How can you use HasGamePass to make models visible and not visible? [UNSOLVED]

I was playing hole in the wall and that guy with the gamepass for the lounge gets invisible. I saw a guest jump on his head but he was not visible and i couldn't jump on him because i bought the pass and the guest didn't. I'm wondering how you can make a model or part visible to one player and the other player can't touch/see the part if he bought the pass. How can I do this? A wiki article would be appreciated. Not a script, since this site does not allow instant-scripts.(thats what I like to call them)

EDIT: I know about the PlayerHasPass. I'm wondering if I could create another base. Here's what I mean: Could it be possible to make a direct copy of the characters and their positions in the server, then teleport whoever has a pass to a seperate base with the fake characters moving like they are moving in the real character. But I think this is impossible to make the clones animate and move.
