Ahh I see. Glad they implemented that.
All I can think of is a method that I similar to my initial approach, just using the speed of the pushed objects to add momentum to them.
Sadly I haven’t had much experience with physics programming. So I can’t declare that this is an optimized method.
Literally utilizing an “Add force” node could work after collecting information on the velocity of the objects and initiating it when the sphere stops growing could work. But might not be very efficient.
Sorry for lack of a better solution.
