Short description of error
Cryptomatte - File Output node is messing up the multilayer exr, so blender cryptomattes are not working in the compositing app Blackmagic Fusion 9.
Exact steps for others to reproduce the error
Open the attached blend-file.
Hit render animation.
Two files are generated within the tmp folder.
One from the compositor file output node (Cubes_Cryptomatte_test_FileOutput_0001.exr)
and one from the core output in the output properties (Cryptomatte_Cubes_test_0001.exr).
As you can see on the filesize of these multilayer exrs, they are not the same, but should?!
If you try to use the cryptomatte channels in these files in the free compositing app Blackmagic Fusion 9 only the cryptomattes frome the one, which wasn´t save though the file output node, works correct.
Is the file output node in the blender compositor changing something in the multilayer exr?
In Fusion Cryptomatte_Cubes_test_0001.exr - The Channel IDs are recognized by Fusion.
In Fusion Cryptomatte_Cubes_test_FileOutput_0001.exr - The Channel IDs are not recognized by Fusion.
The error message whithin Fusion.
