Hey elisa_christie ,

Just a heads up that a couple of colleagues tried to reproduce this with no success. Do you happen to have a NUMA machine (e.g. a Threadripper, or a Xeon)? I'm trying to think of something that might be different enough from a standard setup to cause the crash.

Best regards!

edit: Never mind, it crashed for me, we'll sort it out. Thank you!

Hey elisa_christie .

The problem should now be resolved in the nightly builds. We'll also look into exposing the debug shading toolbar icon for the V-Ray Frame Buffer.

Hope that helps!

Thanks a lot!
