I integrate a system that can build vertex streams asynchronously.
So I spawn tasks in my FPrimitiveSceneProxy::PreRenderView override, then in FPrimitiveSceneProxy::DrawDynamicElements I wait those tasks.
But sometimes, PreRenderView is called but DrawDynamicElements is not called. This is a a problem to unlock vertex streams among other tings.
Is there a kind-of- PostRenderView somewhere, or a way to know in PreRenderView that DrawDynamicElements will not be called this frame ?
