Is it possible to make a part only visible to a play that owns a certain gamepass? If so, how can I achieve this? Does anyone have links to a ROBLOX wiki about this?
There are two ways of doing this. If your game is FilteringEnabled you can just insert the part with a LocalScript and it will show up for that player only.
If it isn't FilteringEnabled you would simply check if the user has the gamepass and then put the part into workspace.CurrentCamera;
I hope this helped. If it did please accept this as the answer. If it didn't feel free to ask questions. (I didn't include any code because here on scripting helpers we do not just give out code. I am telling you methods on how to do it and letting you figure it out from there. Good luck!)
