Exporting Child in Parent/Child to BVH

kairk_bf57c0e06c

I'm creating animations for Second Life, and I've got 1 figure as a child to another (I did it hip to hip in Animate2 because of the way Second Life uses the hip), and is simply following the parent figure. Is there any way to export the child motion information to a BVH file?

When I export it, the values for the child in the BVH file are all zero, I'm assuming because all the motion information is in the parent.

I can get close by using a parent/child relationship in the scene tab, but that puts the motion information in at the figure level, not the hip level needed by SL, and I can't find anyway to convert between the two.
