Hi there,
This is about a fails that happens to me when I try to export a second time the same map. Uvmaps are done an I use he Multi Map Exporter. The second time I export there is a displacement in the texture, don´t match with the first time export
To me seems like the first one has more smoothed UVs or more density in the Uvs
Yes, you need to check the SmoothUV options you are using.
It looks like an issue with how ZBrush handles UV smoothing (which I can’t stand). Smoothuvs in Zbrush also smooths the UV borders so each time it ReUVs your object the borders get smoother and smoother. If you want consistent results its best to just turn off UV smoothing.
I dream of the day they fix the border edge issue, it makes the smoothuv option useless
