Hi Amin,

please excuse me for not writing for a long time :-( I have some 
comments below.

It is great for now! For later, a more generic solution should be found, 
but your code helps a lot. Thank you :-)

I attached a very simple test that puts three boxes on top of each 
other. Initially, this should work fine since the boxes are setup 
"manually" without any ODE body. If you use the (commented out) import 
command, it will create three boxes with colliders and ODE bodies and 
then you'll see the strange effects that all but the last of the meshes 
in the hierarchy will be stuck in the origin.

It would be great if you could help us with this problem.

Thanks a lot again,
Joschka
