First, if your Onyx is not an R8000 CPU variety, don't use IRIX 6.1!
Even if it is an R8K, its probably time to upgrade to 6.2.

It sounds like you don't have the model built out of a good material
or you may not have a good light source in the scene.

If you're using "perfly" as the model viewer, make sure that you have
lighting *eye* selected. This will put a "headlight" shining on the
object in question.

If you've spun your own IRIS Performer app, make sure that you have put
a light in the scene looking at what you want to see, or turn off lighting
and watch all the colors brighten.

Good Luck!
