Full-Screen Effects with Post-Processing

So far, we have created different objects to alter the visuals of our scene, such as meshes, particles, and lights. We can tweak the settings of those objects here and there to improve our scene quality, but you will always feel that something is missing when comparing it with modern game scenes, and that is post-processing effects. In this chapter, you will learn how to apply effects to the final rendered frame, which will alter the look of the overall scene.
