cryptomatte doesnt work from fileout put node in blender compositor, in fusion

but works in after effect, so I think it can be done in fusion too.

EvanAW commented 3 years ago

This isn't an issue with Cryptomatte, but instead it was a long standing issue with Blender's compositor not passing any metadata to the file output node.

This was fixed 3 days ago (Jan 12, 2021) in the 2.92 Beta and 2.93 Alpha builds available at https://builder.blender.org/download/.

Just saw your reply now.

Testing with Blender 2.93.0 Alpha hash: 886486615b35, DaVinci Resolve v17.0.0b.0013, and Cryptomatte 1.2.8, I have no issue using multiple types of ID's in the same Multilayer EXR file.

Looking into this further, it appears that you are having the same issue as others have reported in https://github.com/Psyop/Cryptomatte/issues/100, that PR https://github.com/Psyop/Cryptomatte/pull/120 is meant to fix.

It is an issue with hash to float conversion in Cryptomatte's Fusion plugin sometimes creating NaN values.

Fixed thanks to collaboration with user who created PR #120. Will be shipping in next big release.
