I assume this isn't possible at the moment, but it would be a very nice perk for us Corona customers to have access to a form of the V-Ray Bridge to allow us to convert a scene to Corona. Not render, just allow a conversion. I can't tell you how much time this would save me. I buy a good amount of models and it hard to find C4D+Corona all ready to go. Many model do however, offer C4D+V-Ray. If I could just hit that convert button and get 90% there, I'd be a happy man.
Since they are both Chaos products and it wouldn't take away from their customers, this seems like a no-brainer to me.
