CREATE MATTES AOVS – OVERVIEW
Create Mattes AOVs creates RGB (puzzle) mattes for compositing with easy button clicks.
In compositing, you can use the mattes to cut out each shader in your scene, grade the shaders separately or apply effects in your compositing package.
This tool supports Arnold and Redshift. Renderman is only partly supported.
RGB mattes are complex to create and involve building nodes and memorizing many steps.
Create Mattes AOVs creates each matte with a button click. Select an object or shader, and its matte-AOV will be created instantly.
