Ok digging further into what the flag the cancel motion blur flag does I’m beginning to think it’s bugged.
I was able to get access to the debug motion blur render targets via the vis command.
When the game is running hit r.RDG.ImmidiateMode 1 to make the Render Dependency Graph run in immediate mode. Then hit vis Debug.MotionBlur.Flatten to visualize the debug render target. I’m not 100% why you have to set these flags in this order, but if you don’t VisRT won’t show the render target.
