***Oh nevermind, I figured it out, disregard the below I had not assigned any materials to the objects before export from C4D***
For some reason when I export a scene with multiple objects to Octane, it only gives me one object in Octane. It is not possible to select one individual object for giving a material etc. It is as if all objects are seen as one. This is both with the plug-in and manually importing the mesh.
I have attached an image of what I mean. There are clearly three objects but Octane see only one. Maybe there is something simple I am missing?
