    If you don't need a rigidbody on the object you can simply apply a mesh collider and keep it concave and that can work. If you need realistic gravity but nothing else you can look into using a character controller with a script that moves something down based on a gravity equation. If you need a rigidbody you can split the mesh up in blender into multiple convex parts then when adding mesh collider select convex (probably not good for animated objects). If none of these are applicable then you have to make it from a series of other colliders like the box and capsule. I do that by parenting a separate game object I don't render at runtime and apply a semi transparent material to it.
