Setting the first vertex point

If you have the Exercise Files that came with this lesson, I'm going to go back to my Comp panel, Close All, and then open up comp 03-Interpolation where I've already created a couple mask shapes for you. If you don't have the Exercise Files just sit back and watch. This is a fairly easy concept. Here I have a black solid where I've already created two different mask shapes at different keyframes. This first shape of a maple leaf and this second shape of an oak leaf, cool! Now since that keyframing going on, you would just assume this is going to interpolate between those two shapes, but look what happens when I RAM Preview.

I press 0 on the numeric keypad. This leaf is turning in on itself. It's not at all animating the way I expected. What's going on? That's because After Effects really cares about the order that you draw mask points. It looks at the first point you draw for one shape and tries to interpolate that to the first point you drew for another shape....
