Parts not aligning when copying players movement

I’m trying to make an npc which copies all your movements, however the hair accessory isn’t aligning to where it should be, and when I tried adjusting it with Vector3.new it just wasn’t consistent and would sway from side to side (the vector3.new edit isn’t showcased in the video above)

local RNS = game:GetService("RunService")
local plr = game.Players.LocalPlayer
plr.CharacterAdded:Wait()
local char = plr.Character

local npc = game.Workspace:WaitForChild("NoahFollow")
for i,part in npc:GetChildren() do
	if part:IsA("MeshPart") then
		if part.Name ~= "Head" then
			part.Anchored = true
			part.CanCollide = true
		end
	end
end
RNS.RenderStepped:Connect(function(delta)
	local head =char:FindFirstChild("Head").Position
	--local hair=head+Vector3.new(0,0.25,-0.25)
	local HRP=char:FindFirstChild("HumanoidRootPart").Position
	local LUA= char:FindFirstChild("LeftUpperArm").Position
	local LLA = char:FindFirstChild("LeftLowerArm").Position

Instead of searching for each part manually, make a loop and set the CFrames:

local RNS = game:GetService("RunService")
local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()

local npc = workspace:WaitForChild("NoahFollow")

for _, part in npc:GetChildren() do
	if part:IsA("MeshPart") and part.Name ~= "Head" then
		part.Anchored = true
		part.CanCollide = true
	end
end

local bodyPartNames ={
	"Head", "HumanoidRootPart", "LeftUpperArm", "LeftLowerArm", "LeftHand", 
	"LeftUpperLeg", "LeftLowerLeg", "LeftFoot", "RightUpperArm", "RightLowerArm", 
	"RightHand", "RightUpperLeg", "RightLowerLeg", "RightFoot", "LowerTorso", "UpperTorso"
}

RNS.RenderStepped:Connect(function(delta)
	-- build cframe dictionary
	local cframes = {}
	
	for _, partName in bodyPartNames do
		local part = char[partName]
		cframes[partName] = part.CFrame
	end
	
	-- apply cframes after wait
	task.wait(1.5)
	
	for _, partName in bodyPartNames do
		local part = npc[partName]
		part.CFrame = cframes[partName]
	end
	
	-- custom offset for hair
	npc["Pal Hair"].CFrame = cframes.Head * CFrame.new(0, 0.25, -0.25)

	local distance =(char.HumanoidRootPart.Position - npc.HumanoidRootPart.Position).magnitude

	if distance < 2 then --makes the npc invisible when near player
		local transparency = 1 - (distance/2)
		npc.Head.face.Transparency = transparency
		for _, part in npc:GetChildren() do
			if part:IsA("MeshPart") then
				part.Transparency = transparency
			elseif part:IsA("Accessory") then
				part.Handle.Transparency = transparency
			end
		end
	else
		npc.Head.face.Transparency = 0
		for _, part in npc:GetChildren() do
			if part:IsA("MeshPart") then
				part.Transparency = 0
			elseif part:IsA("Accessory") then
				part.Handle.Transparency = 0
			end
		end
	end
end)

You should also apply the hair offset via cframe so the direction is relative/local instead of global.

This works! I appreciate the help, although for some reason the hair didn’t need to be offset
