Hi! I'm looking to make a continuous looping animation of RBD fracture geometry and my scene is working but I don't know how to randomly assign single pieces of geometry in the For Each loop to the particles in the DOP Network.

I started out with (https://www.sidefx.com/forum/topic/51033/?page=1#). I added a sphere going into an RBD material fracture and then transform each piece to bring into center.

From there I am I trying to copy it onto points in the DOP network and that's where I'm getting stuck. It's copying every piece of geometry in the loop to every point. I tried putting some expressions into the Target Points field of Copy to Points using the For Each metadata but it gave a warning saying it wasn't a valid selection.

Thank you for reading this. I appreciate any help and responses.
