Your problem seems due to culling face culling, your inventor model seems to
have been created for rendering with no face culling and two sided lighting,
you could try to affect a change in the face culling from the Inventor file,
if not you can do it in Performer:

pfCullFace(PFCF_OFF);
pfOverride(PFSTATE_CULLFACE, PF_ON);

or change the geostates concerned if youre drawing more than your inventor
model.

This will turn off backface culling, then you've only got twosided lighting
to worry about.
