Basic Clay Animation Tips
Now that you've completed the art and text, it's time to move on to animation. Timing, acting, lip-sync, and gags are some of the foundations. How to animate mouths in clay is something that isn't covered in any animation book
I've seen, so I'll attempt to describe how to make a mouth in clay. Step one is to sketch out the features of your characters' heads. The next step is to hollow out a large hole where the mouth will be located. If you're making
a white-teeth character on a green background, for example, the whitened clay around his teeth will gradually turn green from his lips outward. So, make your protagonist.
One method is to take the color of your characters' facial clay and mix it with a darker hue and put it in their back molars before adding lips to your hollowed-out face. It looks more natural, and the lips stand out a little more
as a result. Finally, apply lipstick over the teeth.
When you move the lip, a common technique is to make a wedge-shaped chunk of clay out of the top lip and close the gap by raising the lip edge. Because you don't have to re-sculpt the lip edge for each movement, this prevents the
lips from flashing (Strobing effect). Add clay to the lip's outer edge when you form the mouth in the shape of an "O." You carefully cut off the outstretched lips after changing form back to a normal mouth position so you may
reuse them for the next "O" shaped lips in your animation sequence.
Just as real people do, add a few more attributes to make your animated jaw look more natural. To accomplish this, cut a line straight back from the center of the lips all the way down to just beneath the ears and pull down your
jaw. Then smother over both cheek slits with a small layer of clay that has been smoothed out.
