Recently I have decided to try and use HDR in my map, but when compiling, I noticed that nothing changed in terms of lighting. When I dug in further, I tried putting mat_hdr_enabled into my console, it simply says "HDR is disabled" underneath. I also tried mat_hdr_level 2, but it says I can't change this value in multiplayer games. Is HDR just not supported in tf2 or something?
