How to keep the defaust UV from MaYa in ZB ?
When I create the displacement map, Zbrush will ask for the New UV set but I want to use the default UV that I’ve made from maya how can I do ? 
Thank you.
That’s strange, because ZBrush will detect the existing UV form the model you imported. Can you do some “New From UV Check” from the texture palette and see what happen?..if it’s showing the same UV as you have in Maya, supposedly there’s no problem in generating disp map. But if there’s noting/ bunch of ugly overlapping UV, means that your UV was not export correctly from Maya.
I’m not a Maya user myself, but in Max/ Lightwave, it works fine.
