Unity 5 - Animator and Mesh Renderer

I was looking at the 2D roguelike tutorial (http://unity3d.com/learn/tutorials/projects/2d-roguelike/player-script) for information on how to animate 2D sprites in Unity 5.

However, while this works with sprites I would like to be able to apply the same logic to a Mesh Renderer used for rendering a Quad.

This is my current set up for a Quad:

Currently the mesh displays the entire texture atlas as opposed to using the frames from the animation (sprite rectangle coordinates).

How can I get the Mesh Renderer to correctly display the animation frames?
