Hi

I've not been able to solve shading problem yet.

I do not know what else to check...

        My Multigen model has been shaded dynamic gouraud.
         
        My polygons have one normal per vertex.

        I've checked the tolerance and shading angle... They are good.

The result is as follows...

        Once I calculate shading the model is smoothly shaded in MultiGen.
Unfortunatly when I go to performer via 'trackball.c' my model is very
faceted. Trying to solve this I have shaded in multigen using dynamic,
gouraud, dynamic gouraud, and flat. All seem to produce the same
result.

Side note: I use a great deal of material properties in this model...
with specular and emissive properties. I also tried changing the
lighting mode attribute of the models polygons from flat to
dynamic,gouraud. It didn't help in soving the problem.
             
Thank you for any help you can provide,
