Understanding and Implementing Lighting in Unity
Explore the fundamental lighting techniques in Unity, including Point, Spot, Directional, and Area lights. Understand how to apply realtime, baked, and mixed lighting modes to optimize both visual quality and performance in your VR projects using Unity's graphics pipeline.
We'll cover the following...
Lighting, in any game project, is extremely important. The significance stems from the fact that it influences a Unity project’s performance, in addition to adding visual appeal. Therefore, as designers or visual artists, we should be aware of where to employ which light. We’ll talk about a handful of Unity’s lights and the options in this lesson.
Note: Although we have different render pipelines, on a fundamental level, all lights operate in the same manner.
Lighting
In Unity, we can add lighting by using light components present in “GameObject > Light.” Currently, there are four types of built-in light components present in Unity, which are as follows:
Now, we’ll discuss each light in detail and learn the use cases where we can add those to make any Unity scene performant and visually pleasing.
Point Light
As the name implies, a Point Light source emits light evenly, spreading out in all directions. As shown in the figure below, a Point Light source releases light beams that dissipate ...
