Well, if frames are wrong when you create the constraint, then there is a big error to correct for the constraint at the very first step, so even without colliding, these two objects would have a huge force applied to bring them back to the (only one) correct relative position/orientation.Mako_energy02 wrote: I've also been thinking more and more about the frames being wrong...and I am thinking less and less that to be the case as I don't really understand how that would cause the objects to exert force on each other if collisions are disabled, furthermore the objects in almost all cases end up where I would expect them to when they collide...so the frames are correct based on observation of the objects(but I haven't directly observed the data yet).
Changing the erp to a very little value should help minimizing the force used at the very first step, but the counter step is that the constraint will take more time to resolve. But it would finally show you the relative positions/orientation (frames) you actually set (and therefore show you if there is an error on it).
Just to make sure we understand each other: changing the erp value to a very little value is not the solution, it's just a clue to help us understand where the problem stand.
