# LightingSettings > An object containing settings for precomputing lighting data, that Unity can serialize as a Lighting Settings Asset. ## Definition * **Type:** Class * **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md) * **Assembly:** UnityEngine.CoreModule * **Inherits from:** [Object](/engine/6000.7/script-reference/unityengine/object.md) ```csharp public sealed class LightingSettings : Object ``` ## Remarks When the Unity Editor precomputes lighting data for a Scene that uses the Baked Global Illumination system or the Enlighten Realtime Global Illumination system, it uses settings from a `LightingSettings` object. The same `LightingSettings` object can be assigned to more than one Scene, which makes it possible to share settings across multiple Scenes. The following example shows how to create a `LightingSettings` object and assign it to the active Scene using the [Lightmapping.lightingSettings](/engine/6000.7/script-reference/unityeditor/lightmapping/lightingsettings.md) API: ```csharp using UnityEngine; using UnityEditor; public class CreateLightingSettingsExample { [MenuItem("Example/Create Lighting Settings")] static void CreateExampleLightingSettings() { // Create an instance of LightingSettings LightingSettings lightingSettings = new LightingSettings(); // Configure the LightingSettings object lightingSettings.albedoBoost = 8.0f; // Assign the LightingSettings object to the active Scene Lightmapping.lightingSettings = lightingSettings; } } ``` The following example shows how to create a `LightingSettings` object, and save it to disk as a Lighting Settings Asset using the [AssetDatabase.CreateAsset](/engine/6000.7/script-reference/unityeditor/assetdatabase/createasset.md) API. ```csharp using UnityEngine; using UnityEditor; public class CreateLightingSettingsExample { [MenuItem("Example/Create Lighting Settings")] static void SaveExampleLightingSettingsToDisk() { // Create an instance of LightingSettings LightingSettings lightingSettings = new LightingSettings(); // Configure the LightingSettings object lightingSettings.albedoBoost = 8.0f; // Save it to your Project, using the .lighting extension AssetDatabase.CreateAsset(lightingSettings, "Assets/ExampleLightingSettings.lighting"); } } ``` Additional Resources: [Lighting Settings Asset](/engine/6000.7/manual/lighting-overview/lighting-reference/class-lighting-settings.md). ## Properties | Property | Description | | -------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [albedoBoost](/engine/6000.7/script-reference/unityengine/lightingsettings/albedoboost.md) | The intensity of surface albedo throughout the Scene when considered in lighting calculations.
