I'm not aware of morphing support in OSG. For skinning only there is
an osgCal nodekit which allows you to use cal3d models in OSG. Not
sure about Skin Wrap, but Skin & Phisique modifiers are ok. There are
3dsmax exporters in cal3d distribution.

The animation of transparency, specularity or texture maps is not
supported in exporter nor osgCal. Probably you can make it by direct
manipulation of state sets.

Also I'm working on more advanced exporter (based on cal3d one) which
contains some bug fixes, exports bumps, normal maps, opacity, and some
other material properties plus it automatically exports all textures
and compress them into .dds format. The my version currently not in
production state, but I can upload it somewhere if you want.
