Public function void

Init ( TArrayView< const uint32 > ElementScatterOffsets,
uint32 InNumBytesPerElement,
bool bInFloat4Buffer,
const TCHAR* DebugName

 Init with pre-existing destination index data, performs a bulk-copy.
Public function void

InitPreSized ( uint32 NumElements,
uint32 InNumBytesPerElement,
bool bInFloat4Buffer,
const TCHAR* DebugName
)

 Init with presized num scatters, expecting each to be set at a later point.

Deprecated Functions

  Type Name Description
Public function void

ResourceUploadTo ( FRHICommandList& RHICmdList,
const FTextureRWBuffer& DstBuffer,
bool bFlush
)

 Scattered uploads to FTextureRWBuffer will no longer supported in a future release. Use a supported destination buffer type instead.
