Thanks Edwin, thought it might be hiding somewhere.
Few last bits if you don’t mind 
Are there any options to specify the render limits in SMTDSettings so I can add specific limits to our cloud jobs?
I thought it might be:
SMTDSettings.LimitGroups = “maxcloud, deadline”
but that didn’t pick any up.
Also, where do I specify auxiliary files to upload with the job? I got an error message saying Xrefs needed adding to the job. At the moment I’m just merging everything, but if I want to get it farm friendly, I would prefer everything to be kept separate.
Thanks again!
