Hello guys!

I use a POP metaball to add force in a bunch of fragments with glue constraints. To break the constraints, the Rigids3 tutorial sets up a SOP Solver that retrieve the “force” attribute of the simulation geometry. However, this attribute remains 0 for the whole sim.
I also tried with a magnet force instead of the POP, but the value doesn't change either.

I must mention that I use a bullet solver, instead of a rigidbody solver like in the tutorial. I tested with a rigidbody solver and it's working fine.
Is there a specific way to make it work with bullet ?
