Hi everyone!

Happy New Year!  Hope you're all well!

Here's a free public post, a bit of a holiday gift.  I was hoping to get this posted on Christmas Day or New Year's Day, but was a bit too busy right up until Christmas.

In my destruction classes & SideFX conference presentations I've mentioned that I often use geometry grouping to define the clustered sections in my RBD sims.  However, it takes a bit of work to create the feedback for-each loops to set that up, so I've finally wrapped it up into a helpful HDA.

I also included the HDA in the November 2020 'quick tip' post, but this version fixes a bug in the size-based prioritization, so if you have that version I highly recommend downloading this one instead!

Hope you find this useful, and that you enjoy the new year!   :-)
