Roblox Lighting & Atmosphere
When to Load
Load for Roblox lighting, atmosphere, day/night, or post-processing (Bloom, ColorCorrection, DepthOfField).
Quick Reference
Lighting Service
luau
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
-- Configure tech/style/quality in Studio; these properties are not script-writable.
-- Verify enum values and device behavior against current Creator Hub docs before setting them.Atmosphere
luau
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 = LightingPost-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
luau
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.
- Avoid black Ambient. Technology is deprecated; it and its replacements are Studio-only.
