V-Ray Progress Window returns to 0%

[Mr.Bee]

Hello, I hope somebody is able to offer assistance to enable me to rectify a problem that has recently surfaced with the V-Ray progress window.
On most occasions now when the render process reaches about 90% complete, inexplicably the progress window returns to 0% and begins the render process over. Its time I can ill afford to waste and hopefully someone can shed some light on what is the issue.

Thank you.

Hello,

The problem has been identified to occur when the SketchUp project is saved or autosaved during progressive rendering. A fix will be included in the upcoming v4.10.02 minor update.
In the meantime, the only workarounds I can advise are to either increase the SketchUp auto-save timer (Window > Preferneces > General) or turn off the Progressive sampling mode toggle in the V-Ray Asset Editor's Render settings.

Kind regards,
Peter

Thank you Peter. I very much appreciate your reply.
I’ll adjust the auto save backup to allow for render time and hopefully that will sort it out. Now that you’ve brought it to my attention, it makes perfect sense. Many thanks.
