Some Russian guys made a markerless system of motion capture, were you only use a camera, web or not, to film a actor performing a movement and them you use their software and it will make that in a rig with motion capture data. They have a 30 day Free trial fully functional. Why i'm posting this? Because it is a enexpensive solution for indi developers like your selfs and i think it could really help make this mod even better. What you should now about the software. It ONLY works with shader 4.0 capable cards (the powerfull the better) but don't need Vista to run, you can use XP. Now here is the link. http://www.ipisoft.com/
