First off, Armature (bone) that you create must have Parent – child relationship to work together as a unit. And, the Armatures are set as a Parent to the object (skin) to “link” its animation movement to drive the object movement. Then, you animate the Armature.

so are you sort of saying that i have t move the parent to move other bones
