Adding custom UGC head to dummy via script not working

[QNCL0 (qnc)]

I want to change a r6 dummy’s head to a UGC one through humanoiddescriptions, and upon trying it out, nothing happens. The dummy’s head is still default. I tried using the bundleID, head ID, and asking around but nobody could help me fix it. Here’s the code

local desc = script.Parent:GetAppliedDescription()
desc.HairAccessory = ""
desc.HatAccessory = ""
desc.WaistAccessory = ""
desc.FrontAccessory = ""
desc.FaceAccessory = ""
desc.BackAccessory = ""
desc.Shirt = ""
desc.Pants = ""
desc.Face = ""
desc.Head = "" -- Head ID here
script.Parent:ApplyDescription(desc)

for i,v in pairs(script.Parent.Parent:GetChildren()) do
	if v:IsA("MeshPart") or v:IsA("Accessory") or v:IsA("Part") then
		local clickDetect = Instance.new("ClickDetector", v)
		clickDetect.CursorIcon = "rbxassetid://10150438823"
		clickDetect.MouseClick:Connect(function(player)
			game:GetService("ReplicatedStorage").productList:FireClient(player, script.Parent.Parent)
		end)
	end
end

For reference, I’m trying to put the Lamp head on a dummy.

Make the default head invisible and turn off the face.

Then add the accessory.

It’s a head I’m trying to add, not an accessory. Making the head invisible would pretty much be removing the head altogether instead of making the custom head appear.

I’ve solved the issue, the dummy needs to be R15 in order to have the head appear.
Edit: To keep the R6 look I was going for, I used ellieflopper’s R15 model that looks like R6.
