Viewport IPR - frequent crashes on simple scenes

V-Ray V-Ray for 3ds Max Issues
1

I’m having frequent crashes with viewport IPR even on very simple scenes like a teapot on a plane + Vray plane light. This happens when I navigate a bit and then I turn off viewport IPR by clicking on the shading mode of the viewport and then clicking on V-Ray IPR.

Attached below is the Max scene and a video I recorded. I just sent these files to support along with 2 crash dumps from that scene. It’s an update to ticket number 496-083-703.

Yes, Vray Next Update 1. The viewport IPR feature is not available in older versions of Vray. It’s the CPU renderer, not GPU.
