DS 4.21_05 worked like a charme. Iray rendering hasn't been a problem. The new IRAY in 4.22 build doesn't work. Render screen remains empty.

Oooopsy Driver problem.
for anyone having a similar problem, make sure to have the latest Nvidea GPU driver installed.
My Nvidia driver is 2 days old. The iRay render doesn't work :-(
How can I get the previous version?
This is the 3rd time the Daz update sucks. Thank you, never more
What is your GPU? What happens when you try to render? have you checked the log (Help>Troubleshooting>View Log File)?
This worked for me too.
I guess no one have that problem anymore but I haven't found any solution. Always renders just blank image and iray preview is infinitely running with smooth shading. All drivers for my geforce rtx 4060 are up to date and I got no issues to render in blender or marmoset.

In 4.22 or in the current version?
4.24.0.4 (64bit)
OK, then what is your driver version - and is it Studio or Game Ready?
NVIDIA Studio driver
Version: 591.74 - Released : Mon, Jan 5, 2026
It might be worth trying an older driver, if you don't have somethign else requiiring the newer. I am having no issues with 576.88
