Summary

In this rich chapter, we have learned a lot of things about lighting in Unreal Engine 5. We started by understanding what Lumen is and how it works. We learned how to use all the different light assets that the Engine provides, and we now understand the difference between static and movable lights. We discovered how Ray Traced Shadows can improve shadows’ quality; we learned that Lumen allows us to illuminate scenes with emissive objects, and we understand how to create a Light Function that makes our light asset flicker. Finally, we illuminated an environment from scratch.

We are coming to the end of the first part of this book. In the next chapter, we will overview the newest Unreal Engine 5 features before starting to learn all the techniques needed to create an environment from scratch.
