Adding global illumination and other settings

In this section, we are going to give our shop scene a background by adding art assets from the level3 scene and adding a red emission material.

Unity is currently working on a new global illumination lighting package, which means this version we are using will be eventually phased out. The good news is that it will be supported during 2020 LTS.

We will activate the scene's real-time global illumination, which is where the red emission material will glow on the surface of the corridor. We will also be adding extra lights to our shop display and the player ship to make it stand out more. Finally, we will add some black fog to create some darkness creeping around the glowing lights.

The following screenshots show a comparison between the shop scene before and after we complete this section:
