Motion blur works on some object but don't on others

[lenkiia]

Hi guys!
In this scene, I want the wheels, road, and gears to have motion blur. With the same tag settings, the wheels and road surface have motion blur, but some gears do not.
How can I solve this ?

my project film seems too large that can't be uploaded to here, or if i can upload to anywhere you are willing to download?

Hi,
if the scene is too big, you can share a link via Wetransfer:

Anyway, in general, the issue is caused by using too many octane object tags.
You need to keep it simple, and apply only one octane object tag to the first parent of a group of objects.
No need to add nested Octane Object tags.

ciao,

Yes, I hope that the project can be organized simply, but I still need to use light passes or other staffs under ocatane object tags, and also, disabled motion blur in these tags.
Or do you have some suggestions for my groups organization?
Here's my scene:

It might be a litte complex.
Thank you sincerely!

And by my understanding, the octane object from chlid sets will totally overwrite contect under the octaen object tags from parent sets...

If an object has an Octane Object tag, the information in that tag WILL override the information in an a parent's tag.
