Hi, do you use the Blender for Octane addon or standalone only?
Anyway, all objects need to be UV- unwraped to work with Octane even the default cube.
Octane use own materials, Octane diffuse, Octane glossy and so forth.
It is a bit outdated but basic information is there:
Sorry, there might be a language barrier here, but it sounds as if you want Octane to render Cycles materials? That’s not going to work. Cycles nodes for Cycles, Octane nodes for Octane.
Other than that I have no idea what you’re talking about, sorry…
And frankly, I’m still unclear if you’re talking about the special “integrated” version of Octane Render for Blender (with the OctaneRender server, the one you pay for) or just the Octane exporter plugin (the free “unofficial” one; both links might only be visible for licensed Octane customers)?
