References

Module	SlateCore
Header	/Engine/Source/Runtime/SlateCore/Public/Rendering/SlateRenderer.h
Include	#include "Rendering/SlateRenderer.h"

Syntax

virtual void InvalidateAllViewports()

Remarks

Removes references to FViewportRHI's. This has to be done explicitly instead of using the FRenderResource mechanism because FViewportRHI's are managed by the game thread. This is needed before destroying the RHI device.
