Issues with the new release of Vray

Is anyone else having issues with the new release of VRay. I have had materials simply disappear between modelling sessions. Yesterday I watched a lot disappear right before my eyes, just as if someone was deleting them.

Is anyone else seeing anything similar?

Nope, for me V-Ray 4.1 is super-comfy to use. Can’t remember any troubles whatsoever so far.

Works quite stable here too. Only different little issues, but ok for production use.

Paul are you sure that you have the new V-ray version? I downgraded by accident couple weeks ago und had similar issue with materials.

Hummus, I think so, but I will check!
