Thanks!
There is no support of nurbs, there is no support of bezier (an exception of
lathe and prism). Refusal of nurbs and bezier is a concept?
Badly. It strongly limits possibilities of data transmission from the Blender to
Povray.
I can't give animation, I can't give the arrays built along curves
Interestingly, what 3D - editors have no nurbs and bezier, but have cubic and
quadratic? I such didn't see.
If I wrote the AutodeskMaya2Povray exporter, I would meet the same problems?
:(
