herr.ja Posted May 20, 2020 Share Posted May 20, 2020 Hello, Houdini folks! I have a question about very essential thing durring the rbd simulation. (Im attaching the file here). What I have, I want to change the scale of the pighead, durring the simulation, but without this "strange jumping" behaviour. Any suggestions, how to solve? Thank you so much. strange_behavior.hip Quote Link to comment Share on other sites More sharing options...
ikoon Posted May 20, 2020 Share Posted May 20, 2020 Hi Michal, you are scaling the object, but at the same time, you are translating it (because of the pivot of the scale). This is the main reason for the unusual behavior. Set the translate in testgeometry_pighead1 to 0,0,0 and set the translate in transform1 to 0,5,0. Then you could also increase the substeps of the dopnet and/or the bullet solver. Quote Link to comment Share on other sites More sharing options...
