simple bullet sim problem

Recommended Posts

Hello

I have a very simple scene that I need to test.

whatever I do, the connected pieces explodes when they hit the ground.

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

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.

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.
