Cryptomatte for Arnold GPU

Good day,

 

We're currently evaluating a switch to Arnold GPU from CPU for upcoming productions.

However, we are evaluating Arnold VS some other engines alongside this.

 

There is a good chance it may boil down to 1-2 currently missing features in Arnold GPU that could be make or break for us.

  1. Cryptomatte AOV.
  2. Shadowmatte

It's been a while since new posts were made about these features, so I'm following up.

Can you reveal any ETA for the inclusion of at least Cryptomatte in Arnold GPU?

 

all the best,

amwilkins

No, I'm sorry, but I cannot give out ETAs or promises for new features. Cryptomatte for Arnold GPU is certainly something we want and plan to do.

Okay, thanks for the reply Stephen. Appreciated.

I won't hold out for it in the next 1-2 years then.

 

I'm sad this is the case however, been requests since at least 2019 on this forum.
Is there any reason why such an important feature like Cryptomatte has been so de-prioritized?

Redshift, Karma, hell... even Unreal all has this feature.

 

all the best,

If it happens I would expect sooner that 2 years.
It's not deprioritized, it's just not as simple as all that in the Optix rendering framework, as I understand it. Along the same lines, there's no public Arnold GPU API for custom shaders or other plugins (and Cryptomatte is a bunch of custom plugins).
