I’ve been working on this issue for hours now and it’s extremely demoralizing 
This script makes it so players are invisible to each other.
local hide = true
local function checkPart(part)
for a,b in pairs(part:GetChildren()) do
checkPart(b)
end
if part:IsA("BasePart") or part:IsA("Decal") then
if hide == true then
part.Transparency = 1
end
if hide == false then
if part.Name ~= "HumanoidRootPart" then
part.Transparency = 1
else
part.Transparency = 0
end
end
end
end
local players = game:GetService("Players")
local localPlayer = players.LocalPlayer
function checkPartChar()
for i,v in pairs(players:GetPlayers()) do
if v ~= localPlayer then
local char = v.Character
if char then
checkPart(char)
end
end
end
end
game:GetService("RunService").RenderStepped:Connect(checkPartChar)
This code is part of a local script in StarterGui. It needs to be able to turn on and off. I have a separate piece of code that sets the hide variable to false and reruns the second function to check if hide is true or false.
This works miraculously, except for one thing. The HumanoidRootPart is still visible. Here is a picture of my friend standing in front of me;
As you can see the big gray part in his chest is the HumanoidRootPart, and it is clearly visible. The HumanoidRootPart is only visible on other players, your own is not visible. Anyone know how to fix this?
Thanks
