Roblox Lighting & Atmosphere

When to Load

Load for Roblox lighting, atmosphere, day/night, or post-processing (Bloom, ColorCorrection, DepthOfField).

Quick Reference

Lighting Service

Lighting.ClockTime = 14            -- 0-24 numeric
Lighting.Brightness = 2            -- 0-10, default 2
Lighting.Ambient = Color3.fromRGB(70, 70, 70)        -- shadow fill
Lighting.OutdoorAmbient = Color3.fromRGB(128, 128, 128)
Lighting.GlobalShadows = true
Lighting.ShadowSoftness = 0.2      -- 0=sharp, 1=soft
-- Current Studio uses LightingStyle and PrioritizeLightingQuality instead of Technology.
-- Verify enum values and device behavior against current Creator Hub docs before setting them.

Atmosphere

local atmo = Instance.new("Atmosphere")
atmo.Density = 0.3    -- 0=clear, 1=opaque (keep <0.5)
atmo.Offset = 0.25    -- 0=ground, 1=sky
atmo.Color = Color3.fromRGB(199, 199, 199)   -- near fog
atmo.Decay = Color3.fromRGB(92, 92, 92)      -- far/horizon
atmo.Glare = 0        -- 0-10
atmo.Haze = 0         -- 0-10
atmo.Parent = Lighting

Post-Processing (all parented to Lighting)

Effect	Key Properties
`BloomEffect`	Intensity (0-1), Size (px), Threshold (>0.7 recommended)
`ColorCorrectionEffect`	Brightness, Contrast, Saturation (-1 to 1), TintColor
`DepthOfFieldEffect`	FarIntensity, FocusDistance, InFocusRadius, NearIntensity
`SunRaysEffect`	Intensity (0-1), Spread (0-1)

Day/Night Cycle

local CYCLE_SPEED = 1  -- minutes per full day
task.spawn(function()
    while true do
        Lighting.ClockTime += (task.wait() / 60) * (24 / CYCLE_SPEED)
        if Lighting.ClockTime >= 24 then Lighting.ClockTime -= 24 end
    end
end)

Local Lights

Light	Use	Key Props
`PointLight`	Lamps, torches	Range, Brightness, Color
`SpotLight`	Flashlights	Range, Angle, Face
`SurfaceLight`	Screens, panels	Range, Angle, Face

Perf: Limit shadow-casting lights to 4-6 visible. Use Shadows=false on most. Neon material = cheap glow.

MCP: Inspect, change minimally, capture, check performance.

Common Pitfalls

Brightness >3 washes out. Density >0.5 = soup. Max 2-3 post effects.
Ambient should not be black. Use LightingStyle/PrioritizeLightingQuality; never set deprecated Technology.
