Hi, I need to draw a shower with tile that does not go to the ceiling. I am using glass walls for the surround and a custom backsplash for the wall tile. I inserted a niche and I can add tile to the back but when I try to use the material painter on the sides of the niche, it adds tile material to the whole wall to the ceiling. Is there a certain way to do this so that only the sides of the niche get tile? I have experimented with using thin soffits around the sides of the niche but the tile doesn't wrap into the niche correctly. Any other work arounds? Thanks!
