One of our R&D engineer also made an algorithm to split meshes automatically into equal chunks super quickly, so that may come in handy.

Another thing you could try is disabling RTX acceleration in Octane preferences, since there will be some data we don't need to prepare in that case.

to chop the big trunks into small pieces (inside octane automatically) will be important for Octane,
not only for meshes but also for big textures(e.g. 8k map), as I remember this is the bottle neck which also make Nvlink not working well...
hope this issue can be resolve soon.

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 :)
