Default template Lighting and Skybox (where doest the light comes from?)

After creating the default first person template I’m trying to understand what is illuminating the entire scene.

I can see 1 directional light but even if I remove it the scene is still illuminated,
I presume that is the skybox that is doing all the lighting but I don’t understand how it works.

Let’s say that I want a game that plays at night, what are the required steps to achieve that? Any examples available?

thanks :slight_smile:

thanks! at step 2 I learned what I needed

thank you
