well, I’ve imported in Z-brush a model after set up the UVs in maya. Now after I’ve worked for hours with this model the result of z-mapper when I try to create normal maps is this!!!
all detail lost, and this confused result appear, why???
Some other attempts and I had understand that the problem is to use z-mapper with polygroups! Any advice? I simply click on “UV groups” and turn on the wire-frame, then ctrl_shift on one piece of geometry and use zmapper 
thank you
and the uv’s are ok, because for experiment I have used a simple cube and placed each single face in a 0-1 space, then I’ve exported in zbrush and increase the number of polys.
I’ve attached an example file, let me know if it works with you.
thanks!

ZMapper requires that you split the model into subtools for each mapping region. You then need to generate the normal maps one at a time, for each subtool.
