Lighting Tutorial - How to use Lighting

Viewers on this topic shall acquire a basic understanding of both the Explorer and Properties tab before reading.

This topic is directed to beginners, however can be viewed by those who just learn more about lighting overall.

Lighting properties, post processing effects, and useful plugins will be discussed in this thread.

Why should I use lighting?

Lighting is a vital aspect to your game. It makes your players feel comfortable in a safe-looking environment. Such as showcase games, they are very useful for the type of game you are going to create. Especially for modern builds, realistic sunrays, fog, and atmosphere can set the correct tone.

How does lighting affect the gameplay of players within my game?

Lighting can both positively and negatively affect the gameplay of your players. However, it mostly depends on what style your game is. For example, if you are creating a cartoony game, a cartoony sky would be the best option. Moreover, if you were to create a horror game, dark fog would also be a good option. While it is good to have lighting to sum up the finishing touches of your game, excessive amounts of different settings can negatively affect the performance of players on low-end devices.

Lighting Service

How to Index

The lighting service can be indexed by scripts in the following ways:

game:GetService("Lighting") -- (Recommended Version)

It can also be viewied in the Explorer tab below Players.



This part is probably the most important part that will hugely affect your gameplay. Of course, this is your game, meaning you get to adjust what you would like. Here is a brief explanation of the more important lighting properties that should be altered when possible.


The ambient properly generally changes the hue of your world overall (specifically indoor areas). If you’d like your indoor ambient to be a bit brighter, it is possible that you can use this property and change the color to white.

Other info:
Property of: Lighting
Value type: Color3
Resource: Lighting.Ambient


This is a self explanatory property. This property at default is set to 2. The greater the value, the brighter your world will be.

Other info:
Property of: Lighting
Value type: Float
Resource: Lighting.Brightness


This property will render shadows in more indoor areas, determined by the ambient property. You may set this to false to remove these shadows.

Other info:
Property of: Lighting
Value type: Bool
Resource: Lighting.GlobalShadows


Similar to the Ambient property, this property adjusts the ambient more primarily for outdoor areas, instead of indoor areas.

Other info:
Property of: Lighting
Value type: Color3
Resource: Lighting.OutdoorAmbient


The clock time property runs on a 24 hour clock, determining the position of the sun. For those who use 12 hour clocks, 24 & 0 would be midnight, and 12 would be noon. P.M times would be 12 + hour.

I personally recommend @Maximum_ADHD’s Celestial Body Dragger plugin for easily adjusting the position of the sun/moon.

Other info:
Property of: Lighting
Value type: Float
Resource: Lighting.ClockTime


This property generally shares the same purpose as clock time, but in the value type of a string. This property does not change unless it is changed by a script. Personally, I find no use in this and I’d recommend sticking to ClockTime.

Other info:
Property of: Lighting
Value type: String
Resource: Lighting.TimeOfDay


If you choose to have fog in your game, this property will adjust the hue of the fog similar to the Ambient and OutdoorAmbient functions.

Other info:
Property of: Lighting
Value type: Color3
Resource: Lighting.FogColor


If you’d like fog in your game, this property shall be adjusted. The default value for this property is 100000. The greater this number is the farther the fog is away. If you are looking for mild fog in the background, I recommend setting it to 1000 - 2000. Values lower than that will increase the amount of fog in-game.

Other info:
Property of: Lighting
Value type: Float
Resource: Lighting.FogEnd

I did not cover every single property in that service, mainly due to the fact of less importance. If you would like to learn more about those properties, please use another source to your advantage.

Post Processing Effects

Post processing effects are other effects available to use that are just like properties. The following post processing effects are available to be used:

  • BloomEffect
  • BlurEffect
  • ColorCorrectionEffect
  • DepthOfFieldEffect
  • SunRaysEffect

Post processing effects usually only work while in the Lighting service (therefore it is recommend keeping it there). Post processing effects will only work if the Enabled property in them is set to true. Properties in these effects can be adjusted for the best settings.

How do I add these effects into my game?

You can add these effects into your game by clicking on the circular + when you hover over the Lighting service with your mouse.


Scroll down to Post Processing Effects and click on the one you would like to add.


It should look like this when completed. (It does not have to say “Bloom” like mine, but an effect should go in the service.)




The bloom effect adds additional glow to bright objects (such as the neon material) and the sky. Properties like Intensity, Size, and Threshold can be toggled with. More information can be found here.


The blur effect adds blur to your entire game. In the effect, there is a property called Size that will toggle the strength of the blur. The greater the number, the more blur. Some showcase games have their Blur Size at 1 or 2 to give that perfect feeling. More information can be found here.


The color correction effect is used to adjust multiple color properties at once, such as Contrast, TintColor, Brightness, and Saturation. It is possible for multiple color correction effects to be applied at once. More information can be found here.


The depth of field effect is meant to blur out parts of a game not in direct focus, such as terrain extremely far out. As always, properties can be adjusted within this effect to adjust it to your style. More information can be found here.


My personal favorite, the sunrays effect. This effect adjusts your sun to give it graphic rays, that is highly recommended for realistic games. Properties are very easy to be adjusted on this effect. More information can be found here.

Before/After SunRays



Those are all the individual effects that can be added to make your lighting even better! Multiple effects can be added at once.


Lighting is an extremely important aspect to a game. Tweaking your lighting properties and effects will definitely make a huge impact on the gameplay. I hope this tutorial helped you a bit on what you might have been confused on. If you have any further questions, please reply to this thread. Thank you, happy developing!

Very good tutorial. You should update this to include more about the post-processing affects and also include the new Atmosphere object.

Nice tutorial! The formatting for the Lighting properties is a bit unfortunate though. Here’s some feedback:

  1. The title of the property should be bold (e.g TimeOfDay) and the text that currently is bold shouldn’t be
  2. “Other info:” is just a redundant headline and due to it looking like a head line my eyes kept jumping to it despite it being less important than the property name
