I am having a problem, which is, that while you are in-game and look up at the ceilings, you can spot the room markers in some new rooms I have added to my Mod.
The weird thing is, that it doesn't fix it, if I turn the tiles 90 degrees. If I do that, the room markers become visible another place in the room.
The problem only occurs in the new rooms, that I have added to my Mod, which isn't released.
I have thought, that it may be because I am using some wrong tile, but I am not sure about that. I think I just copied the hallway (which is where the problem occurs, to be more precise the problem right now occurs then the hallway and the new rooms meet).
Is there some way around this problem? - I would be happy, if someone could help me out
