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 Time Stamps: 00:00 - Intro - Material AOVs 00:58 - Different Complexity Levels 03:26 - Diffuse, Specular, Emission Categories 05:14 - Adjectives of Diffuse, Spec, Emission 06:40 - Diffuse Reference Photos 07:44 - Specular Reference Photos 09:23 - Diffuse + Spec Component Reference 12:16 - Emission Reference Photos 13:09 - Intro Slide 13:38 - EMISSION 15:22 - SPECULAR Intro 16:03 - Law of Reflection 16:32 - Smooth Surface Reflections 17:14 - Planar Mirror and Virtual Image 19:13 - Rough Surface Reflecitons 21:40 - Smooth vs Rough Materials 23:06 - Wet Surfaces 23:55 - Microscopic surface details 25:03 - Metallic vs Dielectric Intro 25:28 - Dielectrics 25:14 - Metallics 27:26 - Metallic vs Dielectric Materials 30:12 - Chrome Sphere and Diffuse Ball 31:08 - DIFFUSE 34:42 - Sub Surface Scattering (SSS) 36:55 - Albedo Maps 38:06 - Metalness and Roughness Maps 39:26 - Materials with Diffuse + Spec Component 39:53 - Iridescence 40:56 - Nuke Simple Rebuild 42:20 - Recap 43:55 - Outro Please visit the blog post for the full write up, sources, references, work files, and render downloads accompanying the video. https://compositingmentor.com/2023/01/27/cg-compositing-series-2-1-material-aovs-diffuse-specular-emission Or Head to my Compositing Blog for more posts and videos: https://compositingmentor.com
