Rain Drop Effect Disappears When Looking In The Ground

so I made a script that detects if the player has a roof on their head but for some reason if I go outside and look at the ground, the rain drop effect disappears or gets disaled for some reason

heres the code

local MapFolder = workspace.MapFolder

local Player = game:GetService("Players").LocalPlayer
local PlayersUI = Player.PlayerGui:FindFirstChild("PlayersUI")

local RainSoundGroup = game:GetService("SoundService"):FindFirstChild("__RainSoundGroup")
local TweenService = game:GetService("TweenService")
local tInfo1 = TweenInfo.new(0.46, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut, 0, false)

local RainSoundExit = TweenService:Create(RainSoundGroup.RainSound, tInfo1, {Volume = 0.3})
local VignetteExit = TweenService:Create(PlayersUI.Vignette, tInfo1, {ImageColor3 = Color3.new(0, 0, 0)})

local RainSoundEnter =     TweenService:Create(RainSoundGroup:FindFirstChild("RainSound"), tInfo1, {Volume = 0.1})
local VignetteEnter = TweenService:Create(PlayersUI:FindFirstChild("Vignette"), tInfo1, {ImageColor3 = Color3.new(255, 255, 255)})

local RainModule = require(script.Parent:FindFirstChild("RainScript").Rain)
local CurrentCamera = workspace.CurrentCamera

local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:FindFirstChild("Humanoid")

local RoofHitbox = MapFolder.RoofHitbox
EnteredRoof = false

    if CurrentCamera.CFrame.Position.Y > RoofHitbox.Position.Y and EnteredRoof == false then
        EnteredRoof = true
        script:WaitForChild("DropIsAllowed").Value = false
        warn(Player.Name.." Entered The Roof")
    elseif CurrentCamera.CFrame.Position.Y < RoofHitbox.Position.Y and EnteredRoof == true then
        script:WaitForChild("DropIsAllowed").Value = true
        warn(Player.Name.." Left The Roof")

CurrentCamera.CFrame.Position.Y is going to change based on how far up or down the camera is facing. I recommend looking into raycasts.
