colliders for detail rockes?

hi so i was wondering if it is possible to make colliders for detail painted rocks.

i know you can use capsule colliders for trees but it does not work for detail meshes.

thanks.

If a box,spehere or capsule collider (or a group of some combination of these) isn't accurate enough for your purposes then you can use a MeshCollider.
