hi guys! i´ve a problem which is driving me crazy… i´m trying to rotate a torso which should be seen by all clients. the RPC version is pretty working but at high costs of kb/s (3,5k) while the the character´s amount of kb/s ist just 0.400… so i tryed to use OnSerializeNetworkView(…) but no data is send. can someone tell me what i´m doing wrong? 
using UnityEngine;
using System.Collections;
public class player_TorsoRotation : MonoBehaviour {
public Transform torso;
private float spin = 0;
public float sensitivityX = 45f;
public float smooth = 2f;
Quaternion torsoRotationTemp;
Quaternion temp;
Vector3 tempVec = Vector3.zero;
void Start(){
if(networkView.isMine){
torso.rotation = temp;
temp = Quaternion.Euler(tempVec);
}
}
void Update(){
if(networkView.isMine) {
if(Input.GetMouseButton(1)){
spin += Input.GetAxis("Mouse X") * sensitivityX;
spin = Mathf.Clamp(spin, -sensitivityX, sensitivityX);
}
else if(!Input.GetMouseButton(1)){
spin = 0f;
//torso.rotation = temp;
}
if(torso.rotation != temp spin >= 0.5f || torso.rotation != temp spin <= 0.5f){
torsoRotationTemp = Quaternion.Slerp(torsoRotationTemp, Quaternion.Euler(0, spin,0), Time.deltaTime * smooth);
torso.rotation = transform.rotation * torsoRotationTemp;
//networkView.RPC("setTorsoRotation2", RPCMode.All, torso.rotation);
}
}
}
void OnSerializeNetworkView(BitStream stream, NetworkMessageInfo info) {
// Always send transform (depending on reliability of the network view)
if (stream.isWriting)
{
Quaternion rot = torso.rotation;
stream.Serialize(ref rot);
}
else
{
Quaternion rot = Quaternion.identity;
stream.Serialize(ref rot);
torso.rotation = rot;
}
}
[RPC]
void setTorsoRotation2 ( Quaternion rota ){
//Debug.Log("setAnimationState called with index:"+aStateIndex);
torso.rotation = rota;
//torso.rotation = transform.rotation * torso.rotation;
//charMesh.animation.CrossFade(animations[aStateIndex], 0.2f);
//Debug.Log(rota);
}
}
