How to Use Lights and Cookies in Unity to Beautify the Scene (Part 2)

Posted February 10, 2020 by Joudet Ahsan in Unity

This tech-recipe is a continuation of the previous article How to Use Lights and Cookies in Unity to Beautify the Scene (Part 1). This part will be a complete guide of lights and cookies in unity.

Lights are an important part of a scene. If you want to simulate a haunted scene, you can display a cross cookie reflected on the walls. Or you can put point lights on graves. Area lights can be used to light up disco walls. Even house lighting can be simulated.

In theatre and film, lighting effects have long been used to create an impression of objects that don’t really exist in the set. A prison scene often shows the light coming through the barred window, even though the window and indeed the wall are not really part of the set.
