Pov-ray does not really use polygons (unless it is a mesh) and it needs a tesselator or something similar that will convert the geometry into polygons. A few weeks back someone tried to do this but he could not clear all the bugs in it. It required a recompile of Povray. Go to the povray newsgroup (check the povray page for details) for more information. Povray is not really designed for export of geometry. Crossroads will convert povray meshes but the support is limited. It will not convert procedural surfaces. good luck, FlyerX
