Larger Files Will Not Render Without Enabling CPU

in Daz Studio Discussion

I've updated Daz to the most recent download.

I'm running:

13th gen intel core i7-13700F 2.10ghz

32gb RAM

Windows Home 1123H2

NVIDIA GeForce RTX 4070

After updating Daz, I opened an older, large file, attempted to render in IRAY, the render runs but it never gets to 1 iteration before the render just quits and gives an empty image. I render with the CPU unchecked and let the GPU do all the work, but now I'm finding, for larger files, it will not render unless I enable the CPU and that seems to ignore the GPU completely. The task manager shows the CPU at 100% and the GPU at 0%. I haven't had this issue with smaller renders, just larger files.

i am accepting all ideas and suggestions. Thank you in advance.

    Different versions of Iray require different amounts of memory, generally newer more than older. It is likely that your large scenes (just) fitted before and now don't. Reducing texture sizes (e.g. with Scene Optimiser or just manually) where possible may fix this.

    windows home might not handle things the same as pro?

    It seems that the scene data exceeded your GPU's memory capacity.
    Daz Studio isn't very good at freeing up GPU memory, so when rendering large scenes, it's advisable to restart Daz Studio to ensure the GPU memory is fully cleared before starting the render.
    If the scene still exceeds the GPU's memory even after restarting, as Richard suggested, you might want to try reducing the scene data using a tool like Scene Optimizer.
    Another option is to utilize a remote Iray Server such as Boost for Daz.

    will the 4070 work with older dazs? 
    And whats the difference in output between the 4070 on daz 423 or daz 421?

    So it may have been an issue with the file itself, I recreated it from scratch without touching the textures or resolution and it's rednering, in Iray like normal.

    So far Win 11 Home and the 4070 seem to be working okay, which is great because I didn't want to upgrade either.

     

    Thank you all,

    There have been reports that 4.23 has issues opening old scenes, while new ones work fine. This may be another case. Having to recreate the whole scene in 4.23 to make it work is of course not acceptable, unless the issue is limited to this single large scene, in which case it may be a corrupted file. Let us know so this could help the daz developers.
