magneto Posted May 6, 2016 Share Posted May 6, 2016 Hi, Does Collision from Object shelf button work? I used it on a basic flip sim and increased the resolution of the collision object and even lowered the Collision Separation parameter on the Flip Object inside DOPs, but I am still getting penetration. Any ideas? Thanks flip.hip Quote Link to comment Share on other sites More sharing options...
Sean-R Posted May 7, 2016 Share Posted May 7, 2016 (edited) Edit - Actually that didn't seem to fix it. I'm not sure why that isn't working, it works fine in a static solver Try setting Scale Source Volume to -1 on the "source_collision_from_box" node Edited May 7, 2016 by Sean-R 1 Quote Link to comment Share on other sites More sharing options...
Atom Posted May 8, 2016 Share Posted May 8, 2016 I think there is something wrong with the collision geometry, the way it is built. If I remove the SourceVolume from the FLIP Solver and then just use the hollow box object as a static rigid body I can get collision after I turn off Volume Based Collision. If you look at the volume based collision object you will see it is full of holes for some reason? Using non-volume based collision, it works..? ap_flip.hipnc 1 Quote Link to comment Share on other sites More sharing options...
Atom Posted May 8, 2016 Share Posted May 8, 2016 Hmm.. that is odd. I went back to try it again after closing and re-opening Houdini and the volume collision object is working properly now. ap_flip.hipnc 1 Quote Link to comment Share on other sites More sharing options...
