CG Compositing Series – 2.4 Material AOVs – Albedo & RAW Lighting

In this video, we continue breaking down the Material AOVs into smaller components. We learn about the Albedo (texture) pass and RAW Lighting.

We explore:

* Albedo and Raw Lighting: What they are, identifying them, and learning how they help shape the diffuse and specular layers.
* Separate, Change, Recombine: A powerful workflow of division and multiplication to help build up or break apart passes.
* Division problems: Solve issues you might encounter when dividing in nuke.
* Recombination strategies: I guide you through various approaches to recombining your CG. Incorporate all components, from simple to complex.
* Realistic Template: I introduce a realistic CG AOV template of how I might setup a CG rebuild in a production setting, for maximum clarity and flexibility.
