If you experience this issue after applying the Win10 Fall Creators Update, please reinstall the V-Ray Online License Server (and as @oliver_borg_von_bulo mentioned, make sure you’re using the latest V-Ray version - 3.40.03).
If the problem persists, please contact Chaos Group support.
@Architex , we’ll look into your report, thank you!
@LowEndSoftware , based on the correspondence between you and my colleague, it appears the issue you have experienced is not related to what is being discussed here. You’ve mentioned your system freezing and then crashing when you use up all available system memory by running a large number of SketchUp/Rhino instances with V-Ray loaded. BSODs indicate hardware-related cause (also, please keep in mind, V-Ray is not officially supported on virtual environments).
If you wish to wish to explain the pipeline you want to achieve, please let us know, and we’ll discuss with our dev team possible solutions.
