Syntax

class FShaderType

Remarks

An object which is used to serialize/deserialize, compile, and cache a particular shader class.

A shader type can manage multiple instance of FShader across mutiple dimensions such as EShaderPlatform, or permutation id. The number of permutation of a shader type is simply given by GetPermutationCount().
