3ds max Biped, motion caps and mecanim rig

I was desperate how to use bvh motion caps on normal max bones without a need to go through motion builder, so I decided to make myself a rig constrained to biped. In this way I'm able to use layers and edit motion captures that we make with kinect. But it became a bit difficult to edit that rig to reuse it on another character, so yeah, knowing some max script I made this tool that creates bones on top of a biped. So anyone interested try it out, it's free.

If you are really interested I might do some changes, so let me know what you think. But don't expect I will do some drastic changes since I don't have much time to work on it.
This is what you can do:
