I'm losing color on Inventor objects loaded into perfly (without options) if
they've been previously optimized by ivfix. The object colors appear correct
when the same optimized files are read into ivview or SceneViewer. I've
included a short Inventor file below that exhibits this problem. Any ideas
would be appreciated.

Thanks,
Bob Doyle
