I'm struggling to get motion blur working with some animation in LOPs which is driven from CHOPs.

I've got a chain of transform LOPs and they're working correctly in the viewport but motion blur doesn't work either with Motion Blur LOP or cache LOP. If I put a keyframed transform in there instead it works as expected. Right clicking on the driven parms and doing bake keyframes does nothing.

Is there some particular workflow for this? I guess I could do a SOP modify, do the transform in there and use a trail SOP for velocity MBlur but that seems very hacky.

Thanks for reading

I should have added, I'm using 20.0.724

Hmm in fact I just set up a test scene with just a cube and a chop driven transform and that did work...

So I copied in my chain of transform LOPs and initially that didn't work, even thought he animation was still fine in the viewport. I fiddled around with channel names, un-exported, re-exported etc and all of a sudden it worked. I have reverted all the settings to how they originally were and they're working still.

So I can only guess that it's a bit buggy. I will try repeating the process of turning things off and on again in my actual scene... Hopefully this will be a bit smoother in 20.5...
