Why AWPRigidBody objects on the basis of AWPBvhTriangleMeshShape not react to collisions with other AWPRigidBody objects on the basis of AWPBvhTriangleMeshShape?

but each object is correct react to a collision with a AWPBoxShape

Sorry for bad English.

BvhTriangleMeshShape is for static geometry only.  So objects can collide with it, but it will not react to collisions itself.

well, then give me a hint how I can do what I want.

There are two simple model, it is necessary that they collided with one another.
each collision area is a simplified mesh object.

I do not seem to understand much, but
AWPDebugDraw.DBG_DrawCollisionShape shows how both areas pass through each other without colliding

if your model is convex polyhedron,  you can use AWPConvexHullShape.

thanks a lot.
this is exactly what I needed
