What I meant about back and forth was with the renderers. Corona and Vray. I'm a corona user in 3ds MAX. So if I want to use any Vray tools like Project Lavina or this new Vray vision, I would have to covert my current Corona project into Vray and and the export the .vrscene. Are you guys planning on creating a similar app for Corona that would allow users to generate real-time renders and animations quickly...Currently Corona takes forever to generate animations of clean quality unless the user has a farm or uses a service. For single machine users like me, animations are not feasible at the rate clients want them. So I have to plan projects accordingly.
