Third Party [Photon] Hide an child object for other players inside an photonView object

I am currently making a school project and I was wondering on how I could hide a child gameobject for the other players insdie an photonView object. What is the best/simplest way to fix this?

Edit: To clarify this, I want to make the gameobject just to show to the client and not the whole server.

 

I may be misunderstanding you but:
If you need a new, local object, simply instantiate it locally. Without a PhotonView and just using Object.Instantiate.
