I am pretty sure this has been brought up before, but I searched and couldn't find it.
In my map, if you look down below the middle of the skybox brush, the skybox disappears, and you see off into the void.
How can that be fixed?
Actually, I think that was due to unknown, un-caulked faces on the skybox brushes. It's fixed now. :naughty:
Actually it wasn't that, either. I had too many brush faces in the map, as it seems, and it was truncating the skybox faces. Deleting faces solved it so far, and it hasn't been back since. I also have some other odd things here and there fixed, too.
