I have updated and now I can't render in iRay. I have loaded a scene that has rendered well in the past, but now I don't get anything. Help!

    Two things come to mind: if you have an nVidea card, have you updated to the latest driver?

    if you don't have a card, have you selected CPU as render engine? The update might have unswitched the setting from the saved scene.

    I am going to have to look into the graphics drivers actually. I noticed in the log that it mentions no device found, so I turned the CPU back on again in the render settings and it started to work again, allbeit slowly.

    wish me luck

    Yes, the new Iray version in the new D|S update needs a "recent" driver version, otherwise Iray can't use the card at all. I think it's been mentioned before that the cutoff version seems to be 372.

    Note, though, that older cards (although still capable of running Iray until this update) might not be able to use the most current driver; my card is in the old-and-creaky-but-still-works category, was never able to do Iray, and can't use a driver newer than 342.

    I ran into this same issue with the latest update as well. I was using driver 362.00 (happily, I might add, as it was extremely stable), and had to update to a newer post-372 driver. Now I am facing the same dilema I was faced with last year; finding a stable driver that doesn't crash under harder renders.

    I've tried letting Windows choose the driver, and it chose 376.53. Iray works now, but now is not stable... I've been running into the same I used to have with past drivers; my GPU's sometimes decide to stop working and randomly kick over to CPU-only (even on simple scenes). So it looks like I'll have to continue searching for a stable driver.

    Nvidia drivers are hit and miss for me. One will work but the next won't and I have to roll back until the next is released.

    372.90 is stable for me and works without compliant in 4.9.3.166

    I've just downloaded and installed the Geforce experience software (which I could have sworn I had installed a few months ago) and I found that my drivers were 368.69 which seems a little out of date. So, I'm just downloading a further 350MB file to bring me up to speed. I'm going to pray that this work and makes my PC work better with DAZ again. 

    wish me luck!

    Hi there

    Personally I use 373.06 which works flawlessly on my GTX1080 or Titan X

    Hope this helps

    Thanks,Jura
