Here is an animation test, the complete sequence had about 1800 frames but I stop it at about 800 after more or less 3h.
Rendered with direct light and 128 samples per image.
I used blender physics to create the animation and a modified obj export script to export the complete animation for octane.
The file is about 20mb
