I've got a really annoying problem with creating doors! I'm trying to make a door to a new room for my Nuclear map (which I had had to delete from the vault because of a bad upload!). I want to get a door that opens upwards like the door to the test lab (big orange door).
But when I try to put one in, it just swings outwards and the wall to the room is still in the bloody way! How do you make upwards doors, and also, do you have to texture the surface of can you just decal them!
