By the way, I do high quality VR art pieces and as I mentioned, for video-games (especially VR), you want to have as few objects as possible. So that means you will have few objects, but they are all huge. I also bake all my lighting with Octane because it is so fast and beautiful.
So while I will be able to split my scene in this case because I'm not making a VR game, it would be good to find a long term solution to this that allows users to load giant scenes with large chunks of geometry (to reduce draw calls)so that Octane remains a good solution to bake the lighting in these scenes
