Smooth Camera Spring Glitching

I’m writing a smooth first person camera system like DOORS for my game, and wanted to use Quenty’s spring module instead of lerps to make my camera extra smooth. (the way the camera will slightly overshoot the mouse but correct itself smoothly). I got it to work perfectly with the camera position but the camera direction keeps glitching. I think it’s because the spring always tries to take the shortest route possible to the target direction, which is sometimes the opposite direction the mouse was actually moving. Here’s the code:

local RunService = game:GetService("RunService")
local UIS = game:GetService("UserInputService")
local Players = game:GetService("Players")

local Enabled = script:WaitForChild("CamEnabled")


local Camera = workspace.CurrentCamera

local ZERO_VECTOR = Vector3.new()

local SpringModule = require(script:WaitForChild("Spring"))
local CamPosSpring = SpringModule.new(ZERO_VECTOR)
CamPosSpring.Speed =  40
CamPosSpring.Damper = .3

local CamDirSpring = SpringModule.new(ZERO_VECTOR)
CamDirSpring.Speed = 30
CamDirSpring.Damper = .8

local LocalPlayer = Players.LocalPlayer
local Character = LocalPlayer.Character or LocalPlayer.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid"):: Humanoid
local RootPart = Character:WaitForChild("HumanoidRootPart"):: Part


local function UpdateCameraMisc(enabled)
	UIS.MouseIconEnabled = not enabled

	if enabled == false then
		Camera.CameraType = Enum.CameraType.Custom
		if UIS.MouseBehavior == Enum.MouseBehavior.LockCenter then
			UIS.MouseBehavior = Enum.MouseBehavior.Default
		end
	else
		Camera.CameraType = Enum.CameraType.Scriptable
		UIS.MouseBehavior = Enum.MouseBehavior.LockCenter
	end
end

local UpdatedTransparency = false

local function SetBodyTransparency(transparency)
	if not Character or UpdatedTransparency then
		return
	end
	
	UpdatedTransparency = true

	for _, v in pairs(Character:GetDescendants()) do
		if v:IsA("BasePart") then
			v.LocalTransparencyModifier = transparency
		end
	end
end


local CameraDirection = Vector2.new()
local Sensitivity = 0.3
local MaxLookRange = 85

local TargetCamPos, TargetCamDir = Camera.CFrame.Position, Vector3.new(Camera.CFrame:ToOrientation())

local function UpdateTargetValues()
	CameraDirection -= UIS:GetMouseDelta() * Sensitivity
	CameraDirection = Vector2.new(CameraDirection.X%360, math.clamp(CameraDirection.Y, -MaxLookRange, MaxLookRange))
	
	TargetCamPos = RootPart.Position + Vector3.new(0, 1.5, 0)
	TargetCamDir = Vector3.new(math.rad(CameraDirection.Y), math.rad(CameraDirection.X), 0)
end

RunService.RenderStepped:Connect(function()
	SetBodyTransparency(Enabled.Value and 1 or 0)
	UpdateCameraMisc()
	UpdateTargetValues()
	
	Camera.CFrame = CFrame.new(CamPosSpring.Position) * CFrame.fromOrientation(CamDirSpring.Position.X, CamDirSpring.Position.Y, 0)
	CamPosSpring.Target = TargetCamPos
	CamDirSpring.Target = TargetCamDir
end)

If anyone could help, I would greatly appreciate it.
