A task context for use with parallel for that allocates a command list for each task thread.

Example Usage:

FRenderCommandList* ParentCommandList = FRenderCommandList::Create();

UE::Tasks::Launch(UE_SOURCE_LOCATION, [ParentCommandList] { / Closes recording of the command list on completion of the scope. FRenderCommandList::FRecordScope RecordScope(ParentCommandList, FRenderCommandList::EStopRecordingAction::Close);

/ Constructs a parallel for context with the command list as the root. FRenderCommandList::FParallelForContext ParallelForContext(ParentCommandList, NumContexts);

/ Issue a parallel with a command list per thread. ParallelForWithExistingTaskContext(TEXT("ParallelFor"), ParallelForContext.GetCommandLists(), ..., [] (FRenderCommandList* InRenderCommandList) { FRenderCommandList::FRecordScope RecordScope(InRenderCommandList);

/ Commands are recorded into InRenderCommandList. }); });

ENQUEUE_RENDER_COMMAND(... [] { ... }); // Command A

/ Submit the command list at any time. All included render commands are patched between commands A and C. ParentCommandList->Submit();

ENQUEUE_RENDER_COMMAND(... [] { ... }); // Command C
