Grouping DOP objects by Impact?

Hi,

First time posting here and relatively new to Houdini, so please forgive any poor use of terminology etc.

Basically I want to group DOP objects, specifically RBD pieces, when they are impacted by another object. I want to do this so I can add gravity to each piece as they are impacted. When I look at the geometry spreadsheet I can see the Impacts data appear, but I don't know how to then group these objects by this.

If it helps to visualize what I mean, I've made this puzzle globe made of 500+ pieces, and I'm throwing this ball at it to break it apart. I've got my sim working well enough, but currently gravity is not acting on any of the pieces, so when the ball hits, it's breaking the pieces apart but they are acting as if in zero gravity. So now I want to group this pieces as they become impacted either by the ball, or the pieces next to it, so hopefully by the ends all of the ball collapses.

Thanks for any help,

Alex
