I'm trying to enhance my map by using signs but I need to help direct the game play - people are getting lost. I was looking at doing this via door type signs - open-close - and having an arrow sign on the door. If I have a brush and put a sign texture on one of the faces, it they appears transparent on that face. Is this normal? It might look normal in-game but the transparency is making it hard in the map making steps. Any ideas?
