Hello, I don't get Nurbs to render. A simple scene with a nurbs sphere won't render. Using H 10.0.265. Then I installed a version of H 9.5 and the problem stays… Are there special parameters to render nurbs objects with Mantra? If I render with Prman everything works… thanks, bern

Hello, If I leave the “imperfect” option unchecked, the nurbs sphere does render… thanks, bern

Something to do with rational/non-rational surfaces then…. odd I assume if you convert the one that doesn't render to polys all is well?
The trick is finding just the right hammer for every screw

For the record, I'm running 10.0.266 on 64 bit linux and all variations of the NURBS sphere renders fine. Cheers, J.C.

yes, if I convert to polys the render is fine.
What can be the cause of this…pc processor (AMD)?
thanks,

Bernard Simon What can be the cause of this…pc processor (AMD)? Offhand, I'm don't see why but you can test by setting these environment variables to 1. HOUDINI_DISABLE_MMX HOUDINI_DISABLE_XMMX HOUDINI_DISABLE_SSE HOUDINI_DISABLE_3DNOW
