I was done with this little animation a while ago, but let's just say that sometimes Real Life comes along and kicks you in the rear.
This is my example of an underground lake. I had originally worked on this as backdrops for a yet unreleased mod. I decided to re-do my project using walls. It took three walls to accomplish this effect. I was going to have a stream coming in or going out of the lake, but that would be 3 more walls.
I don't think there is any savings on the amount of art done by choosing walls over backdrops, but it is simpler to code in DC.
