From Jan Peciva,

"I was working on a new version of Inventor plugin.
It was inspired by the need to get correct and high quality conversion,
so I verified the plugin on complex models and made number of serious fixes:

- the geometry is not two times on the output file (!)
- SoVRMLImageTexture: VRML texture support was rewritten according to
  Inventor programming practices, since it does not worked correctly on
  many models (Anyway, thanks for Gerrick Bivins to introduce it.)
- osg::ref wrong usage related crash fixed
- code cleaning and texture code overhaul
- LOD fixes
- appended README.txt with all the contributors I was able to get from
  SVN logs"
