Add Character Control and Animation to Our Hero/Heroine - Unity 4 Game Development - page 252

In the last setup, we tell this clip to be a looping animation and set all the trans-
forms (rotation, Y position, and XZ position) to use Baked into Pose . This will
make sure that all the root transforms will be constant and delta root rotation, Y
position, and XZ position equal zero. This means that our character, gameOb-
ject , will not rotate or move at all by AnimationClip .
