VrayRT fails with CUDA

[troyhome]

With a fresh file, VrayRT interactive render works like a charm. The minute i try it with a linked Revit file it fails or crashes. I tried reinstalling Max. I installed an older NVIDIA driver. It just gets to 90% in the Vray messages window and then says error: [VrayRTMax: render ThreadProc] Exception occurred in rendering thread.
This is with Revit's default scene.
I'm running 3ds Max 2017 in Windows 7 with a 780ti, 64GB RAM.
EDIT: It also fails with CPU. And In Max2015 it crashes when I try to render with RT...

Hello,

If you are using V-Ray 3.50.04 after you see the error message there should be a crash dump file named Vray.dmp in your temp folder (%temp% in windows explorer).
Could you send this file to our support or attach it here ?

Best regards,
Yavor

Couldn't get the attachment to work so here's a link to it. Thank you.
