Substance painter generates artefacts when baking AO map

antonon178 · Aug 17 2024

Hi guys)

Could anyone explain-what causes these damn artefacts when baking AO map in SP?They are appearing where the seams are located.I changed dialation width a few times but it did not help.

What adjustments do I have to do in substance painter?

Hi)Using photoshop or other third program-is not an option for me)Changing dialation value in SP does not help either.What else should I try in substance painter?Thank you for responding Eric Chadwick)

See this recent Topic, maybe the same problem & solution https://polycount.com/discussion/235859/issue-with-padding-on-diffuse-texture

Try changing the UV padding in SubstancePainter's TextureSettings to UV Space Naighbor.

The default is 3D Space Naighbor, but this may cause unintended UV borders to appear.

I would be happy if this helps.

Hi guys)I do not know how it works,but when I checked "apply diffusion" option before baking-the problem has gone)

diffusion is padding but with no limit so if padding wasn't working, the value wasn't high enough.

you'd want a minimum of 32 pixels at 4k if you're going to use padding
