EMaterialKeyInclude

enum class EMaterialKeyInclude : uint32

strong

Categories of fields which should be included in a ShaderMapId or in the output of a FMaterialKeyGeneratorContext. GetShaderMapId, and code recording or emitting fields to a FMaterialKeyGeneratorContext, calls HasAllFlags for the flags relevant to a given field before writing it to the ShaderMapId's ShaderTypes or to the FMaterialKeyGeneratorContext's RecordAndEmit functions.

Enumerator
ShaderDependencies	shadertype, shaderpipelinetype, vertexfactortype dependencies are included in the output
SourceAndMaterialState	shader hlsl file hashes are included in the output
Globals	Global data that applies to many or all Materials is included in the output. For calculating the ShaderMap Id, this includes The ShaderTypes, ShaderPipelineTypes, and VertexFactoryTypes in the Material's FMaterialShaderMapLayout. For the output of FMaterialKeyGeneratorContext this includes globals (cvars, project settings) that impact The Material's FMaterialShaderMapLayout via GetShaderTypeLayoutHash. The ShaderPlatform being emitted via ShaderMapAppendKey. All Materials via FMaterialAttributeDefinitionMap::AppendDDCKey.
UObjectData	data stored in UObject exports in .uasset and .umap files is included in the output
All
