used to render them is either a box with six textures, or a tessellated sphere.

To implement a Skybox create a skybox material. Then add it to the scene by using the Window->Lighting menu item and specifying your skybox material as the Skybox on the Scene tab.

to a Camera is useful if you want to override the default Skybox. E.g. You might have a split screen game using two Cameras, and want the Second camera to use a different Skybox. To add a Skybox Component to a Camera, click to highlight the Camera and go to Component->Rendering->Skybox.

If you want to create a new Skybox, use this guide.
