I'm not sure how to make light rays shine through a window into a room, I don't know if that is even possible?
You might have a clip brush over the map blocking your movement, I had that problem with my map. I accidently pulled it over my map.
Everytime I run my map it ends before I can spawn in, I know it's not the .gsc file and my fpstool texture is on my map. Does anyone know why thats happening?
