VRayCryptomatte issue

V-Ray V-Ray for 3ds Max Issues
1

So I’ve got the Psyop Cryptomatte setup in Nuke 8 and it’s working with their sample images - but I can’t get it to work with my vray renders. [GitHub - Psyop/Cryptomatte: Cryptomatte Nuke plugin, Fusion plugin, sample images, and specification · GitHub]

I’m running Vray 3.60.03, outputting V-ray RAW multichannel exr with the VRayCryptomatte element. I see in Nuke that there are 4 layers, VRayCryptomatte, VRayCryptomatte00, VRayCryptomatte01, & VRayCryptomatte02

Does anything need to be shuffled around or renamed to work correctly with the Psyop plugin? The Troubleshoot button is telling me that ‘No Cryptomattes found in input’

Am I missing a step?

Weird - must have just been up too late trying to get it working. Today after a windows update and machine reboot, it’s working!
It might have also been that I was still using a multi-channel exr saved from the vray frame buffer, and not the raw multi channel exr I had rendered later…

Fun!
