Why don't shadow mattes work with Arnold GPU?

[moflojoe]

Hey,

When will Arnold GPU have Shadow Mattes working? It's a fundamental feature to rendering and it has been years...

The website states:

shadow_matte

Yes

This initial version has a number of limitations currently: including no support for indirect lighting, no AOV generation, and possibly incorrect self-reflections in shadow-matte objects.

Whenever I use it, it always shows a normal alpha instead of the shadow pass.
It works perfectly fine with CPU but not with GPU... 😞

Any information would be greatly appreciated as we've had to put the project on hold.

It's on our roadmap, but I don't have an ETA.

Thank you for the response but that's a terrible answer...

Will Arnold's GPU features ever be working?

[Stephen.Blair]

Yes. I can't pre-announce features or tell you exactly when things will be implemented and released.
