Chapter 13. Facial Animation Setup > Blend Shapes Facial Animation Setup (Kila)

Blend Shapes Facial Animation Setup (Kila)

Blend shapes work by referencing the vertices from a duplicate of the main mesh. The duplicated vertices are edited to create a facial expression into which the main head will morph on command. Suppose the duplicate face is edited to represent an open mouth. Using the Blend Shape window, you can then tell the main face to gradually morph into the duplicate, making the character’s mouth open and close.

Depending on the system for which you are developing, the number of available blend shapes might be restricted, so always check with your manager first. Work with as few blend shapes as possible. In this section, we will work with just a few basic shapes, and you can add more if you have the budget to do so.
