How can I make the script show the character entirely?

I have this camera script, that shows the player in a special third-person perspective. The script IS working, but for some reason, I can't make the Accessory part meshes visible. I tried it multiple times with different approaches, but nothing works. Can you help me with my issue? The script:

c = workspace.CurrentCamera

player = game.Players.LocalPlayer
char = player.Character or player.CharacterAdded:wait()
humanoid = char:WaitForChild("Humanoid")


player.CameraMaxZoomDistance = 0.5
c.FieldOfView = 90 
humanoid.CameraOffset = Vector3.new(1,0.2,1)

function lock(part)
    if part and part:IsA("BasePart") then
        part.LocalTransparencyModifier = part.Transparency
        part.Changed:connect(function (property)
            part.LocalTransparencyModifier = part.Transparency
        end)
    end
end

for _,v in pairs(char:GetChildren()) do
    lock(v)
end

char.ChildAdded:connect(lock)


c.Changed:connect(function (property)
    if property == "CameraSubject" then
        if c.CameraSubject and c.CameraSubject:IsA("VehicleSeat") and humanoid then
            c.CameraSubject = humanoid;
        end
    end
end)

(P.S. This script is not mine! Thanks in advance!)
