When I load exported bvh onto a standard max biped, there are error messages about missing finger joints. the hands scale down almost to zero as well. This never happened on version 1.

Saving out as a biped file as I usually do sorts this, but I thought you might like to know anyway.

IPI 2 is a really great improvement, and the tracking is much more accurate, as far as I can tell.
I got useful results with a dual K system very quickly. I like the cleaner workflow and new recorder interface.

Thanks for report, we'll investigate this issue.
Also thank you for the warm words about new release :)

Check out the latest release 2.0.0.132. Does it fix this issue?
