Making players invisible to each other?

Both of these scripts didn't do what I wanted

for i,v in pairs(game.Players:GetChildren) do
 for ai,va in pairs(v.Character:GetChildren() do
if va:IsA("BasePart") or va:IsA("MeshPart")
va.Transparency = 1
end
end
end

-

local Camera = game.Workspace.CurrentCamera
    Player.Character.Parent = Camera

Any other ways I could "temporarily" make players invisible to each other and so they could only see their own character?

Thanks!
