Hello UE community!
I am attempting to make a “hall of mirrors” or “smearing” effect (examples below) using post processing nodes. This involves getting the previous frame, and drawing pixels of the previous frame over the area where frames are not recycled. Ideally, this would not involve custom nodes, due to performance already not being too great on my end with post processing, but as long as it works, it works. Doing some very surface level “research” (looking up how to do this,) I found a reddit post about using two render targets and switching between them every frame using a blueprint. Again, not using scene capture components would be ideal, because of the lack of depth, motion, etc buffers (that I know of), and the inability to use it in the node editor preview (that I know of). All help is appreciated!
