I searched far and wide for a way to render Cryptomattes in Unity but with no success.
The only tool that can do that is the one by Daniel Schmucker:
https://www.schmuckerdaniel.com/unitycryptomatte
Unfortunately, it’s not available anywhere at the moment.
I really hope someone can help me out on this matter.
Like adding a custom Cryptomatte AOV to the Recorder or something like that.
Thank you everyone.
