I finished a map (ctf_installation) a few weeks ago: http://www.fpsbanana.com/maps/45191 Playtesters compliment me on layout and detailing, but the lighting seems to be a problem. Especially the high-contrast central canyon area suffers from a strong bloom effect on the concrete floor. The battlement floors also seems too bright. I reduced HDR lighting in the light_environment, but am hesitant to reduce the light values further because it may become too dark. Vrad and cubemap building take very long and I know it will take days of trial-and-error to get an acceptable lighting compromise. Is there any other way to reduce the blooming effect? I could replace the textures with darker ones, but there has to be an easy way because Valve maps don't suffer from this. Help and advice would be very much appreciated.
