Facial Motion and Controls - Animating with Blender: How to Create Short Animations from Start to Finish - page 177

● Click the Add Driver button in the Ipo Editor's Transform Properties panel.
● Enter the name of the character's control armature in the OB: fi eld that appears (Figure 10.30).
● Change the setting on the right side of the panel from Object to Pose .

● Enter the name of the bone that will act as the animation controller for the shape into the new BO: fi eld that
appears (Figure 10.31).

● Now you have to decide which aspect of the bone will control the shape: rotation, location, or scale? In the
example, Loc Y has been chosen, meaning that vertical motion of the bone will control the shape. It's best
to choose something that makes sense to you when deciding which type of transformation to use. If the
shape twists the nose to one side or another, you will probably want to choose a rotation along an axis that
corresponds to the actual motion. For shapes that make cheeks puff out, you may want to choose a scaling
transformation. Technically it doesn't have to relate, but it will certainly make the controls more intuitive.
● With the mouse over the Ipo Editor , press the I-key and accept the Default one-to-one mapping
from the Insert Curve menu that pops up (Figure 10.32).
