Please update your GPU driver to the most recent. At the moment that would be NVIDIA Studio Driver | 551.86 | Windows 10 64-bit, Windows 11 | NVIDIA . When you start the installer make sure to choos Custom/Advanced installation and check the Clean Install from the next page.

Thanks a lot Nathan, but still the same. It is really weird i worked several times with cosmos bricks and never happened before.

Is the model far from origin? If so try moving it to around world origin and see if that helps

it is centered yes, is it any way to open the file without previous materials and reset everything to initial config?

Perhaps you can share the model for further investigation? You can share it with us confidentially using Rhino - Upload to Support . ZIP the 3dm file with all support files. I’ll have a look after the weekend.

Hello Nathan, the problem is solved. Instead of trying to fix the model, or whatever it was, I have copied the objects to a clean file, no materials, textures or lights. Then I have applied the same materials and lights in teh new file and everthing work fine. Even the rendering is much faster now which make me think that maybe something was creating conflicts when processing the graphics. Thanks a lot for your help. Best regards.
