Maya Objects and Physics

Hi all! I have imported a box from Maya and i would create a pinball game. I added a mesh collider to the box and a sphere collider to the ball. I have added rigidbody to the ball.

Now…my ball collides with box. I don’t know why, but after some bounces, the ball fall into the box and goes out from the box. Why??? :°°°°( Thanks for the answers…

I got something like that too, when the ball was colliding too fast against a surface… You can tweak the Rigidbody params “Interpolate” and “Collision Detection” to avoid that.
