Breathing Animation

With this model, I used morph targets to animate the breathing motions rather than completely trying to key animate every motion. This works a lot better than trying to manually animate simple animations such as breathing, blinking, or subtle facial expressions.

If you look closely, you will see the chest move out with the neck inhaling and cheeks puffing. I forgot the video doesn't loop on its own, so you may have to view it several times to see the subtleties of the animation.
