Zbrush normal map in blender has artefacts along edges

[dezertiss]

Hi,
I have an issue with normal map from zbrush. It’s in udim. On some edges there is a pinch effect. I don’t know how to solve this issue.

What does your normal map look like? Does it also contain these pinches?

[dezertiss]

Yes

As the pinches are in the Zbrush normal map output, I suggest solving the issue in Zbrush rather than trying to fix it in Blender.

[dezertiss]

Yes I believe it too

[dezertiss]

It was because I didn’t used “smooth uv” in zbrush.

Actually I’m here. It’s still a wip.
