Displacement Artifacts

[system]

Hi
Im still pretty much a noob when it comes to zbrush so im hoping someone can help me.
I have a model that i created in XSI, I UV mapped it and then eported the OBJ to ZBrush.

Now in zbrush i can paint and sculpt perfectly and there are no issues, my issue starts as soon as click on “Create DispMap”
All of a sudden I get all these funky artifacts that band around the model, as you can see in the image, and they arent even on the UV seam lines!!!

So if anyone has any idea what on earth is going on, please let me know, ive really run out of ideas… :o

Thanks

To me, this looks clearly like a UV layout problem.
Try using ZBrush’s UV tiles (UV map > PUVTiles) to see if the problem still occurs.

…Or UV Master (which is an excellent choice all along).
