What is a Sky Box in Unity?

A Sky Box in Unity refers specifically to an image or a series of images that are projected into the background of a scene to simulate the appearance of the sky. This technique creates an immersive environment by surrounding the player or camera with a visual representation of the sky that can include clouds, stars, or other atmospheric effects.

When a Sky Box is applied, it forms the visual backdrop for the entire game scene, helping establish the mood and setting without adding significant overhead in terms of processing power, as it makes use of a flat texture that wraps around the camera.

The correct choice highlights this feature of the Sky Box, emphasizing its role in enhancing the graphical quality of the environment, which can be extremely useful in creating a convincing digital world.
