Hi @comlys, I am having a same issue on 5.5.4
There are layers called objectID1, 2..
but Nuke does not recognise them as cryptomatte.
If I use normal MRQ setting “object ID” it works.
If I put viewmetadata node in nuke to the rendered exr from rendergraph, I see no information regarding cryptomatte is outputted. Whereas old MRQ render has tons of information such as actor name, material name etc…
(I loved your Render Graph youtube tutorial by the way!)
