ExposureCompensation Script not working?

Help and Feedback Scripting Support
#1

so basically, im trying to make an exposurecompensation script, but it doesn’t work. it works once when you climb up a truss with something above it as a ceiling. i want it to lower to 0 outside, raise to 1 inside. tried on devforum discord and sh discord and got no luck. it doesnt lower outside, nor raise inside.

local player = game.Players.LocalPlayer
repeat wait() until player.Character
local character = player.Character
local head = player.Character:WaitForChild("Head")

function raiseExposure()
    local exposure = math.clamp(0,0,1)
    for i = 1,10 do
        wait()
        exposure = exposure +0.1
        game.Lighting.ExposureCompensation = exposure
    end
end

function lowerExposure()
    local exposure = math.clamp(0,0,1)
    for i = 1,10 do
        wait()
            
        exposure = exposure -0.1
        game.Lighting.ExposureCompensation = exposure
    end
end

function castRay()
    local originVector3 = head.Position
    local castDirection = head.CFrame.UpVector
    
    local castParameters = RaycastParams.new()
    castParameters.FilterDescendantsInstances = {head.Parent}
    castParameters.FilterType = Enum.RaycastFilterType.Blacklist
    local castResult = workspace:Raycast(originVector3, castDirection, castParameters)
    
    if castResult then
        local hitPart = castResult.Instance
        if hitPart.Transparency <=.8 then
        raiseExposure()
    elseif not castResult and not hitPart then
            lowerExposure()
            end
        end
end

while wait(.1) do
    castRay()
end
