I have a similar problem with a code that works very well on my 4D25TG but
really sc**ws up on my 4D320VGX. That as well is with Gouraud-shaded polys
(triangs and quads) that have a nice soft shade on the 4D25 but are multi-
colored facets on the VGX. 

The code was recompiled from the 25 to the 320...

Vitals are

   . IRIX 3.3.1 on both
   . infinite lighting model
   . pretty simple shading model
   . no textures
   . model size ... less than 3,000 polygons

Any hints ? I hate to tell all my users that... oh well.. you better stick to
the Personal Iris.. the VGX isn't feeling too well these days..."
