Hi Paul, thanks for your reply. So wait to see what Foundry says about this? And you don't need a simple scene?

Image sequences are working on the fly in Modo. But I can't get it to repeat. It stops at the last frame. End Behavior is Repeat.
With an Octane Override and some tweaks the image sequence is also working. But no repeat here either.
Is this possibe?

Thanks. I had the same problem some years later.
