Not sure what you did but it's simple as putting a tag over car group. I said it in my first answer. See picture

I've tried that multiple times..... it's not working on my version of Octane, so perhaps it's Apple Silicone issue? I get motion blur, but the wheels almost disappear and the car is unsharp. Did you test it?

I've read the manual multiple times and increases frame sampling both in settings and Camera tag. Please assume that I've spent a lot of time trying to figure it out otherwise I wouldn't ask for help here. I just hit a dead end and completely blocked on this.

Hi again
Wheels are rotating fast and will appear weird in Liva Viewer. Have you tried to render in to Picture Viewer?

yes but it's looking exactly the same? what's different for you?

It shouldn't be this hard. Sent the working scene to you

Thanks let me check it out. Upon further test there seem to be various bugs that even when I export as motion vectors, there is still motion blur on vdb's or it changes the way vdb look, shouldn't everything be completely disabled and look EXACTLY the same when motion blur is on as an AOV? otherwise I need to render twice too.

You can also test, when you have a vdb that's on in frame 128 and off in frame 129, with motion blur on it will still show it for one frame more, with motion blur off it won't no matter whether you export a motion vector aov or not.

I consider motion blur to be too unstable when combined with vdb's and camera tracking. I understand it must be a super hard problem to solve, but if passes even start to act funny it becomes very problematic, unfortunately.

Not sure what you mean with on/off! It should not be a problem to make something on/off for motion engine.

What I mean with on/off is turning on and off viewport visibility. Could you confirm, that when you have a vdb smoke object moving at fast pace, and you turn on AOV motion vectors, that the VDB will look EXACTLY the same as if AOV vectors were off?
