Bizzare Crash Logs

[avery_brown]

One of our render nodes is having persistent errors running VRay for 3ds Max. It seemed like the CPU was possibly to blame, so I wanted to push it and see if anything bad happened. I tried to run VRay Benchmark on and it failed to start. However, when I looked at the log, the error description is that, "the impossible has happened."

I was wondering if anyone else has encountered the impossible and if there is a clearer meaning to this log entry. I also wonder if the line, FatalError "Scenes have been changed!", has anything to do with the error which was crashing VRay for 3ds Max which also mentioned scenes. Possibly to do with some sort of issue with Embree?

VRay for 3ds Max error:

error: Building Embree Voxel Tree failed: [EmbreeTree<0,1,class VUtils::StaticTreeDelegateParam,struct VUtils::SimpleStaticTriangle,struct VUtils::SDTreeBunchDelegetorFace>::build] 1: Creating new scene failed

Hello avery_brown, and thanks for submitting your issue!

The Scenes have been changed! error in most of the cases means, that either there isn't enough space on the disk, or the scenes literally have been changed, while the application was still running.
You might try closing the application, removing the directory %TEMP%/V-Ray Benchmark, and running the application again, although if there really isn't enough space on the disk, that won't help.

I'll be happy to further assist in resolving your issue!

Best regards,
Daniel

Thanks daniel.taskoff! Deleting the folder worked, but only once. I wonder if there is a problem with the disk? Anyways, thanks again for the response!

[daniel.taskoff]

You're welcome!

Just to verify - how much free space do you have on the disk, where %TEMP% is located?

And could you please list the contents of the %TEMP%/V-Ray Benchmark directory after running, and closing the application?

[avery_brown]

There are 342 GB free out of a total of 446 GB. The remaining contents of the %TEMP%/V-Ray Benchmark directory are two folders, one for "logs" and another called "%SystemDrive%". For some reason Benchmark is running fine today, so the leftovers in the folder don't seem to be the same as when it was crashing yesterday.

[daniel.taskoff]

Seems like for some reason the automatic uninstaller failed to clean the installation directory, since only the two folders you mentioned above should persist after closing the application.

Anyway, I'm glad that you can now run the benchmark! If any other troubles occur with the application, please let us know.

Thanks Daniel!
