Dear, if I use team render and there are xrefs in my file then there are missing pieces of image in my visual ... or sometimes the render just does not render at al. The team render starts and then stops after a few seconds ... I'm only just starting using Xrefs. The Xrefs are all grouped together in a folder on our server. I find very little information about this problem ...
When i render without team render there is no problem, when i delete the xrefs there's no problem also.
My guess on this would be the file size. Team render drops out if the file is too large to send over a network.
In the preference settings there is an option to change that drop off point, but you'll have to change that on all the machines in your team.
