Hi Michael,
Hi Maxim,
As far as I can remember KeyShot(HyperShot) never really handle .3dm NURBS data very well it always relied on the mesh data in Rhino files.
Another good export option is STEP, I found KeyShot converts STEP data pretty good.

Cheers

Hi Danny - re: STEP - one issue with that is that material (style) assignments on different faces within the same solid will not go through with STEP, but it will with OBJ format. OBJ is just a more commonly used way to transfer render data...

Hi Michael,

You're right about the individual faces you loose that with STEP or KeyShot used to, I haven't been keeping up with it lately so I don't know if anything has changed.
I mention STEP because of the two stage result; save as STEP, import into KeyShot, where as .obj is; save as, manipulate mesh, then import into KeyShot. I know some engineers that don't want to mess around with meshes, they just want a quick picture and KeySot's meshing of STEP files is pretty smooth.

Cheers
