3ds bones rotation by unity

Hello everybody... I have a new question.


I would like to roteate the bones of the player (biped) by a "ghost object"..

I think I can figure it out with an image:



now... the idea is this:

Code (CSharp):

1.  
2. public void Task_BonesController_onstart()
3.        {
4.  
5.            // Create a main container
6.            GetVar.Dummy_Ribs = new GameObject("DummyOf["+GetVar.RibsBone.transform.name+"]");
7.            GetVar.Dummy_Ribs.transform.parent = GetVar.ModelsGroup.transform;
8.            GetVar.Dummy_Ribs.transform.rotation = GetVar.ModelsGroup.transform.root.rotation;
9.  
10.           // Create a fake bones
11.            GetVar.FakeBones_Ribs = new GameObject("FakeBonesOf["+GetVar.RibsBone.transform.name+"]");
12.            GetVar.FakeBones_Ribs.transform.parent = GetVar.Dummy_Ribs.transform;
13.            GetVar.FakeBones_Ribs.transform.position = GetVar.Dummy_Ribs.transform.position;
14.            GetVar.FakeBones_Ribs.transform.localRotation = GetVar.RibsBone.transform.localRotation;
15.  
16.        }
17.  

Code (CSharp):

1.  
2. public void Task_BonesController_onupdate()
3.        {
4.  
5.               //update fake bones equal to real bones
6.                GetVar.FakeBones_Ribs.transform.localRotation    = GetVar.RibsBone.transform.localRotation;
7.  
8.                //update position of dummy equale to bones position
9.                GetVar.Dummy_Ribs.transform.position = GetVar.RibsBone.transform.position;
10.  
11.                //update rotation of dummy whit the target
12.                Vector3 RibsToTargetDirection =
13.                new Vector3
14.                (
15.                    (GetVar.CameraTarget.transform.position.y - GetVar.Dummy_Ribs.transform.position.y),    //X//
16.                    (GetVar.CameraTarget.transform.position.x - GetVar.Dummy_Ribs.transform.position.x),    //Y//
17.                    (GetVar.CameraTarget.transform.position.z - GetVar.Dummy_Ribs.transform.position.z)       //Z//
18.                    
19.                );
20.                GetVar.Dummy_Ribs.transform.rotation = Quaternion.Lerp( GetVar.Dummy_Ribs.transform.rotation, Quaternion.LookRotation(RibsToTargetDirection), Time.deltaTime * GetVar.RibsSpeed );
21.  
22.                //update the bones equal fake bones
23.                GetVar.RibsBone.transform.localRotation = GetVar.FakeBones_Ribs.transform.localRotation;
24.  
25.  
26.       }
27.  

The proble is this:
I can see the fake bones roteate with the container ... but its values do not change and, therefore, nothing is transferred to the true bones.

What can I do then? Does anyone know some method?

thanks...
