Hey guys, super helpful thread, thanks! I'm trying to extend this to inherit the initial velocity of each packed prim once they become active. But primitives that get activated over the course of a simulation don't inherit v when they start to sim.

Is there something I'm missing on the object to get each piece to inherit velocity when its activated? This file is netvudu's, modified slightly.

Thanks!

I did have to bring velocity into the dops network by over writing. Remember that pesky check box to disable on the rbd packed object "enable sleeping .

I used a solution like this. In my sop solver connected to the rigid body solver. I use a point wrangle with:
if(distance(@P,{0,0,0})<@Frame/5)
    if(i@active != 1) {
        i@active=1;
        v@v = fit01(rand(v@P), -10, 10);
        }
So we can add random velocity only when the object switches to active.
