While AOVs are not managed at the renderer level, the raytracer still offers some options to control how AOVs are computed. For a complete overview of the AOV workflow of the raytracer please refer to the AOVs Workflow section.
Matte Object AOV Mode#
You can set the behavior of matte objects (or holdouts) in AOVs by setting Matte Object AOV Mode.
- When set to Affect Beauty AOVs matte objects are visible in all AOVs except rgba whatever their Matte Alpha value.
- When set to Affect All AOVs, matte objects contribution in AOVs is pre-multiplied by their Matte Alpha attribute value.
You can disable AOV evaluation by disabling Export AOVs. Disabling AOV evaluation can greatly speed up rendering on scenes that have many AOVs.
