This change will try to add meta data when using a multilayered open exr file output node in the compositor. It adds the current scene meta data and converts existing cryptomatte keys so it follows the naming that is configured in the file output node. This change supports the basic use-case where the compositor is used to output cryptomatte layers with a different naming scheme to support external compositors. In this case the Multilayered OpenEXR files are used and the meta data is read from the render result. Meta data is found when render layer node is connected with the file output node without any other nodes in between. Redirects and empty node groups are allowed. The patch has been verified to work with external compositors. See https://devtalk.blender.org/t/making-sense-of-cryptomatte-usage-in-third-party-programs/16576/17 See patch for example files.
