SubShader; others contain multiple SubShaders to support a range of different configurations.
For information on how a Shader object works, and the relationship between Shader objects, SubShaders and Passes, see Shader objects introduction.
In ShaderLab, you define a SubShader by placing a block inside a block.
SubShaderShaderExample
This example code demonstrates the syntax for creating a Shader object that contains a single SubShader, which in turn contains a single Pass.
Shader "Examples/SinglePass"{ SubShader { Tags { "ExampleSubShaderTagKey" = "ExampleSubShaderTagValue" } LOD 100 // ShaderLab commands that apply to the whole SubShader go here. Pass { Name "ExamplePassName" Tags { "ExamplePassTagKey" = "ExamplePassTagValue" } // ShaderLab commands that apply to this Pass go here. // HLSL code goes here. } }}
