Name Type Remarks Include Path Unreal Specifiers
CBVDescriptorRangeFlags D3D12_DESCRIPTOR_RANGE_FLAGS   D3D12RootSignatureDefinitions.h  
CBVRootDescriptorFlags D3D12_ROOT_DESCRIPTOR_FLAGS We always set the data in an upload heap before calling Set*RootConstantBufferView. D3D12RootSignatureDefinitions.h  
PackedShaderKey const int32 Key used for determining whether shader code is packed or not. D3D12ShaderResources.h  
RayTracingPrecompiledPSOKey const int32 Key indicating whether serialized ray tracing shader contains a DXIL library or a precompiled PSO. D3D12ShaderResources.h  
SamplerDescriptorRangeFlags D3D12_DESCRIPTOR_RANGE_FLAGS   D3D12RootSignatureDefinitions.h  
SRVDescriptorRangeFlags D3D12_DESCRIPTOR_RANGE_FLAGS Assume descriptors are volatile because we don't initialize all the descriptors in a table, just the ones used by the current shaders. D3D12RootSignatureDefinitions.h
