catchyid Posted November 26, 2020 Share Posted November 26, 2020 hi, in a bullet solver, once I break the constraints between pieces they fly super quickly in different directions, any idea why? thx Quote Link to comment Share on other sites More sharing options...
catchyid Posted November 26, 2020 Author Share Posted November 26, 2020 just an update: i increased/decreased collision padding on the packed rbd object but still the same explosive behavior ?? Quote Link to comment Share on other sites More sharing options...
catchyid Posted November 26, 2020 Author Share Posted November 26, 2020 yet another update: i applied the same setup on a simple box and it work ... so my guess is : i am destroying a bridge model and there are many intersecting pieces (actually some pieces are 80% inside another pieces), see image, so when constraints break pieces fly fast, hence the explosive behavior...will verify Quote Link to comment Share on other sites More sharing options...
catchyid Posted November 26, 2020 Author Share Posted November 26, 2020 nope, even if pieces are intersecting intially it won't blow up bullet --> i fixed it, but the fix was super "silly" --> just use the default values for bullet ! (the one that was causing the issue is rotational stiffness, when i set it to default, things got back to normal) 2 Quote Link to comment Share on other sites More sharing options...
