Hi,
This is a very helpful thread!
Works well for me, but I have one issue… If you look at the attached image, you will note that the motion path created as suggested above is appearing with hard angles and not a smooth curve.
In my case, I parented a light to Null 1, instead of using a 2nd null.
Any idea why my circles are harsh? Is there a way to refine?
Thanks!

Thanks,
Ari
