we are using Rhino/Octane combination a lot in our product design work. We have built our material library, so our designers can simply drop materials on the objects and render. Main issue for us is that - there is no preview of the materials in rhino viewport (shaded or rendered). So, user can't even tell if materials are applied to object without selecting it and looking in material editor tab.
I should point out that most of our materials are created as a "NodeEditor' Octane material. This dictated by the fact that it's much easier and much faster workflow for creating and adjusting materials.
For example, we can use noise image texture for bump as a triplanar map. This will eliminate need for UVs. And we can link all of the XYZ parameters of triplanar map to one texture node and ONE uv transform node for easier and speedier workflow.
Paul, Is there a way we can solve this ? Maybe, this could be resolved by creating Octane viewport mode in Rhino? Where all of the octane materials will be previewed correctly.
We are using Rhino Version 6 SR16 (6.16.19190.7001, 7/9/2019) and Octane for Rhino Build: 18.104.22.168
Rhino 7 WIP have same issue as well.
