Member Function Documentation

GetFriendlyName()

FString FMorphVertexBuffer::GetFriendlyName ( ) const

inlinevirtual

Morph target vertex name

Reimplemented from FVertexBuffer.

GetLODRenderData()

inline

GetNumVerticies()

SIZE_T FMorphVertexBuffer::GetNumVerticies ( ) const

inline

GetResourceSize()

SIZE_T FMorphVertexBuffer::GetResourceSize ( ) const

bHasBeenUpdated

bool FMorphVertexBuffer::bHasBeenUpdated

Has been updated or not by UpdateMorphVertexBuffer

bNeedsInitialClear

bool FMorphVertexBuffer::bNeedsInitialClear

DX12 cannot clear the buffer in InitRHI with UAV flag enables, we should really have a Zero initzialized flag instead
