Cryptomatte Layer Selection

In Nuke I seem to only be able to randomly select one Layer of cryptomatte elements. In nuke I see them in the layer viewer VrayCryptoMatte_AAA_### VrayCryptomatte_BBB_### but when I try to change BBB to AAA it just changes back to the first layer.

Is there a render element naming convention I need to follow carefully or something?

It seems to work fine for me; can you post an OpenEXR file that behaves like that?

Best regards,

Solved it. I had VrayCryptomatte_BBB but VrayCryptoMatte_AAA

Case sensitivity in “matte”. Whoops!

Phew :slight_smile: Thanks for the update!
