This was a real pain in the ass to make (since shortcuts didn't work so well with the treads) because each one had to be manually edited into position (all 89 of them, actual 178 since it's split into 2 distinctively different pieces). I also did a little tweaking on the rear wheel that attaches to the engine and the other 8 wheel placements.

This render does not justify the damn thing at all, but I really don't want to sit through another render session.
