        Hi!

         

        I'm writing an AR-app where I want some physics-enabled elements to be placed a plane attached to an ARAnchor.

         

        However, whenever I place any object on top of the anchored plane node that represents the floor, the objects jitter and bounce as if the movement caused by readjusting the floor propagates to the physical objects colliding with it.

         

        I'm at a loss to what I should do with this. Some collision shapes are more suceptible to this effect than others. SCNBox shapes usually stay still. Any automatically generated convex collision shape causes a bouncy castle rave party.

         

        If it is indeed the constant readjusting of the floor plane that causes this jittering, is there a way to have the physics coordinate system be relative to the anchored node instead of world coordinates?
