The Environment lighting settings offer the ability to specify contributors to environmental illumination including a Skybox and Fog. A Skybox is a panoramic texture representing the sky that is drawn behind all objects in a scene as if at a far distance. We used the Wispy Skyboxes, for example, in previous chapters, and Skyboxes are discussed in more detail in Chapter 11, Using All 360 Degrees. More than rendering how the sky looks, with the Environment Lighting settings opened (using Window | Rendering | Lighting | Environment), you can specify if and how much the Skybox texture contributes to the Global Illumination and set its intensity level, as shown in the following screenshot:
For more details on using these and other settings in this window, consider the following pages from the Unity Manual:
