Chapter 13. Facial Animation Setup > Joint-Based Facial Animation Setup (Kila)

Joint-Based Facial Animation Setup (Kila)

The most obvious way to animate a character’s face is to use joints, because we are already employing them to animate the body. We simply place joints at certain places around the character’s face, which will then act like muscles, moving the vertices around and animating the face.

Where do we put facial joints to get the best facial expressions on Kila?

Image We need one to operate the mouth, opening and closing the jaw.

Image For the eyes, we’ll add joints that operate the eyelids.

Image Joints at several locations around the mouth will give movement to the lips, enabling the character to form words.

Image The eyebrows contribute a lot to facial expression, so we can add joints to move these as well.

Image If our budget allows, we can add the ability to animate the tongue.
