Set shader variables with material property values

Using material properties to set variables in ShaderLab code

To set the value of a variable in your ShaderLabUnity’s language for defining the structure of Shader objects. More info
See in Glossary code from a material property, put the material property name in square brackets in your ShaderLab code.

This example code demonstrates the syntax for using a material property to set the units value of the ShaderLab Offset command.

Shader "Examples/MaterialPropertyShaderLab"
{
    Properties
    {
        // Change this value in the Material Inspector to affect the value of the Offset command
        _OffsetUnitScale ("Offset unit scale", Integer) = 1
    }
    SubShader
    {
        // The code that defines the rest of the SubShader goes here

        Pass
        {
            Offset 0, [_OffsetUnitScale]

           // The code that defines the rest of the Pass goes here
        }
    }
}

Using material properties to set variables in HLSL code

To set the value of a variable in HLSL code using a material property, give the material property the same name as the shaderA program that runs on the GPU. More info
See in Glossary property.
