How do you make a character rotate their heads towards a point?

Hello there.

I'm trying out Motor6Ds to make my NPC's Head face towards me.

Here is my script:

local runService = game:GetService("RunService")
local NPC = script.Parent

function move()
	local neck = NPC.Head.Neck -- 'Neck' is a Motor6D
	local target = workspace.NoBootAvailable.Head
	local lookAt = CFrame.new(neck.C1.p, target.CFrame.p)
	
	neck.C1 = lookAt
end

runService:BindToRenderStep(move)

The problem is that the NPC's Head wont face towards me. Is there any reason why?

Luckily I've been playing around with Motor6Ds and I've done something like this recently. You are very close to making this work but, what I found out about rotating parts(motor6Ds) of a already rotating model(NPC) is the orientation of the vector you want the limb to point to gets really miss lead with all these different oriented parts/models. So I had to use "toObjectSpace" to fix the problem. I don't completely understand it but, what I can figure is that it puts the vector into it's own space instead of the world space. The line below is what I did to fix my problem hopefully it will fix yours. If not, try playing around with the function.

local lookAt = (NPC.HumanoidRootPart.CFrame:toObjectSpace(target.CFrame.p))

sorry for the ugly explanation, but I hope it helps :)

Still no luck, even if I convert it to World Space.
