Iray suddenly stopped working in viewports?

Hi all,

 

New user to the studio, and I am liking it so far, but something very strange suddenly happened this evening.  In the middle of playing with a scene, my iray render mode option stopped working.  It seems to be stuck on the initial smooth shaded render that you always get at the very start, and although the little yellow bar is frantically filling over and over, it never progresses.  I've tried switching the mode from photoreal to interactive and back again, to no avail.  the other modes all work, as does actually rendering, but nothing in the viewports, which sucks for trying to light stuff.

 

has anyone else seen this issue?

Did/does restarting DS help?

no, it didn't, I'm afraid.

 

after powring down my pc and then coming back to it in the morning, everything was back to normal, but I now exist in a state of fear that it will break again.

If Iray runs out of memory on the GPU it will need at least a rstart of DS, and sometimes a system restart, to free the memory up. Itv appears that, at least in this case, you were in the group that need a system restart.
