RT crashing, but not sure why

Here’s a screengrab.

Any ideas? There are quite a few ies light sources, and some pendant lights that have vray2sided materials applied.

Can you get me the .dmp file from the error message? Also, is it a repeatable bug? If you look at the GPU memory usage, what is it?

Best regards,

switched to CPU and rendered, then back to GPU and now it seems fine. A temporary glitch.

(does GPU support vray2sided materials?)

Working on it.
