I have a mesh with a rigid body that moves back and forth like a platform. Other rigidbodies fall onto the upper surface of this cube. The problem I have is that when the platform rigid body moves the other rigid bodies stay in the position they landed in, they do not move with the cube. Everything else physics wise works.
I have tried adding a physicsmaterial to both the platform and the rigidbodies falling onto the platform but this made no difference.
I do no want to tether them to each other because I want them to fall off when they are pushed by other objects.
The platform is moved back and forth using the RigidBody.MovePosition function.
