* This adds a **Light** object that can be added on the scene, with a customizable color and radius.
* Add the **Light Obstacle** behavior to the object that must acts as obstacle (walls, etc...) to the lights.
* You can customize the ambient color of the rest of the scene from almost white (useful to show light shadows) to entirely black (useful for horror/exploration games) or any color.
* Use effects on the "Lighting" layer like "Kawase Blur" to achieve soft shadows.
