tweetytunes: Awsome, thats a really easy way to do it!

There is also another way to do it, via the connection editor. But you have to go through the hypershade to do it. It's really easy to do, and the connection editor is a snap to work. The whole process is like 4 or 5 clicks of the mouse. Really easy stuff.

Arran: My directions are comming from maya 6.5 so it doesn't hurt to try both methods. Not all of the mental ray nodes are preset so it's good practice to learn how to apply them manually like I have shown.
