jsa, I'm currently playing with Rhino Evaluation, and might help: when you're exporting, FI, .3ds, don't raise the number of polygons. The middle setting of the slider is just fine. .obj also has a problem with the settings, but I just tried that last night for a minute and don't remember exactly what. I think you should uncheck the bottom check-box in the dialog window that appears when you choose .obj as the export format. I didn't do that and object was "imported" but nothing showed up in Bryce. Also, have you tried playing with the angle of polygons during the export? I'll try checking when I get home. BTW, P4 1.7, 512 RAM, Win 2000.
