I tried every possible way that I think of but couldn't figure out why a simple sim can't be done correctly. please help I'll much appreciate . thank you circle bullet.hip Quote Link to comment Share on other sites More sharing options...
woodenduck Posted February 4, 2019 Share Posted February 4, 2019 Concave collisions are not stable in Bullet. Spend some time converting the geometry in to convex hulls by either fracturing it, or making the points unique and polyextruding a small box per face. Make sure you check the "convex hull per set of connected primitives" on the bullet object. Quote Link to comment Share on other sites More sharing options...
benne5 Posted February 4, 2019 Share Posted February 4, 2019 Instead of making using your objects as rbd packed objects make them a glued object. This will create a constraint system between the packed pieces. Quote Link to comment Share on other sites More sharing options...
