Quote - If you are using the Octane Standalone app, IMO the best workflow is NOT click the obj mesh and tweak the materials.  Instead, create new glossy, diffuse, specular materials and plug them into the material connection on the mesh (even for the emitter lights).  Then if you tweak the mesh in Poser, simply reimport and replug the material nodes into the right inputs on the mesh.  They way you don't "forget" what settings you had.

Is there a way to grab the material from the OBJ and drop it as a new material node?  Like a copy paste?  Sure would be easier to start that way.
