Classes

  Type Name Description
Public class FMember A member of a shader parameter structure.  

Enums

  Type Name Description
Public enum EUsageFlags Additional flags that can be used to determine usage  
Public enum EUseCase The use case of the uniform buffer structures.  

Constants

Name Description
kRootCBufferBindingIndex Shader binding name of the uniform buffer that contains the root shader parameters.

AddResourceTableEntries ( TMap< FString, FResourceTableEntry >& ResourceTableMap,
TMap< FString, FUniformBufferEntry >& UniformBufferMap
