I keep trying to look for the right solution on google, and none of the answers are acceptable or working. When I try to run my map that I am working on, I get this - Someone PLEASE tell me how to fix this. If I can't fix this, then the map, which has been worked on since december, will basically be dead. I don't want that. EDIT - Fixed. I selected the entire map, clicked the texture applicator and set the lightmap scale to 64. It fixed it immediately.
