Add a Custom Skybox
This section will go over changing the default Unity Skybox to an HDRI image.

What is a Skybox?

A β€˜Skybox’ is a flat 2D image that is applied around your Space.
Note: The Skybox will effect the lighting in your scene so it is best to add this early on.
The result simulates the experience of being in a much larger environment. Depending on your skybox texture, it can affect the space with relatively accurate ambient lighting.
