16. Resize and position the alpha plane, your camera, till you get something that looks nice. And there you have it!! A perfect alpha plane in Vue. Now look at the lower right hand corner. Notice that it says 4 polygons. Now if I didn't tell you, and you didn't see this tutorial, you wouldn't know that was an alpha plane. Now to make things realistic, if you're going to make a large woodland scene, render various trees in various shapes, distort them, etc, so that you wind up with 6 or 7 alpha planes of completely diferent "looking" trees, even if they're the same kind of trees. That way, when you have 200 of them in your scene, it will really look like a forest. Remember 200 trees is only 800 polygons. :) Stay tuned for the next series of these tutorials called: Alpha Planes Part 2: Things get Ugly, where you will learn how to extract an image that's inside of another picture, and create an alpha plane, from that. In Alpha Planes Part 3: Things get less ugly, but ugly still, how to create an alpha plane for objects that have a lot details on their edges.
