Applied Daz 4.9 Update: Iray Renders now Black

in Technical Help (nuts n bolts)

I finally decided to installed the new Daz Update through install manager because Daz had started crashing a lot.

Now every render I do is completely black.  This is even with saved scenes I had successfully rendered before the update.  Reality works; 3Delight Works;  Iray, I'm either getting a completely black render, or completely transparent checkered pattern with no objects in the scene whatsoever.  I changed the environment settings.  Tone Mapping is still at 100%.   I can not figure this out.

Has anyone else had this problem after installing the Update, and if that is the problem is there anyway to reinstall the Daz 4.9 before the most recent update?

    Does this only hapen with a GPU render or a CPU-only render too?

    If only GPU, do you have the latest (or at least a recent) driver installed for your GPU? DS 4.9.3.166 upped the requirement to a newer driver than the previous DS version. You should see an error message in the log file if the GPU can't be used.

    ETA: This thread gives more info - here's a relevent post: http://www.daz3d.com/forums/discussion/comment/1988621/#Comment_1988621

    I'll check that out.  I'd been using GPU.

    Installing the new Nvidia driver seems to have worked.  That update was rather old and seemed to me at the time to only pertain to gamers, so I passed on it, but it looks like I needed it after all.

    Odds are I'm going to be in the market for a new system if the next Daz upgrade results in the same problem.
