Mesh collider without Rigidbodies

Question

Hey guys, I decided to use a mesh (without Rigidbody) in place of Unity's built-in terrain, and I attempted to attach a meshCollider (non-convex). However, the collider doesn't seem to work, and I can't use convex as that would just ruin gameplay. Any thoughts, suggestions or alternate methods?

(Important: I'm using a asset called "Polybrush"!) alt text

Select the object you want a mesh collider for.

In the toolbar at the top of the page in Unity, click on Component/Physics/Mesh Collider.

Find the original prefab object in the project window and its mesh (child) object. It has like an xray view with vertices

Drag the mesh object onto the mesh onto Mesh Collider (MESH)

Make sure to remove rigidbody and it'll work.

Yeah, what you suggested works but here's where it gets a little different: I'm using a asset called polybrush, which allows me to reshape meshes. But with mesh colliders, it's treating the mesh as if I made no changes.
