Small problem with a no doubt simple answer. I have an env_sun entity in my map that appears when I compile, no problem. When I build cubemaps, it vanishes. These are the commands I use: sv_cheats 1 mat_specular 0 buildcubemaps disconnect mat_specular 1 mat_reloadallmaterials map <mapname> In that order. sv_cheats goes on when I'm already in the map, if it makes a difference. I also tried using mat_reloadallmaterials after reloading the map instead of before, but it didn't make a difference.
