AO baking error in substance painter

I got an error when doing bake ambient occlusion.
the AO display looks inappropriate, with strange patterns, completely unable to detect the angles on my object. On all the 3D objects that I use, the results are the same.
Here I give an example of only using a cube because the results will be more certain, it is impossible to experience a wrong backface or UV. but the result is still like this.

what do I have to do ? This bug occurred suddenly.

    Any update on this issue..??
    Latest Nvidia Studio Driver (576.52) doesn't seem to fix it either.

    Hi @Cyril Dellenbach 

    I have tried both the current studio driver (576.02) and game ready driver(576.40).. still the issue is there.

      Hi @PSKAtelier,

       

      Thank you for the report and the screenshot!

       

      I'm sharing the problem with the team, so we can reproduce the bug and share data with Nvidia. Can I also have your GPU info? 

       

      In the meantime, I advise you to try latest drivers updates and let us know if one seems to fix the problem.

       

      Best regards,

      Yup this issue is still not fixed for me even after the nvidia 576.02 driver update.
      I'm using substance 3D painter 2024 version 10.1.2
      Both highpoly and lowpoly were exported from blender
      bake parameters :
      resolution - 4096
      Average normals - Off
      AntiAliasing - 16x
      Match by mesh name.
      (This occurs While baking AO, Curvature and Thickness)

      Hi @Max28617167iqjd,

       

      Can you let us know which version of Painter you're using? In addition, what are your baking parameters (Resolution, anti-aliasing, etc.)?

       

      I'd also appreciate a screenshot of the issue.

        Not what I said, I did not use the "Use Low Poly Mesh as High Poly Mesh" checkbox, I added the Low Poly fbx mesh to the "High Definition Meshes" list. The same low poly mesh I am using for the project is being used again in the High Definition Meshes lister.
