stabilize object to the ground

[xindro]

There are options to bind to the default ground plane in the PhysX Bind settings. Alternatively you can bind to a PhysX Collider as well (your own ground).

You can also use a PhysX Switch operator to set lower particles to kinematic (unmoveable by PhysX forces). You could enable a filter in that operator to, for example, only set particles with a position Z value less than some height threshold to be kinematic.

Thank you so much for the quick respond! I will try, thanks again
