    hello, I installed nvidia cuda toolkit v10 and the iray render worked.

    I leave the link

    It doesn't work for me.
    I tried to install it, but it's still the same, black or checkered renders :(
    (In fact I had more recent drivers, physix and geforce experience installed, so it only installed cuda toolkit, which is a development toolkit so i don't think it has anything to do with daz studio working or not?)
    Thanks anyway. Any other suggestion?

     

    EDIT: Wait, I may have written too soon. After restarting Daz Studio, and after a few renders, it seems Iray works fine. Fingers crossed. So thank you!

    Great, it works perfect for me, just install Cuda 10.1

    I had problems with the CUDA engine. My old Nvidia GeForce GT 540M was not detected. I simply replaced the Libs folder and the dzirayrenderer.dll file for Daz version 4.10 in the 4.12 installation. And to work... wink

    I had the same problem with v4.12 on a Gcloud compute virtual workstation.  The solution was to download & intall Cuda toolkit 10.2 (and its dependencies like Visual Studio C++ workflow) and then install the matching GRID GPU driver from the Google cloud archive.  Note that for the GPUs provided by GCP virtual machines, the latest drivers supplied by NVidia are compute-oriented and will result in the GPU entering TCC mode which breaks iRay.  You need the relevant GRID driver for your GPU as provided by your cloud provider (NVidia doesn't supply them directly to consumers) and the right version of toolkit (not 100% sure if that is a requirement - better safe than sorry).  The WDDM GRID driver should remove the OpenGL 1.1 restriction when working over RDP and CUDA 10.2 will make the GPU visible to iRay.

    That's how I was able to render on a VM with a GPU attached.  It took me a few hours to figure all this out, so I hope that it helps someone.
