AddMixingTransform does not work, why?

Hello there, would like to know whats wrong with my script. I tried to used AddMixingTransform for my character. Would like to make my character idle and wave at the same time. But when I used AddMixingTransform it just move my character left hand to wave but the other body part does not move at all. what is that.

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class NewBehaviourScript : MonoBehaviour {
6.    
7.     public GameObject upin;
8.     public Transform shoulder;
9.    
10.     // Use this for initialization
11.     void Start () {
12.         upin.animation ["wave"].AddMixingTransform (shoulder);
13.         upin.animation ["wave"].layer = 5;
14.     }
15.  

and when I do it like below it does not read the wave animation. it just play the idle.

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class NewBehaviourScript : MonoBehaviour {
6.    
7.     public GameObject upin;
8.     public Transform shoulder;
9.    
10.     // Use this for initialization
11.     void Start () {
12.         upin.animation ["wave"].AddMixingTransform (shoulder);
13.         upin.animation ["wave"].layer = 5;
14.     }
15.    
16.     // Update is called once per frame
17.     void Update ()
18.     {
19.         upin.animation.Play ("idle");
20.     }
21. }
22.  
23.  

what did i do wrong.

 

Do you need to add true to the call, for recursive? Or is it true by default

And why not just use mecanim, this is pretty much what avatar masking does

 

yup i need to put a true / false statement..solved it, dont have mecanim because i on ly have unity 3.5.
