I'm having a strange problem when running Performer programs on our ONYX, and I
was wondering whether anyone has had to deal with that before. It seems almost
like the Z-buffer is backwards. In the demo, there is a car circling around a
town. When the car goes behind a building, you can still see the car. Also,
when you zoom in on the car, all the parts of the car are backwards -- you see
the trunk instead of the front of the car when it is facing you.

Has anyone ever seen this before? Does the ONYX somehow work differently fromn
the other machines? We've run it on Solid Impacts and Max Impacts without any
problems. Is there a patch that fixes it?

Thanks, in advance.
