Hi,
It can be done but there is a "liltle" preparation involved.
Zbrush don't like the standard uv mapping of poser figures,
this is not a problem for morphing or smoothing but it is for displacement creation.
You have to adjust the uv's , that can be done in different way's.
You have to remove all overlapping and inverted uv's and next you have to make a choice of 
putting the uv's in multiple uv tiles or fitting all the uv's in one uv space.
I use this "method" with 3dsmax and this works ok , so it should also works for vue.
