Fixed position error in left snaps bone in the 3 section models.
At a long distance away from prop you may still get some bleed through of flooring but it is level now. Pulling the section up off the floor a bit then snap the rest of the objects to that will keep that from happening.
This is brilliant, and the music for the demo movie was cool too. Very nice!
