How would I increase the size of an NPC along with it's accessories?

I want to increase the size of my NPCs but still make them animatable and keep their accessories in the right position/size. How would I do this?

Note: I’m not tweening the size or anything. I just want to change it to a bigger value.

There are different ways to achieve this depending on whether you are using R6 or R15 rigs. Which are you using?

I’d recommend posting stuff like this in #help-and-feedback:scripting-support.

Edit:
NVM, for NPCs you can use Humanoid:ApplyDescription and HumanoidDescription HeightScale/HeightScale/DepthScale/etc. You can find those properties here:

local function ApplyScaling(Character : Model, Scale : number)
	local Motors = {}

	table.insert(Motors, Character.HumanoidRootPart.RootJoint)
	for i,Motor in pairs(Character.Torso:GetChildren()) do
		if Motor:IsA("Motor6D") == false then continue end
		table.insert(Motors, Motor)
	end
	for i,v in pairs(Motors) do
		v.C0 = CFrame.new((v.C0.Position * Scale)) * (v.C0 - v.C0.Position)
		v.C1 = CFrame.new((v.C1.Position * Scale)) * (v.C1 - v.C1.Position)
	end


	for i,Part in pairs(Character:GetChildren()) do
		if Part:IsA("BasePart") == false then continue end
		Part.Size *= Scale
		for _,Attachment in pairs(Part:GetChildren()) do
			if Attachment:IsA("Attachment") == false then continue end
			Attachment.Position *= Scale
		end
	end

	
	for i,Accessory in pairs(Character:GetChildren()) do
		if Accessory:IsA("Accessory") == false then continue end

		Accessory.Handle.AccessoryWeld.C0 = CFrame.new((Accessory.Handle.AccessoryWeld.C0.Position * Scale)) * (Accessory.Handle.AccessoryWeld.C0 - Accessory.Handle.AccessoryWeld.C0.Position)
		Accessory.Handle.AccessoryWeld.C1 = CFrame.new((Accessory.Handle.AccessoryWeld.C1.Position * Scale)) * (Accessory.Handle.AccessoryWeld.C1 - Accessory.Handle.AccessoryWeld.C1.Position)

		if Accessory.Handle:FindFirstChildOfClass("SpecialMesh") then
			Accessory.Handle:FindFirstChildOfClass("SpecialMesh").Scale *= Scale
		end
	end
end
