In this lesson you learned how to:

• Set driven keys to link one attribute’s values to another.

  A driven attribute is not directly affected when you play the animation. It is linked to a driving attribute’s value, not animation time. However, you can use regular animation keys, expressions, motion paths, or other techniques to animate the driving attributes. This indirectly animates the driven attribute.

You may find the following notes helpful when using Set Driven Key:

• You can set driven keys to control a driven attribute with multiple driving attributes. For instance, you can have a muscle bulge when an elbow rotates, and have the bulge increase when the wrist rotates.
