Thanks for the run-through! Much appreciated.

I can't see any actual conversion taking place, though. It's just a simple copy of the joint angles between the figures, and factors like the difference between the angles of V4's and V3's feet aren't taken into account. However that could conceivably be taken care of by a little Python, if I'm careful in the choice of figures I use to substitute for the lo-res ones. I think I can cook up a solution.
