uv Problem

I transferred back my obj from zbrush to maya, i made an adjustment on UV arrangement & the size of uv for my male character

I follow http://www.pixologic.com/docs/index.php/ZBrush_To_Maya_Displacement_Guide

after i transferred back to zbrush to recreate the normal mapping i created its follow the previous UV not the new one, any idead to change to new uv?
do i need re culpt my character?

If you import the version with the new UV mapping into level 1 of the ZBrush model the UV’s should update. I’m guessing that whatever steps you did didn’t actually save the UV’s, or you accidentally imported the original version back into ZBrush rather than the newly mapped version.
