You could dynamically create constraints (attach) once they hit the big sphere

you can also use the windingNumber SOP to check if points are inside a geometry.
since packed geo is just "points" representing transforms of your pieces (plus collision hulls and a few other attributes and properties attached to them for RBD sims), you can then group those points (based on their winding number) and in DOPs simply apply your desired force to that group only.

hope this helps

Hello,
we are looking for FX-Artists (Mid & Senior Level) starting asap for about 8-10 weeks.
Should be solid in large scale destruction simulation tasks like RBD, FLIP (Ocean & WW), Volumes & Particles.

Remote work is possible with an NDA to be signed, preferable European-near time zone (for time-related reviews and communication).

Please let me know if interested and available.
Thanks

Fuat
