Iron doors and wood doors have odd effects, minor but noticeable. place a door in a flat land, look at it, (hinges are the grey/black part)hinges on one side, and the other, that's okay, but place a door like the screen cap and it has hinges on all sides. [UPDATE] if the door is on any wall it will have hinges on the narrow part of the door.
