Hello,

I have a problem with Motion Blur and a Cloner.
When I animate (offset) objects along a spline, I get big strange lines appearing.



I cannot get rid of these lines... (I tried Alignment Before/Center/After)
Any idea?

C4D 2024.5.1
Tested with Octane 2023.1.3 R5, 2023.1.2 R7 and 2024.1 R2

Thank you!

Looks to me like it's actually correct, because your clones are looping from the end and back to the beginning of the spline. Because of this, a clone with any given ID may be at both the beginning and the end of the spline during the frame exposure. You might be better off using a true particle system where each particle dies at the end instead of being recycled to the beginning of the spline.

Alternately, you might have each clone become invisible for the short time it makes the transit from end to beginning of the spline, plus a little overlap on each end.

Thanks Franck for your reply, that's what I was afraid of. Not really Octane's fault here...
Initially, I'd done it with particles (fused) but my scene is more complex (a network of moving deformed tubes connected with a flow of particles inside) and I still have leaking particles for the moment. So I explored this simpler solution... and encountered its Motion Blur problems.
I'll think about your alternative, thanks!
