Hey,
I need to render with objectsID AOV, with Arnold, and I'm failing miserably :/
In the AOVs liste, there's an ID aov, but can't make it work.
So I looked into Cryptomatte since I'm using ALshaders. I can't find info about how to use it, just a tutorial for maya on anderslanglands.com, where it seems simple (just enable crypto_object and crypto_material). But there's no such things in Houdini :/
All I can see about cryptomatte is in the shader nodes, there's an AOV tab with confusing things...
Can you help ?
