Postprocessing effects add that little extra something that can set your game apart. Technically, they are beyond the scope of this book, but we can do a super-fast visit just for fun.

Recall that there are things called scriptable render pipelines. Currently, by default, Unity supports what is called built-in pipelines. Also available are the Universal Render Pipeline (URP) and the High Definition Pipeline (HDP). We are using a built-in pipeline. Eventually, URP will become the default, but that is a tale for another day:
