I want to add and inverted effect to half of my screen, with the post processing everything is inverted, so I want to use it as a window, like everything the camera sees thru it is inverted, nothing else, thanks!!

Howdy ThePangel, thank you for posting such an interesting scenario.

This sounds too fun to pass up. I found this video by Dean Ashford to see if the effects are the ones you desire. I tested the invert local on UE5 and it seems to work as expected.

Here is my result after following about half the video.
