Cryptomatte Solaris Docs

I can’t seem to find clear documentation regarding VRay for Solaris Cryptomatte implementation anywhere. I must have found it at some point, because I’ve got some nodes with esoteric syntax that works - but now can’t seem to find any reference to it online. If this does indeed exist, it’s not in any of the obvious places within the documentation
Not here https://docs.chaos.com/display/VRAYH…ay+Cryptomatte
Not here https://docs.chaos.com/display/VRAYH…nts+in+Solaris

I would expect the information needed to exist in both of these places… and by all means correct me if I’m wrong, I just can’t seem to find it anywhere.

Additionally, I also can’t find Render Var info clearly documented as it pertains to using sampler:xxxxxxx raw inputs. Having this filled out would also go a long way, I shouldn’t have to dig through forums for either of these things.

Is this still the best way:

source name:
cryptomatte:kind:component
(for components)
__name
(for name)
__materialname
(for material name)

and I presume I still have to update the params ont he vray tab also (and ‘enable cryptomatte’)

Hey @bender83 ,

The V-Ray Standard Vars LOP is an HDA - you could dive inside and check out the example setups for the Cryptomatte and Sampler AOVs.

Best regards!
