Shift lock doesn't work with current camera script

[RCW3993 (rcw)]

I made this smooth camera script

-- Services
local rS = game:GetService("RunService")
local tS = game:GetService("TweenService")

-- Variables
local camera = game.Workspace.CurrentCamera
local root = script.Parent:WaitForChild("HumanoidRootPart")
local cameraPart = Instance.new("Part")
local newPos

-- Script
cameraPart.Anchored = true
cameraPart.CanTouch = false
cameraPart.CanCollide = false
cameraPart.Parent = game.Workspace
cameraPart.CFrame = CFrame.lookAt(root.CFrame.Position + Vector3.new(0, 7, 12), root.Position)

camera.CameraType = Enum.CameraType.Scriptable

rS.PostSimulation:Connect(function(dt)
	cameraPart.Position = cameraPart.Position:Lerp(root.Position + Vector3.new(0, 7, 12), dt * 5)
	camera.CFrame = cameraPart.CFrame
end)

But I can’t shift lock with the script enabled. I think it’s because I set the camera type to scriptable. I would appreciate it if someone could help me find a way to work around this!

How to Add "Weight" to the Camera [Camera Tutorial]

Here is a simple tutorial on how to add weight to the camera so that it drags behind the character as they move instead of being rigidly attached to them. This works by setting the camera subject to an invisible part which attempts to reach the character through linear interpolation. This has the effect of the dragging the camera behind the character as they move. One benefit to this is that it has minimal conflict with usual camera function and you can do things like pivot the camer…

This tutorial covers shift lock too.
