Pixelated brush stroke on the 3D model

Question

Hi, I have an issue with the painting on my 3D model. When I paint on the model the stroke is very pixelated no matter how big the UVs are or how high the resolution is. I tried to re cut the UVs with a lot more UDIMS and it kind of worked but it'll make my model way heavier, so i want to know if there's a better way to make the brush look less pixelated without having that much UDIMS.

Thanks,

Hi Jessica,

Thanks for the question.

When working with Substance 3D Painter, you're always painting on UVs. Therefore, the strokes of the brush will always be defined by the resolution of the Texture set. The more pixels you'll have, the smoother the stroke.

Splitting the UVs in several UDIM can be a solution (each UV island will have more space, so more pixels), but in your case, I think you didn't gain that much space, at least for the head of the character. Therefore, I would rather advise you to switch the resolution from 2K to 4K. If already in 4K, you can export the textures in 8K, but not visualize them in the viewport.

Regards,
