@matt_newberg Any idea?? Update: After playing around on V-ray, this seems a random behavior. Can be ignored for now…

I removed the (SOLVED) from the thread title, as this behavior is still around. Would love to see this get resolved.

I believe this issue was also resolved with the solution in this post: [image] (Solved) V-ray freezes for NO REASON @matt_newberg Thanks matt, I downloaded it after seeing Dave post. I did a quick test yesterday. The Materials I used updated in real time. I can feel the difference. …

Imported materials don’t update.

@KevJin Do you have steps required to duplicate the issue?

@matt_newberg This can be easily produced by importing .vsr? (Vray material format.) Will update this thread when I use Rhino and V-ray next time…

I am still getting window freezes with the latest update. Only with the material editor thus far, and not the Options yet. Most seem to occur randomly, but one happened when a render completed and I was a couple levels deep in editing a material. Eventually, switching between windows I was able t…

I have the solution. Search for “vrayforrhino.ini” in: C:\ProgramData\ASGVIS (program data is a hidden folder) open It with wordpad, scroll down until you find [Licensing] gui_timeout_minutes=5 Change the value from “5” to “-1” Problem solved…

Wow, I hope that is it, will try that. Thank you. @matt_newberg Are you aware of this setting being problematic?

@gregb Yes disabling the gui_timeout_minutes can resolve freeze issues for some users. People that share a network dongle will still need that setting turned on.

Thanks for the reply. I hope for other users’ sake a fix is being worked on, or at least defaulting to the disabled setting for non-network dongles, because that is certainly a serious bug. I haven’t had a freeze again yet, will update if I do.
