# Atmosphere Module

## Overview

The Atmosphere Module provides dynamic control over the skydome, fogdome, clouddome, and lighting settings. This module allows you to use gradients and curves (setup in an [Atmosphere Profile](../profiles/atmosphere-profile)) to detail the way that your scene's colors look in your game.

✅  Has equivalent COZY Biome Module

❌ Overridden by the BLOCKS Module

## Key Features

### Sky Dome Controls

* Control sky colors
* Control stars, rainbow, galaxy, and light scattering FX
* Control rainbow size and placement (rainbow brightness is controlled by the [Material Manager Module](interactions-module)
* Control sun and moon halos

### Fog Dome Controls

* Control the fog color
* Control the fog density
* Handle variation with the fog
* Change the way that light illuminates the fog

### Cloud Dome Controls

* Manage properties for the individual [cloud styles](../the-weather-sphere/the-cloud-dome)
* Provides controls for the default [Cloud FX](../profiles/fx-profiles/cloud-fx) if the weather module is not active on the Weather Sphere

## Usage Examples

### Change the color of the sky to orange at sunset

Change the color of the Sky Zenith gradient, Sky Horizon, Fog Colors, and Light Flare to orange around 75% of the way through the gradient. See the documentation on Meridiem Time for an explanation on why this works!

### Decrease the brightness of the ambient light at night

Set your ambient light multiplier property to interpolate

Then lower the magnitude of the curve between 0.75 to 1 and 0 to 0.25
