How do you invert an X Axis of a Viewport frame?

Hello!

I am currently trying to make a Viewport frame which acts as a mirror. This does work, however the reflection is flipped the wrong way. Is it possible to invert the X axis?

I have a LocalScript in the SurfaceGUI with the Viewport frame for the mirror:

local RunService = game:GetService("RunService")
local UserInputService = game:GetService("UserInputService")
local instance,newRay = Instance.new,Ray.new
local V2,V3,CF,UDIM2 = Vector2.new,Vector3.new,CFrame.new,UDim2.new
local Insert,Rand,ABS = table.insert,math.random,math.abs
local Player = game:GetService("Players").LocalPlayer
local Character	= Player.Character or Player.CharacterAdded:Wait()
local ViewportFrame = script.Parent.ViewportFrame
local ReflectionCamera	= workspace.ReflectionCam
local Screen = workspace.Screen
local Camera = instance("Camera")
	Camera.CFrame = ReflectionCamera.CFrame
	ViewportFrame.CurrentCamera	= Camera
ReflectionCamera:GetPropertyChangedSignal("CFrame"):Connect(function()
	Camera.CFrame = ReflectionCamera.CFrame
end)



local DEG = math.deg
local function inFOV (p0, p1)
    local X1, Y1, Z1 = p0:ToOrientation()
	local CF = CF(p0.p, p1.p)
	local X2, Y2, Z2 = CF:ToOrientation()
    return V3(DEG(X1-X2), DEG(Y1-Y2), DEG(Z1-Z2))
end

local Humanoids = {}
local Parts	= {}

local function RenderVersion(Object)
	local Descendants = Object:GetDescendants() 
	for i = 1, #Descendants do
		local Children = Descendants[i]
		if (Children:IsA("Script") or Children:IsA("Sound") or Children:IsA("ManualWeld") or Children:IsA("BasePart"))then
			Children:Destroy()
		end
	end
	return Object
end
	
local function RenderHumanoid(Model, Parent, MainModel)
	local ModelParts = Model:GetChildren()
	for i = 1, #ModelParts do
		local Part = ModelParts[i]
		if not Part:IsA("Script") then
			local Arch = Part.Archivable
				Part.Archivable	= true
			local RenderClone = Part:Clone()
			Part.Archivable	= Arch
		
			if Part:IsA("MeshPart") or Part:IsA("Part") then
				PartUpdater = RunService.Heartbeat:Connect(function()
					if Part then
						RenderClone.CFrame = Part.CFrame
					else
						RenderClone:Destroy()
						PartUpdater:Disconnect()
					end
				end)
			elseif Part:IsA("Accoutrement") then
				PartUpdater = RunService.Heartbeat:Connect(function()
					if Part then
						RenderClone.Handle.CFrame = Part.Handle.CFrame
					else
						RenderClone:Destroy()
						PartUpdater:Disconnect()
					end
				end)
			elseif Part:IsA("Script") then
				RenderClone:Destroy()
			end
			RenderClone.Parent = Parent
		end
	end
end

local function RenderObj(Obj, Parent, Map)
	local ObjParts = Obj:GetChildren()
	for i = 1, #ObjParts do
		local Part = ObjParts[i]
		if Map then
			if Part:IsA("BasePart") or Part:IsA("Model") or Part:IsA("Folder") then
				local Arch2	= Part.Archivable
					Part.Archivable	= true
				local RenderClone = RenderVersion(Part:Clone())
				Part.Archivable	= Arch2
				RenderObj(Part, RenderClone, Map)
				RenderClone.Parent = Parent
			end
		else
			if not Part:IsDescendantOf(workspace.Map) and Part ~= workspace.Map then
				if not Parts[Part] and not Humanoids[Part] then
					if Part:IsA("Model") or Part:IsA("Folder") then
						if Part:FindFirstChildWhichIsA("Humanoid", true) then
							Humanoids[Part] = true
								
							local ModelClone = instance("Model")
								ModelClone.Name	= Part.Name
															
							RenderHumanoid(Part, ModelClone,ModelClone)
								ModelClone.Parent = Parent
						else
							local ModelClone = instance("Model")
								ModelClone.Name	= Part.Name
							
							Part.ChildAdded:Connect(function(Child)
								wait() 
								RenderObj(Part, ModelClone, Map)
							end)
							
							RenderObj(Part, ModelClone, false)
								ModelClone.Parent = Parent
						end
					elseif Part:IsA("BasePart") then 
						if Part ~= workspace.Terrain then
							Parts[Part] = true
							local Arch3	= Part.Archivable
								Part.Archivable	= true
							local RenderClone = RenderVersion(Part:Clone())
							Part.Archivable	= Arch3

							Part.ChildAdded:Connect(function(Child)
								wait()
								RenderObj(Part, RenderClone, Map)
							end)
							
							local LastCF, LastTP, LastColor, LastSize, LastMat = Part.CFrame,Part.Transparency,Part.Color,Part.Size,Part.Material
		
							spawn(function()	
								while wait() do
									if Part then
										local FOV = inFOV(Camera.CFrame,Part.CFrame)
										if (ABS(FOV.Y+FOV.X) *2 ) < (Camera.FieldOfView + 40) then 
											if LastCF ~= Part.CFrame then
												LastCF = Part.CFrame 
												RenderClone.CFrame = Part.CFrame
											end
											if LastTP ~= Part.Transparency then
												LastTP = Part.Transparency
												RenderClone.Transparency = Part.Transparency
											end
											if LastColor ~= Part.Color then
												LastColor = Part.Color
												RenderClone.Color = Part.Color
											end
											if LastSize ~= Part.Size then
												LastSize = Part.Size
												RenderClone.Size = Part.Size
											end
											if LastMat ~= Part.Material then
												LastMat = Part.Material
												RenderClone.Material = Part.Material
											end
										end
									else
										RenderClone:Destroy()
										Parts[Part] = false
										break
									end
								end
							end)
							RenderObj(Part,RenderClone,Map)
							RenderClone.Parent = Parent
						end
					end
				end
			end
		end
	end
end


wait(1)


local MapClone = Instance.new("Mode\l")
		MapClone.Name = 'Map'
	RenderObj(workspace.Map, MapClone,true)
		MapClone.Parent = ViewportFrame
RenderObj(workspace, ViewportFrame)
workspace.ChildAdded:Connect(function(Child)
	wait()
	RenderObj(workspace, ViewportFrame)
end)

If I could get some help with this, it would be great. Thanks!
