Well, I'm embarrassed to post mine.
I am so thrilled at finding an object that was a titled floor! But, no way am I populating it with the 580 seats the auditorium holds! I'm going to repeat the process with 2 more "titled floors" for the walk ways. I want to add a screen and curtains, but it's not important for the overall concept.
HOWEVER: Even though I am slacking and skipping some details, in my case I know what I can get away with. It is generally a good idea to try to build up your environment as best as possible. The more details, the better.
