Crash always occurs when executing Visualize Texture Command with Texture id.
Looks like GVisualizeTexture.Mode doesn't affect correctly.
Workaround:
VisualizeTexturePresent.cpp
FVisualizeTexturePresent::PresentContent if (Element) { FRDGBuilder GraphBuilder(RHICmdList); // TRefCountPtr<IPooledRenderTarget> ElementRefCount; TRefCountPtr<IPooledRenderTarget> ElementRefCount(Element); GVisualizeTexture.CreateContentCapturePass(GraphBuilder, GraphBuilder.RegisterExternalTexture(ElementRefCount)); GraphBuilder.Execute(); }
Result:
Crash in editor
Expect:
Not crash
