Well im compleatly stumped. I made this map, it has glass inside the doors. sometimes while standing at different angles to the doors or even some of the walls in the map, you can see right thru them into a black void. The same thing happens to brushes with the
"func_breakable" entity tied to it, or "func_door/func_door_rotating" which makes things you shouldnt be able to see visible before you should see them.
!?can anyone help me?!
