Hello, so as you know robloxs fp cam(first person cam) isnt the height of game cameras. Currently, I have a camera bobbing system, and a raycasting offset system. But, the turning isnt so smooth. Is it possible to use tweens to turn the camera? Not for cutscenes, but for a regular game camera. Kinda like this: ROBLOX DOORS - Entity Concept: STALK | By Mekbok - YouTube Here is my current code:

local function initgamecam()
	onchartrans()
	local humrootpart = Character:WaitForChild("HumanoidRootPart")
	local hum:Humanoid = Character:WaitForChild("Humanoid")
	local tiltSpeedZ = 0.1
	local bobbingSpeed = 0.13
	cam.CameraSubject = Character.Humanoid
	cam.CFrame = Character.PrimaryPart.CFrame
	Player.CameraMode = Enum.CameraMode.LockFirstPerson
	cam.CameraType = Enum.CameraType.Custom
	local runService = game:GetService("RunService")
	--onchartrans()
	local lastcamcf = nil
	local tweenplaying = false
	camclipfix = RunService.RenderStepped:Connect(function()
		local ignore = RaycastParams.new()
		ignore.FilterType = Enum.RaycastFilterType.Exclude
		ignore.FilterDescendantsInstances = Character:GetChildren()
		local camray = workspace:Raycast(Character.char.Position, ((Character.char.CFrame + Character.char.CFrame.LookVector * 2) - Character.char.Position).Position.Unit)
		if camray then
			Character.Humanoid.CameraOffset = Vector3.new(0, 1, - (Character.char.Position - camray.Position).Magnitude)
		else
			hum.CameraOffset = Vector3.new(0,-0.5,-0.5)
		end
	end)
	
	local tilt = 0
	local sinValue = 0

	local function lerp(a, b, t)
		return a + (b - a) * t
	end

	local function calculateSine(speed, intensity)
		sinValue += speed 
		if sinValue > (math.pi * 2) then sinValue = 0 end
		local sineY = intensity * math.sin(2 * sinValue)
		local sineX = intensity * math.sin(sinValue)
		local sineCFrame = CFrame.new(sineX, sineY, 0)
		return sineCFrame
	end

	local previousSineX = 0
	local previousSineY = 0
	cambobconnect = runService.RenderStepped:Connect(function(dt)
		local movementVector = cam.CFrame:vectorToObjectSpace(humrootpart.Velocity / math.max(hum.WalkSpeed, 0.01))
		local speedModifier = (hum.WalkSpeed / 16)
		tilt = math.clamp(lerp(tilt, movementVector.X * tiltSpeedZ, 0.1), -0.05, 0.1) / 2

		local sineCFrame = calculateSine(bobbingSpeed * speedModifier, movementVector.Z * speedModifier)
		local lerpedSineX = lerp(previousSineX, sineCFrame.X, 0.1)/2
		local lerpedSineY = lerp(previousSineY, sineCFrame.Y, 0.1)

		cam.CFrame *= CFrame.Angles(0, 0, tilt) * CFrame.new(lerpedSineX, lerpedSineY, 0)
		previousSineX = lerpedSineX
		previousSineY = lerpedSineY
	end)
	
end

Heres my character layout:

Thanks!
