I think 3ds is just a geometry format, and doesn't have support for 
hierarchical models (somebody please correct me if I'm wrong). 

Probably the best way to get what you need to get the OSGExp plugin for 
3ds MAX, and export the model directly as a .ive file.

If you have the COLLADA-DOM set up for OSG, you could also try exporting 
from 3ds MAX to a COLLADA (.dae) file.
