Jeroen Bakker continues his compositor improvement spree, now adding the ability to read Cryptomatte metadata from multilayer OpenEXR files. Previously, Cryptomatte metadata was only generated at render time.

This also goes in the direction of planned changes to the Cryptomatte node, which will use metadata for name matching and color picking. Jeroen demonstrates the ability to read the metadata in the video below:
