Lighting the scene

Our goal is to make a solar system, not just a spinning globe. That means we need to illuminate the planet from the side as if it were receiving sunlight. We will do this by replacing the default scene lighting with point light.

First, remove the default lighting:

1. In Hierarchy, delete Directional Light.
2. Next, go to the Lighting panel. If it's not enabled, go to Window | Lighting | Settings and drag its tab next to Inspector.

 

3. In Lighting , on its Scene tab in the Environmental Lighting section, set Source to Color and Ambient Color to black (000).
4. Also, in the Environmental Reflections group, set Intensity Multiplier to 0.

This looks pretty dark.

Adding sunlight

Unity provides a variety of different types of light sources for your scenes. For the sunlight, we are going to use point light since it radiates in all directions:

1. In Hierarchy, go to Create | Light | Point Light and name it Sunlight (you may need to go and click on the Inspector tab to expose that panel now).
2. Move it...
