Weird artifacts when baking importing from Maya

Hi

 

I'm importing some 3d objects from Maya to Substance Painter but whenever I bake the textures, Ambient Oclussion bakes some weird artifacts. I though it was because some issue with my models, but I've just tried with a simple box with an automatic mapping and the issue remains. 

 

Maya:

 

Substance Painter:

 

 

 

I even uninstall and install again the program but the issue remains.

 

Any help here?

 

Thanks in advance

Tried with --force-optix parameter and worked as a charm! Thank you!

    Hi @victor_sanchez9390,

     

    Unfortunately, this is an issue we're facing with Nvidia latest driver.

     

    • You can try this fix, but from users feedback it doesn't work for everyone.
    • You can also try to disable the GPU Raytracing (Edit > Settings > General > Baking options > Enable GPU Raytracing) 
    • Utlimately, you can rollback to a previous driver version

     

    For the information, we're currently in discussion with Nvidia to find a fix a soon as possible.

     

    Best regards,
