This is a "fixed" version of the BM_C3A2H map with rebuilt cubemaps.. That should fix the "over bright" or "AAAAARGH.. IT'S BURNING OUT MY RETINAS!" issue with models in the map that use cube mapping.. When playing the BMS mod with the high dynamic range option turned on.. You'll just need to extract the contents of the ZIP file to the MAPS directory of the BMS mod and overwrite the older .bsp and .ain files.
