Thanks for the thoughts Rich, but I don't think its a solution.
Sleeping is one of the first things I tried, but it blocks Nuke so the
functions don't actually happen. Nuke races to try and do them all at once
after the sleep and just drops most of them.
As for using a conditional, i'm not sure how I would set that up, but i'm
fairly certain it isn't an option because these keys need to be set, so that
Ocula can do its thing BEFORE rendering begins.
Unless I misunderstood you?
