Skybox
The Skybox might seem a strange place to begin an analysis of 2D, but it
demonstrates an important feature set for cameras, specifically layering. The Skybox
is essentially a cube-based background that's attached to a camera to show clouds,
skies, and other distant details that should always act as the backdrop to a scene,
but it never represents anything that the player can move close to. It is always
distant, as shown here:

The main problem with the default Skyboxes native to Unity is that they remain
static and motionless by default. Most developers, however, want their skies and
clouds to gently rotate, even when the camera is standing motionless, to portray the
procession of a day or of time passing. Now, let's create an improved Skybox prefab
using the Unity Skybox assets, two layered cameras, and a C# script file.
The inal project for a rotating Skybox can be found in the topic's
companion files.
For the sample project created here, let's import the
Character Controllers
package
for a first-person controller asset, the
Terrain Assets
package for terrain textures
that we can paint onto a sample terrain, and the
Skyboxes
package for the Skybox
textures, as shown in the following screenshot.
