This video is getting lots of hits on my own website.
It’s quite old now, made about 18 months ago. It uses ragdoll dynamic simulation that is part of the Havok engine in 3ds max 6. I can’t see a way that would allow a pre-loader that can be hosted on live.space. For now, I recommend that you press pause (II) if the video seems jumpy, let it all load, then resume play (>).
