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
}
}
}
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.
