light_spot and point_spotlight don't appear to be working in my map. I can't figure out why and it is incredibly frustrating. I've even gone so far as to steal lights wholesale from other maps (including the light prefab vmf on this forum) and nothing works at all. The only reason I can find for this happening is if HDR brightness is -1, but it isn't -1 anywhere and anyway my light_env works perfectly.
Help please?
