Player character model is rotating inconsistently in First Person Camera Mode

[Ribasu]

I would like to have a player spectate another. I created the following demo to showcase a problem that I am having.

This code sends player 1’s camera to player 2, so that player 2 can see what player 1 is seeing. Both players are in First Person Mode camera. It seems like the character model of both players is not moving in the same orientation. More specifically when player 1 (right screen in gif) moves left or right, the character faces forward, however in player 2’s (left screen in gif) screen turns around as if the character has turned towards the moving direction. This is most evident by the tool/shadow being inconsistent for both players. Refer to the following gif and code.

-- ServerScriptService
game.ReplicatedStorage.PlayerCamera.OnServerEvent:Connect(function(player, cframe)
	game.ReplicatedStorage.PlayerCamera:FireClient(
		game.Players:WaitForChild("Player2"),
		cframe
	)
end)

-- StarterPlayer.StarterPlayerScripts
local localPlayer = game.Players.LocalPlayer
local camera = workspace.CurrentCamera

local function SetFirstPersonMode()
	camera.CameraType = Enum.CameraType.Attach
	localPlayer.CameraMode = Enum.CameraMode.LockFirstPerson	
end

SetFirstPersonMode()
local tempCframe = nil

if localPlayer.Name == "Player1" then
	print('Walk')
	game:GetService("RunService").RenderStepped:Connect(function()
		game.ReplicatedStorage.PlayerCamera:FireServer(workspace.CurrentCamera.CFrame)
	end)
elseif localPlayer.Name == "Player2" then
	print('Spectate player 1')
	camera.CameraSubject = workspace:WaitForChild("Player1")

	game.ReplicatedStorage.PlayerCamera.OnClientEvent:Connect(function(cframe)
		tempCframe = cframe
	end)	
	
	game:GetService("RunService").RenderStepped:Connect(function()
		workspace.CurrentCamera.CFrame = tempCframe
	end)
end

Solved by setting humanoid.AutoRotate property to false on the spectator.
