Unfortunately, its not that simple. I wish it was. I used Poser Pro 11's rigging features and weight map copying features to get the setup initial. I used Poser File Editor 3 to copy the weight map text into a form that I could mathematically modify and then had to copy them back in for testing. I used Excel because I couldn't think of anything else. It took me more than three days to get everything working.

Now I need to automate all this. So it only takes seconds.
