Concrete garage floor

[Kilgore Trout]

When I tried what you did my floor was concrete and not terrain. But I also noticed that when you open up the room dialog and change the floor material that it doesn't do anything. The dialog says the right flooring but it still shows up as the original material. I couldn't find anywhere to change the default material but the spraycan seemed to work. Have you tried using the spraycan yet?
