I notice this only hapens when the top plate has a lot of hulls (like 280), but when I lower the hull numer the plate just passes straight trough the rivet.why is this happening?</P> Wed, 16 Oct 2019 11:54:03 GMT https://forums.autodesk.com/t5/3ds-max-forum/problems-with-massfx-an-object-goes-to-infinity/m-p/9089492#M29505 Anonymous 2019-10-16T11:54:03Z https://forums.autodesk.com/t5/3ds-max-forum/problems-with-massfx-an-object-goes-to-infinity/m-p/9089883#M29506 <P>Can you post an image of your scene setup?
