Vray crashing Rhino 6 and Rhino 7...I think?

[ds73]

I am experiencing crashes in both Rhino 6 and 7 with the latest build of Vray. I am not sure exactly what the pattern is, but generally speaking the crashes happen while I'm running an interactive RTX render (2xRTX2080Ti) and am making adjustments to materials or lighting in the Asset Manager. For instance, last crash today happened while I was modifying the brightness of a reflection map of one of the stock concrete textures. I've had similar issues with crashes while adjusting bump map levels, coat color and gloss level, etc.
How best to de-bug this issue? Rhino does not produce a crash log in these events FWIW.

Hi ds73,

Thank you for reporting this.
Crashes like the one described are not easy to reproduce and debug.
They might be happening in a very specific scene configuration or might be random.
Most often than not though they are caused by a some specific shader in the scene.
Can you please save out the material you mentioned as a .vrmat and share it?
It might help us get to the root cause for this.

Regards,
Konstantin
