Rendering 101 pt. 29: PBR Part 1 - The Physics (Patreon)

Physically Based Rendering has been a go-to technique for quite some time now. But what exactly is PBR and why is it important? Manuel sheds some lights on PBR in this tutorial by looking at the physics of light and matter interactions. We learn what physical behaviors of light PBR tries to model and how this helps an artist to save time and effort.
