Actor Root vs. Motion Root
The actor's root and the motion's root are the two knowledge bases you need to know before you start using AML ScriptEditor.

Let's image that when you have a doll inside a display box. In this case, the box would be the actor root and the doll is the motion root.
What will be the relationship between these two models?

 Actor Root  (define) Motion Root

The following are demos when each of the root is been dragged.

Only the Actor Root is applied. Only the Motion Root is applied. Both of the Actor root and the Motion root are both applied.

Note: When you have applied first animation clip to a character. Afterwards you want to apply second animation clip to the character. If you did not sample the motion root to the character, then when you apply the second animation clip to the character the motion root will be dragged to the original start point when the first animation clip starts its motion.
