I have 2 scene with 2 orbit controls, when the main scene rotates, aid scene should also rotate when the main scene zoom / pan, aid scene should not zoom / pan.
it seems like rotate moves camera's position and rotation, which was copied to aid scene's camera position / rotation. when zooming, rotation of xyz is not changed.
so, how can the aid scene copy only the rotation of the main scene but not the zooming / paning?
