Variable Documentation

GRHIMergeableAccessMask

RHI_API ERHIAccess GRHIMergeableAccessMask

extern

Mask of states which are allowed to be considered for state merging.

GRHIMultiPipelineMergeableAccessMask

RHI_API ERHIAccess GRHIMultiPipelineMergeableAccessMask

extern

Mask of states which are allowed to be considered for multi-pipeline state merging. This should be a subset of GRHIMergeableAccessMask.

GRHIMultiSubresourceDiscardIntermediateAccess

RHI_API ERHIAccess GRHIMultiSubresourceDiscardIntermediateAccess

extern

[NeedsTransientDiscardStateTracking] State to use as an intermediate state when transitioning to discard and the resource has differing prior states per subresource.
