Hi. I have a bunch of oildrums in my scene that I want to stack on each other… Like this:

But when I press Play in Unity, all the oildrums fall to the ground (not colliding with each other but with the ground). I’ve applied a mesh collider on all of the drums and a Rigidbody.
I don’t want to use a box collider since I want the drums to roll down the street if in a slope or something… (Maybe that can be achieved anyways?)
