I got a new problem

Options
Hello there, I got a new problem in my fps zombie game.
The problem is that the second player can't see the first player.

I tried many times to fix it, but it fails.

I will send my current scripts of my game:

PlayerController.cs : https://pastebin.com/b7G5KjYR
PlayerMotor.cs : https://pastebin.com/aPiiM9ER
GameManager.cs : https://pastebin.com/kVNQtbgc

I saw many questions from other users, either the question/version is too old or the code doesnt work (maybe because of the old question/version)
