Hello all.

I would like to design a radial gravity force field to manage a bunch of rocks attracted by a point. The reason I need a radial gravity is because I want to compute the mass of each piece for the interaction between them BUT I dont want the mass taked into account by the force. I tryed a radial field with a magnet force driven by a metaball but it didn´t work: little pieces are accelerated faster than bigger ones. Anyone has a clue how to design the radial gravity witch doesn´t take into account the mass of the RBD´s?

Thanks in advance.
