A way of running a physics simulation on only a single rigid body instance.

Hi. I’m looking for a way of running a physics simulation on a single rigid body instance where all other objects in the physics scene would be inert. The simulation would also need to be run independently of the world tick i.e. inside of a while loop.

This isn’t really how things are meant to work in the physX world. You could try using the async scene for your single rigid body. Your static physics bodies would also be in the async scene but at least none of your dynamic objects would interact with the odd object.
