How to make a Rigid Body fall off a conveyor belt? I've created conveyor belt and and two objects with rigid body physics.
But the first object won't fall and second object falls backwards.

How can I fix it?

This is because the rigid body simulation is only taking the initial deformation into account, behaving as if the curve modifier is applied:



To fix this, enable Deforming on the belt object:



This will make the simulator take into account deformations of the object that occur during the simulation.

Result:
