when you use the calc. shading tool in multigen you must specify the "lighting
mode" radio box. the loader will only use the model's normals if the lighting
mode is "Dynamic" or "Dynamic Gouraud".

I am a wee bit confused...the original post mentioned that it was smooth
when loaded into perfly. I would then assume that both perfly and Julie's
application would use the same Multigen loader, and therefore something in
either app is changing the shading mode...hence my previous post.
