I found an awesome tutorial at https://www.highend3d.com/maya/tutori...rs/starwars.3d

However im having some trouble with it. When it says, "Let's now make the toe empty by using the same technique. We turn around the view until we see the rear face of the polygonal toe. we select it as a face, as we did before, but now when we are in the extrude mode, we don't move it around like we did before but we use the scale manipulator instead and scale the face until we obtain a uniform profile. now let's select one more time the extrude function and move the face this time towards the inside part of the toe. Look at the picture below to have an idea of what you should have obtained out of your model."

what is the scale manipulator lol! I am new to maya...
Anyway thanks ahead of time and check out the tutorial.
