in Technical Help (nuts n bolts)

Just updated to 4.2 (dumb I know) and now iray preview won't load (endless cycling bar on loading tab). test renders result in a near instantaneous completion with a black screen. The previous sttings seem normal otrherwise.  Any clues as to make things function properly? Thanks in advance.

    I've just heard that mesh lights don't work in 4.20.  Are you relying on mesh lights to illuminate in Iray?

    Mesh lights or Ghost Lights? The original Ghost Lights product has an issue with later versions of Daz Studio/Iray.

    Has the OP made sure they have required video driver installed? Ihave just upgraded to 4.20 and I updated graphics driver first to 473.04 I think it was.

    Loaded and ran the render test with Daz's default lighting...no joy.

    I'll update GPU drivers also...

    Updated drivers did the trick.
