Use for Roblox lighting, atmosphere, day/night, or post-processing effects.

Instructions onlySoftware Development

AI-generated overview

Reference for configuring Roblox lighting, atmosphere, day/night cycles and post-processing effects.

What it does: This skill provides a quick reference for Roblox environment settings: the Lighting service properties, Atmosphere instances, post-processing effects such as Bloom, ColorCorrection, DepthOfField and SunRays, day/night cycle code, and local light types. It also lists common pitfalls and performance notes, and points to a fuller reference file with mood presets, zone tweens and complete examples. It is instructions only and ships no scripts.
When to use it: Use it when working on Roblox lighting, atmosphere, day/night cycles or post-processing effects in a project. It is meant as a lookup while configuring or scripting those environment elements.
Requirements: No scripts are included; it is instructions only. It references Roblox Creator Hub documentation and a bundled reference file, and assumes a Roblox Studio or Luau context.

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

luau

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

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

Local Lights

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.
