When you look at the image below you'll see what I mean. You see the wall texture below the Impanzee Room on the left with the texture that goes under reinforced walls and rooms. We also see that walls I've reinforced multiple levels high show both the standard reinforced wall texture, but also the texture that would show up on the tiles beneath them if they were just non-reinforced rock.
