This might come as no surprise to most of you but I've just reinvented the
wheel. (Or so it seems :)
I've had a lot of problems getting my dynamic clothes to stay on the models when
I import BVH files. I've had to use insane values in the cloth room. Greater
than 200 calculations per frame, Collision Offset and Collision Depth less than
0.25. Even then the simulation was prone to blowing up.
So I looked at the resulting models after applying the BVH files. The generally
have a X, Y, Z offset from the origin. I set the model as a Parent of the cloth
and it carries it with it. The trick is to set the Hip as the parent not the
body as the BVH file applies the offsets to that. You can add additional manual
offsets to the body to position the figure.
Now I can use reasonable parameters and get better results.

Good to know indeed. Seems to be typical to BVH files then, using the hip
instead of the body. I seem to vaguely remember that body and hip have the
same coordinates? The hip being the origin of the figure's motion set. Maybe
that is where that particular BVH things comes from...

I now visualise it as a union within a union.
Union { //Body
Union { // Hip
object{ Head }
...
object{ Toes }
translate // Hip translations from BVH
} //End Hip
translate // Body translations (manual)
} //End Body

Maybe, but *obvious* things are often harder to find... :-)

It is when things go wrong that you need to look at the basics.
