penetration during convexHull & btBvhTriangleMeshShape

[xle99]

Hi,

I am new to Bullet library, I want to simulate one object (convexHull) drop to another static object (btBvhTriangleMeshShape), the convexHull object should slide along the static object.
But got the penetration problem, the convexHull object always penetrate the static object.

Does anyone know how to solve this problem?

Thanks.
