Anybody can help me with this?
thanks a lot

delete the animation channels defining rotation.

or make the animated object different from the rotating object. adding a few extra empties shouldnt affect performance.

-Root_Collision_Physics_Z-rotation
|    -Empty_Animated
    |    -Camera_X-rotation

yeah i did before with Euler X,Y,Z rotation keys lol now all fine

thanks a lot
