Using the Fallback block

To assign a fallback, you place a Fallback block inside a Shader block.

Fallback code examples

This example code demonstrates the syntax for creating a Shader object that has a named fallback.

Shader "Examples/ExampleFallback"
{
    SubShader
    {
        // Code that defines the SubShader goes here.

        Pass
        {                
              // Code that defines the Pass goes here.
        }
    }
