The fog is just four 64x64 baseplates put on top of the build with the Fog Weather emitter.
Oh what?
Dammit, then I should do that.
Anyways, here's a method to stop spawnkilling:
Put a wall with a door in front of spawn zones, and the door has no events whatsoever. Name the door something, then on the side where the team spawns, put a 1x1x4 brick in front of the door, and make it no collision and rendering, but has raycasting. Event that to open and close the door, so people on the outside can't open it.
If you confus, PM me so I can make something to what I just said.
