Hey Chris,
No i dont know the particulars. It seems to be insinuating that it is reading in, and representing NURBS data, and so i just assumed that was the case.

Maybe it can be inquired about in the keyshot forums (when does the tessalation actually take place). There are alot of keyshot users here in this forum also.aybe someone already knows and can clarify....

Hi BurrMan & Chris, if you import MoI 3DM files, the NURBs are imported directly. You will need to tell KS5 & 6 to render NURBs data. As far as i know all other NURBs formats have the option to tessellate upon import. Simple rule of thumb, if you try to import a file and KS reports a no geometry found error, the check the import NURBs data option and you should be good to go.

For KeyShot, the "Import NURBS" option mentioned above is under the Geometry section of the Import options dialog, it's shown around 30 seconds in on the video Pilou links to above. Here's a link to a bit larger displayed version of the video:

I mostly export OBJ to KeyShot. They render much faster and importantly, if exported from MoI correctly, allow for small fillets to be added to the geometry at render time, creating even more realistic renders.

Just my 2 cents.

I just requested the render time filleting for SimLab a few days ago ... hopefully will make into the development cycle.
