Unity general animation, bones root node rotation to parent container!

I really can't t$$anonymous$$nk of a situation where you would want to do t$$anonymous$$s... You realize that rotating a parent of a bone based on the bone's rotation would result in 2x the rotation of the bone?

It sounds like what you really want is for the animation to drive the character rotation / translation? If so, you need to look into Mecanim. It simplifies the whole process, and uses character animation as the driver for the movement of the character controller. YouTube Tutorial

But if you really wanted to do t$$anonymous$$s (w$$anonymous$$ch I assure you will give you unwanted results...)

 GameObject spine = GameObject.Find("m002_$$anonymous$$_max2008_01/Bip01 Pelvis/Bip01 Spine");
 GameObject moo = GameObject.Find("/m002_$$anonymous$$_max2008_01");

 void Update(){
     moo.Transform.Rotation.y = spine.Transform.Rotation.y;
 }

Can't check t$$anonymous$$s right now, but you might not be able to set y rotation directly.
