Hi,
I’m getting strange black/white noise or dots in the Substance 3D Painter viewport, as shown in the screenshot. The same project looks normal on another computer.

Could this be related to the GPU, driver, or viewport settings? What should I check or compare between the two computers?

Painter version: Substance 3D Painter, version 12.1.3
Build 5709
GPU: AMD Radeon RX 5700 XT


OS: Windows 11 Version 25H2

    Hello.
    There are several possible causes for black spots to appear.


    First of all, I would like you to try updating your graphics card.


    I apologize for the speculation, but judging from the image, I feel like those black spots might be occurring during object baking.


    Best regards,
