Member Data Documentation

◆ AsyncBatches

TArray<FBatchItem, SceneRenderingAllocator> FInstanceCullingMergedContext::AsyncBatches

Async (and thus added as to the above as late as possible) Batches of GPU instance culling input data.

◆ Batches

TArray<FBatchItem, SceneRenderingAllocator> FInstanceCullingMergedContext::Batches

Batches of GPU instance culling input data.

◆ BatchInds

TArray<TArray<uint32, SceneRenderingAllocator>, SceneRenderingAllocator> FInstanceCullingMergedContext::BatchInds

◆ BatchInfos

TArray<FContextBatchInfoPacked, SceneRenderingAllocator> FInstanceCullingMergedContext::BatchInfos

◆ bMustAddAllContexts
