Well, no it's not gonna unless by "smoothing groups" he actually means "using the vertex normals from the OBJ file to do the shading"...


Well, maybe Phil can use the cube example, that's a very simple example and it's always easier for someone to analyze simple cases.

I guess you may want to just avoid trying to use Octane with any CAD data until the most basic stuff like just getting a cube in works though.


Maybe tomorrow or whatever could you do one more test with the attached file?


That's an unwelded file (with one version from MoI and one version from Rhino), and if it shows a segmented looking result in Octane instead of a smooth looking cylinder, then that definitely shows that vertex normals are not being used for the shading. That's another very simple case that you would probably want to be working in Octane before it would really be suitable for rendering any CAD data.
