motion blur turns to boxes

[affixxius]

Hi
I have a simple set-up, one model in cloner, plain effector with spherical fall off making them scale up, then back down. All is fine, until they scale off, they change into cubes/boxes. Anyone any idea why this might happen? I've tried increasing the motion blur steps, octane tag is applied to cloner, I've tried every iteration of cloner instance type plus the 3 types of motion blur in the tag. Copied to a new scene, changed camera...
All help appreciated
cheers

Try increasing the Time Sampling per Frame value in Render Settings > Octane Renderer > Main tab. Start with 4 and go from there.

Hi mate,
Thank you for your reply. I have tried with different time sampling per frames as suggested, at 5, it sort of works, probably good enough as its fast, but anything above or below still gives me boxes.
Are there any other ways to improve MB, or perhaps is it better to use something like real smart motion blur in cases like this? (fast fast moving stuff)
Thanks again

It all depends on how fast your rotations are. I have seen people take that number over 50. I usually go with 10 myself.

I don't advice to go high as 50,etc... It takes much time to precalculate and consumes much memory
