When rendering in Redshift, in the rop under the AOV section you can select cryptomatte as a custom output. There are four ID Type options you can choose from:
Node Name
Material Name
Object ID
Custom Name ID
Does anybody know how to make option #4 work? It seems like there's a very powerful component to the cryptomatte functionality that nobody is using, unless i'm mistaken. There's no better program than Houdini at making carefully placed and named attributes, but what do you do? I tried making a primitive attribute called "Name" but that did nothing. Is this even implemented in Houdini?
