Enumeration Type Documentation

◆ ECompiledMaterialProperty

enum ECompiledMaterialProperty

Enum that contains entries for the ways that material properties need to be compiled. This 'inherits' from EMaterialProperty in the sense that all of its values start after the values in EMaterialProperty. Each material property is compiled once for its usual shader frequency, determined by GetShaderFrequency(), And then this enum contains entries for extra compiles of a material property with a different shader frequency. This is necessary for material properties which need to be evaluated in multiple shader frequencies.

Enumerator
CompiledMP_EmissiveColorCS 
CompiledMP_PrevWorldPositionOffset 
CompiledMP_MAX 

◆ ECompiledPartialDerivativeVariation

enum ECompiledPartialDerivativeVariation

Enum that contains entries for the ways that material properties can be compiled with partial derivative calculations. Standard material shaders using the automatic hardware FiniteDifferences, Nanite uses Analytic, and we will likely need to add a separate one for raytracing at a later date.

Enumerator
CompiledPDV_FiniteDifferences 
CompiledPDV_Analytic 
CompiledPDV_MAX
