Baking Mesh with Multiple Assigned Materials (CYCLES)

Alright Blenderheads,

I have got a Mesh that has several Materials on the mesh. When I try to bake these to an image, it will only bake the portion of the mesh that has the selected material applied to.



as you can see, the first material is selected and the part of the mesh that has that material has only been baked out.

Anyone know a way to get around this?
