Hi,
Just that. I've noticed other renderers ship with separate ROPs for creating AOVs that can then be linked to multiple render ROPs and I was wondering how a similar result might be achieved in Arnold.
At a vague guess the solution might be along the lines of writing the LPEs somewhere on disk and then injecting them into the ROPs wherever they were needed. I see some tools to that effect but the syntax isn't entirely clear to me and trialling things is therefore a shot in the dark.
There's always Python, but it strikes me that a more Arnold-centric solution might exist.
