Custom render passes are added in the Shader AOVs panel in the view layer settings, with a name and data type. In shader nodes, an AOV Output node is then used to output either a value or color to the pass. Arbitrary names can be used for these passes, as long as they don't conflict with built-in passes that are enabled. The AOV Output node can be used in both material and world shader nodes. Implemented by Lukas, with tweaks by Brecht. Differential Revision: https://developer.blender.org/D4837
