The script below is a clothing server script. I am trying to make a part inside of the arms of character visible but it does not work. How can I fix this?
game.ReplicatedStorage.Events.ShirtEvent1.OnServerEvent:Connect(function(plr)
local char = plr.Character
local Button = game.StarterGui.Clothing.Shirts.BlackShirt
local q = BrickColor.new("Really black")
char["UpperTorso"].BrickColor = q
char["LeftUpperArm"].LeftUpperSleeve.BrickColor = q
char["LeftLowerArm"].LeftLowerSleeve.BrickColor = q
char["RightLowerArm"].RightLowerSleeve.BrickColor = q
char["RightUpperArm"].RightUpperSleeve.BrickColor = q
-----------------------
char["LeftUpperArm"].LeftUpperSleeve.Opacity = 1
char["LeftLowerArm"].LeftLowerSleeve.Opacity = 1
char["RightLowerArm"].RightLowerSleeve.Opacity = 1
char["RightUpperArm"].RightUpperSleeve.Opacity = 1
char.LowerTorso.BrickColor = q
end)

Transparency, not Opacity
There is nothing called "Opacity" in any property. It's called Transparency. You can set it from 0, to 1. 1 means invisible, 0 means visible. 0.5 means half opacity.
I tried opacity because i thought i saw someone use opacity, I tried using transparency and it still did not work
