Render Problem again

Bootwink

I had this problem before.  Then before I even  got a respome my renders started working. I've been rendering things for a few months now no major problems.  now all of a sudden I can't get a render, it comes out blank, with a disciption to name it and where to place it, and it is blank. I can here it going threw the Porcess of rendering, but real quick it pops up a with blank slate, I don't remember why it started working before, but I can't get it to Render, not even in the active frame where it will render half the time. I use Iray all the time for my renders. I have no Idea what happened. 3 hours of trying to render again, I don't think there is a bug in my program, because it was corrected the other time, now it's doing the same thing again. I know it's me, but I don't know what I'm missing.

At a guess Windows Update has rolled you back to an older version of the driver and it isn't supported by the version of Iray in 4.12.0.86. You can check the driver version by right-clicking on the desktop and selecting nVidia Control Panel; Iray now needs 430.86 or later.
