If you're interested, these are some samples of the theory. Nothing complicated. Just some PAP examples. You can use them on a Mil figure. However, because the Mil figures do not come with pointAtParms slots in the cr2, you must first apply a "point at" to each eye through the menu. After that, clicking on any one of these will bounce you all over the scene, and the eyes will follow wherever you go. It also works for props (like a sphere), if they are declared as actors.
