Animating breathing and jaw animations

While Character Animator can lip-sync by switching mouth poses based on phonemes, we can enhance this effect even further by adding a Nutcrack Jaw behavior. This will allow the jaw to drop based on what the mouth is doing. As with the eyelids, this is an optional feature. We will also add a Breathing behavior for further exploration:

1. Click on Mouths inside of 3/4th Head.
2. Using the handle tool, click and add a handle below the mouth:

3. On the Tags panel, click on the jaw icon to define the layer.
4. At the bottom of the Tags panel is a plus sign next to Behaviors. Click on the plus sign and choose Nutcracker Jaw from the list:

5. Next, click on the Body layer and add a handle in the middle...
