Accessing a Parent's PhotonID from a child's script

When I access my child object in question's renderer property, it affects all objects accessing the server that fall under the property of (isMine). When I update the child's renderer ALL client's corresponding mesh' access the same script.

There must be a way to find the current client's child mesh of controlled parent so I can modify THIS object's child's renderer from ALL clients to see what other players are doing
