object contains one or more SubShaders. SubShaders let you define different GPU settings and shader programs for different hardware, render pipelinesA series of operations that take the contents of a Scene, and displays them on a screen.

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 ShaderLabUnity’s language for defining the structure of Shader objects. More info

, you define a SubShader by placing a SubShader block inside a Shader block.

Example

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.
        }
    }
}
