The Lighting window (menu: Window > Rendering > Lighting Settings) is the main control point for Unity’s Global Illumination (GI) features. Although GI in Unity gives good results with default settings, the Lighting window’s properties allow you to adjust many aspects of the GI process, to customise your Scene or optimise for quality, speed and storage space as you need. This window also includes settings for ambient light, halos, cookies and fog.
光照窗口(菜单:窗口>渲染>照明设置)是Unity全局照明(GI)功能的主要控制界面。虽然Unity中的GI在默认设置下提供了很好的效果，但是光照窗口的属性允许你调整GI处理的许多方面，来定制你的场景，或者根据你的需要优化质量、速度和存储空间。该窗口还包括环境光、光晕、剪影（cookie）和雾的设置。

Overview 概述

The controls of the Lighting window are divided among three tabs:

• The Scene tab settings apply to the overall Scene rather than individual GameObjects. These settings control lighting effects and also optimisation options. 场景选项卡设置应用于整个场景，而不是单个游戏对象。这些设置控制灯光效果和优化选项。
• The Global maps tab shows all of the lightmap Asset files generated by the GI lighting process. Global maps选项卡显示GI照明过程生成的所有lightmap资产文件。
• The Object maps tab shows previews of GI lightmap textures (including shadow masks) for the currently selected GameObject. 对象地图选项卡显示当前选中的游戏对象的GI lightmap纹理(包括阴影遮罩)预览。

The window also has an Auto Generate checkbox below the displayed content. If you tick this checkbox, Unity updates lightmap data as you edit the Scene. Note that the update usually takes a few seconds rather than happening instantaneously. If you leave the Auto Generate box unticked, the Generate Lighting button to the right of the checkbox becomes active; use this button to trigger lightmap updates when you need them. Use the Generate Lighting button if you want to clear the baked data from the Scene without clearing the GI Cache.
该窗口还在显示内容下方有一个自动生成复选框。如果你勾选这个复选框，Unity会在你编辑场景时自动更新光照图数据。注意，更新通常需要几秒钟，而不是立即发生。如果不勾选“自动生成”框，复选框右侧的“生成照明”按钮将变为活动状态;当你需要的时候，使用这个按钮来触发光照图更新。如果您想在不清除GI缓存的情况下清除场景中烤好的数据，请使用Generate Lighting按钮。

Scene tab

The Scene tab contains settings that apply to the overall Scene, rather than individual GameObjects. The Scene tab contains several sections:

• Environment 环境
• Realtime Lighting 实时光照
• Mixed Lighting 混合光照
• Lightmapping Settings 光照图设置
• Other Settings 其他设置
• Debug Settings 调试设置

Environment 环境

The Environmental Lighting section contains settings for the skybox, diffuse lighting and reflections.
环境光照部分包含天空盒、漫射光照和反射的设置。

Property	Function
Skybox Material	A skybox is a Material that appears behind everything else in the Scene to simulate the sky or other distant background. Use this property to choose the skybox Material you want to use for the Scene. The default value is the Material Default-Skybox in the Standard Assets.
