I just updated from V-Ray 5 to V-Ray 6 and immediately found a snag.
Upon opening old scenes, I get a " VrayPluginNode: unsupported plugin(s) found" pop up. A quick search pointed out it’s due to some now-unsupported material nodes, and I “sanitised” all materials and material libraries from the affected nodes.
However, the scenes I render use XRefs extensively, and 3ds Max and V-Ray are stubborn, and one of the two insists trying to load the unsupported nodes, even if the XRef material no longer uses them.
The only solution I’ve found so far would be to delete the affected XRefs and relink them, but I’d have to do that on 479 files (not joking) and resubmit them to Deadline.
I’ve tried to modify the submission parameters of the jobs, setting to “true” the “Render In Silent Mode” option, but the pop-up still appears and the render is marked as failed.
Very quick update: after some extensive help from the support desk (thanks again Zain ), I was able to overcome to pop-up through a combination of updating Deadline and 3ds Max’s plug-in to the latest version.
