Humanoid Description not applying dynamic head

[lamonLikeTinyGamer (Lamon)]

Hey developers!
I’ve been trying to make a dynamic character builder for my game using HumanoidDescriptions and other stuff, but for some reason Dynamic Heads never load…

Here’s the code:

local RStorage = game:GetService("ReplicatedStorage")
local InsertService = game:GetService("InsertService")

local CosmeticsData = require(RStorage.Databases.CosmeticsData)

-- To avoid pasting all 200 lines of code, just know that self.Wearing looks like this:
self.Wearing = {
	Accessories = {1,2},
	Bodyparts = {1,2},
	Clothing = {}
}

function NPC:BuildChar()
	
	local Char = script["BaseRig"..self.RigType]:Clone()
	
	-- Loading Accessories (IGNORE THIS PART)
	for _, id in self.Wearing.Accessories do
		local acc = CosmeticsData.Accessories[id]
		if not acc then warn("Could not find accessory with ID "..id); continue end
		
		local Model = nil
		
		if typeof(acc.ID) == "number" then
			Model = InsertService:LoadAsset(acc.ID):GetChildren()[1]
		else
			Model = RStorage.Assets.Accessories:FindFirstChild(acc.ID)
		end
		
		if Model == nil then continue end
		Model.Parent = Char
	end
	
	-- Loading Bodyparts (THIS IS WHAT DOESN'T WORK)
	local desc = Char.Humanoid.HumanoidDescription:Clone()
	
	for _, id in self.Wearing.Bodyparts do
		local acc = CosmeticsData.Bodyparts[id]
		if not acc then warn("Could not find accessory with ID "..id); continue end
		
		if typeof(acc.ID) == "number" then
			desc[acc.Type] = acc.ID
		end
		
	end
	
	Char.Parent = workspace
	Char.Humanoid:ApplyDescription(desc)
	Char.Parent = game.ServerStorage
	
	return Char
	
end

And this is the CosmeticsData script:

local Data = {
	Accessories = {
		{Name = "Sunglasses", Type = "Face", ID = 14400254687},	-- ID1
		{Name = "Tophat", Type = "Head", ID = "Tophat1"},		-- ID2
	},
	Bodyparts = {
		{Name = "testArm", Type = "LeftArm", ID = 27493648},	-- ID1
		{Name = "testHead", Type = "Head", ID = 3264},			-- ID2
	},
	Clothing = {}
}

return Data

Finally, here’s the base rig (left) and the end result (right):

As you can see, the face remains the same, but everything else loads in just fine…
Does anyone know what might be the problem?

Hi, sincere apologies for this bump but I was trying to solve this issue myself and found a solution that ended up working for me that I believe will also work for you!

I was trying to load a dynamic head via humanoid description onto a rig, however doing so would never load the head. What I discovered is that a rig and a player character have a very different structure, which could probably be why it wasn’t working.

Here’s my rig hierarchy:

And then here is my player hierarchy:

Long story short, I got a rig to apply the dynamic head by doing something like this:

local desc = Instance.new('HumanoidDescription')
desc.Head = 11748988354
local model = game:GetService('Players'):CreateHumanoidModelFromDescription(desc , Enum.HumanoidRigType.R15, Enum.AssetTypeVerification.Always)

model.Parent = workspace

Basically, I had to create a whole new model out of the humanoid description. Doing so created a hierarchy more similar to my player hierarchy, so I wonder if it has to do with the difference between a player model and rig generated with the rig creator. Either way, you can create a rig out of the description to get the head to work.

Here is my post if that is of any use to you!
