Learn how to use the light, light_spot, light_environment entities and the skybox texture to give your maps some light.

In this tutorial I go through the basics of the three most common light entities and the skybox texture.
light - Emits light in all directions, is not very flexible and works best for things like fires. You might think this is the most used light entity but that's actually not the case, the most used light entity is the light_spot.
light_spot - This is a pointed light that emits light in a cone from its origin. This is the most commonly used light entity and is used for almost all kinds of light sources.
light_environment - Used to simulate the sunlight and ambient light in a map. The entity itself does not give off any light, instead it's used to control the light that emits from the skybox texture.
