I am wondering if anyone has had any luck getting this to work.
I am trying to do some packed RBD magic with objects and take some control over the center of mass. I have attached an example scene in which the pivot of the packed objects is clearly established before it goes into DOPs. However once in DOPs this pivot get switched to the calculated centroid as soon as the sim starts.

I have tried disabling the “Compute Center Of Mass” option, and I get the same results whether I create the RBD packed object manually or with the shelf button (which adds that crazy expression in the Pivot channels). I even tried adding a pivot attribute in SOPs. Nothing works at sim time.

Would be great to get any thoughts about getting this to work.
FYI: We are working in 14.0.361
Thanks so much for your help!
