If your game uses many real-time cut-scenes, chances are your character will need facial animation. The eyes play a huge part in acting; we are all drawn to the eyes when we interact with people.
Eyes are relatively easy to construct; all you need to do is create a sphere and optimize it slightly. You may have noticed that our model already has some spheres where the eyes should be. These were used earlier to create the eyelids, and we did not delete them. To demonstrate how to create the eyes, we will remove these spheres and start from scratch.
There we have it; the eyes are done (Figure 4.39). Feel free to save at this point.
