Unusual Artifact by Create NormalMap

ZBrush Usage Questions
#1

Greetings everyone,

I’ve been working on a hat, modeled and Unwrapped it in Maya 2014. Imported it ZBrush 4R7 sculpted it and when hitting create NormalMap it works fine but there is a huge artifact in it. I triple checked my model and can’t fine the source also tried it with and without Adaptive in different maps sizes and it didn’t make any difference. Sadly enough I figured that out as I was done with sculpting and don’t want to start over when I can fix it some how.

Here the normal map:

And here the .ma file I exported from Maya to ZBrush (manually):

I Check the normals, completely quad-based and no manifold geometry. Also I unwrapped it manually

Thanks in advance.

ZBrush will do that if your UVs extend right to the edge of the UV space. Shrink them down a touch and all should be well.

Thanks that was a noob fail and I can’t belive I missed that all the time. That solved my problem.
