Is there possibly a stand-alone version of Vray that might work better for your rendering than a Rhino plug-in one?

Normally a rendering system should now be able to read in MoI's new OBJ export and have materials set up and ready to be rendered.

In other renderers, the Styles become translated as a materials list, which is all prepared to edit any of the materials to adjust the render properties of all the objects that are assigned to that.

I guess your main problem is that Rhino's OBJ import does not really read in material information properly to keep the list of named materials that is stored inside of the OBJ file, is that correct?

If that's the main problem, then that is really a bad function of Rhino's OBJ importer - it should read in materials from the OBJ file as a table of materials that you can edit. If the closest thing to that in Rhino is layers, then it should build layers from OBJ materials.

It seems like much of your problem in this case is that Rhino's OBJ importer just does not seem to function as a regular rendering program's OBJ importer does.
