Usage of CryptoObjectPinName?

[increon]

Hello everybody.

Rendering and compositing using the cryptomatte pass became quite essential for me since the respective release of the functionality in both Octane and After Effects.
I would like to ask though what is the workflow of using the CryptoObjectPinName check? It seems no matte is being generated...

Could someone describe the best workflow for it? I couldn't find anything about the PinName in the manual.

Thanks a lot!

Hi,
CryptoMaterialPinName pass works with polygon material selections, so you can easily select a specific material of an object with multiple materials assigned:

Thank you, bepeg4u!

Unfortunately it doesn't work in my case with selections. It only works if I put the object in a separate object layer ID. And then only for the entire object.

Best regards

Yes sorry, both CryptoObjectNode and CryptoObjectPinName are working with Object Layer/Octane Object Tag, while CryptoMaterialPinName works with polygon selections.

Aaah! I think now I got it!
Thanks so much, Beppe. Mille grazie! You helped a lot!

Hi Beppe,

I want to have mattes for each hierarchy of objects.
Each hierarchy consists probably of hundreds of objects with many different materials.
Therefore I can't generate the Cryptomattes based on material (which works, but does not help me).

CryptoInstance, CryptoObjectNode: These create completely new ID's within each render run. This makes it useless if you can not render all frames on one single machine in one single run. Which is the case for my challenge...

CryptoObjectNodeName: I always get one single matte for all objects. The object names are all different. How can I control which objects get in what matte? Can I use this for a whole hierarchy of objects at once?

CryptoObjectPinName: This should work somehow with the Octane Object Tag. But how? What property of the octane object tag controls what belongs together and what not. I always get on single Matte with all objects...
