UActorComponent::IsRenderStateRecreating

function Engine Since 4.0

#include "Components/ActorComponent.h"

Access: public

Description

Returns true while the render state is in the process of being destroyed and recreated due to a MarkRenderStateDirty call. Useful for components that want to preserve certain render state across the recreation.

Caveats & Gotchas

• This flag is only set during re-creation triggered by MarkRenderStateDirty, NOT by RecreateRenderState_Concurrent or editor bulk-change operations. Don't rely on it as a general 'proxy is being rebuilt' sentinel.
• The window during which this returns true is very brief — it's set just before DestroyRenderState_Concurrent and cleared after CreateRenderState_Concurrent completes.

Example

Preserving render state data across a dirty-driven recreation C++

void UMyComponent::DestroyRenderState_Concurrent()
{
	if (IsRenderStateRecreating())
	{
		// Save data we want to hand back to the new proxy
		SavedProxyData = CaptureProxyState();
	}
	Super::DestroyRenderState_Concurrent();
}
