Member Function Documentation

CreateBuffers()

void FStaticMeshStreamIn::CreateBuffers ( const FContext &  Context )

protected

Create buffers with new LOD data

DiscardNewLODs()

void FStaticMeshStreamIn::DiscardNewLODs ( const FContext &  Context )

protected

Discard newly streamed-in CPU data

DoCancel()

void FStaticMeshStreamIn::DoCancel ( const FContext &  Context )

protected

Discard streamed-in CPU data and intermediate RHI buffers

DoFinishUpdate()

void FStaticMeshStreamIn::DoFinishUpdate ( const FContext &  Context )

protected

Apply the new buffers (if not cancelled) and finish the update process. When cancelled, the intermediate buffers simply gets discarded.

Member Data Documentation

CreateResourcesThread

const EThreadType FStaticMeshStreamIn::CreateResourcesThread

protected

The thread to use for recording the above command list

IntermediateBuffersArray

FIntermediateBuffers FStaticMeshStreamIn::IntermediateBuffersArray[MAX_MESH_LOD_COUNT]

protected

The intermediate buffers created in the update process.

StreamingRHICmdList

FRHICommandList* FStaticMeshStreamIn::StreamingRHICmdList = nullptr

protected

RHI command list used for creating buffers and replacing the streaming placeholders. Submitted in DoFinishUpdate
