I'm streaming my D&D games and would like to chromakey the backdrop so the map can just sort of float on the screen. The problem is some of my players have issues with eye strain and headaches, so having the odd strong blue/ green surrounding the map might trigger issues for them. So ideally, I'd like to change the backdrop just for myself so the other players aren't affected but I can still have the map floating on the screen. Is there anything that can be done, or will I have to live with a floating black window for now? Thanks!
