I'm getting back to this thread a day or two later.
Thanks, Ahmet, that worked. It honestly hadn't occurred to me to try each matte option to see if they behaved differently between renders.
I know you are juggling a lot of balls, but perhaps this very important attribute of the CryptoMaterialNodeName pass can be indicated more explicitly in the interface, as well as included in the Octane docs. There's already a section in the docs for Cryptomatte called IMPORTANT NOTES, and this seems like a good fact to include there.
