**Issue Description: d5 RENDER crashes after 31 sportlights (or any other light)
Screenshots/Videos Description:

Hi community!, I’m new here in the forum.

I’m having issues with D5 usingo lights after 31 lights (image attached) the software is crashed and closed, it doesn’t matter which light is used. I tried duplicating other (used) lights on the project but it happens the same issue

I’m using Rhino 7 files and every model inside the scene is imported individually. I’m not using rhino sync in this project.

Does anyone know how to fix this light problem?

Thanks a lot!

Hi @cythsylean ,sorry for the late reply. We have checked the logs and found that this should be an error caused by the latest graphics driver version (526.47), please try to go to the Geforce website and download an earlier driver version (e.g. 516, 517), please try and let us know how it goes. Thanks [image]

Hi Lia!, thanks for help me with this problem, let me try reinstalling the previous GPU driver version, beacuse after that anything goes wrong with D5. however I’ll send you an emai with de zziplog file.

This solution works fine, the newest GPU driver vesion of Nvidia (526.47) doesn’t work well, actually when I updated it, D5 had issues specially with lights (in my case).

I hope this error will help you to fix it in the future updates, Thanks support team!
