Redshift is now, for all intents and purposes, C4D's new render engine. It comes pre-installed with all C4D installations. More and more C4D assets are generally being offered only with RS materials, not the old standard/physical engine materials. The problem here is that the only conversion tool is from the old abandoned render engines to Octane, not from RS to Octane. I know ion the past we haven't done third party engine to Octane conversion because there's too many of them, but now RS is the standard C4D engine.
Could we get a RS to Octane converter? I would settle for the basics, just bring in the diffuse, normals, bump etc and any basic colours. This will at least give us a starting point and all the correctly applied materials for us to then improve and finish off.
