CG Compositing Series – 2.1 Material AOVs – Diffuse, Specular, Emission

In this video I cover Material AOVs. We talk about different levels of complexity, Simple, Intermediate, and Complex. And the 3 Main Divisions which are Diffuse, Specular, and Emission.

We talk about physically based rendering (PBR) and how the diffuse and specular components are divided, both scientifically in the real world and by the computer on rendering calculations
