class FMeshRenderBufferSet

FMeshRenderBufferSet stores a set of RenderBuffers for a mesh

Type	Name	Description
bool	bEnableRaytracing	Configure whether raytracing should be enabled for this RenderBufferSet
bool	bEnableSecondaryIndexBuffer	If secondary index buffer is enabled, we populate this index buffer with additional triangles indexing into the same vertex buffers
FCriticalSection	BuffersLock	In situations where we want to update the existing Vertex or Index buffers, we need to synchronize access between the Game and Render threads.
FColorVertexBuffer	ColorVertexBuffer	The buffer containing the vertex color data.
FDynamicMeshIndexBuffer32	IndexBuffer	Triangle indices
UMaterialInterface *	Material	Material to draw this mesh with
FPositionVertexBuffer	PositionVertexBuffer	The buffer containing the position vertex data.
FDynamicMeshIndexBuffer32	SecondaryIndexBuffer	Partition or subset of IndexBuffer that indexes into same vertex buffers
FStaticMeshVertexBuffer	StaticMeshVertexBuffer	The buffer containing vertex data.
int	TriangleCount	Number of triangles in this renderbuffer set.
TOptional< TArray< int > >	Triangles	Optional list of triangles stored in this buffer.
FLocalVertexFactory	VertexFactory	Vertex factory

Type	Name	Description
void	DestroyRenderBufferSet ( FMeshRenderBufferSet* BufferSet )	Enqueue a command on the Render Thread to destroy the passed in buffer set.
void	InitOrUpdateResource ( FRenderResource* Resource )	Initializes a render resource, or update it if already initialized.
void	InvalidateRayTracingData ()
void	TransferVertexUpdateToGPU ( FRHICommandListBase& RHICmdList, bool bPositions, bool bNormals, bool bTexCoords, bool bColors )	Fast path to update various vertex buffers.
void	UpdateRaytracingGeometryIfEnabled ()	Rebuild raytracing data for current buffers
void	Upload ()	Upload initialized mesh buffers. This can only be called on the Rendering Thread.
void	UploadIndexBufferUpdate ()	Fast path to only update the primary and secondary index buffers.
void	UploadVertexUpdate ( bool bPositions, bool bMeshAttribs, bool bColors )	Fast path to only update vertex buffers.
void	ValidateRayTracingData ()	Verify that valid raytracing data is available.
