Just after posting here I went to the official DAZ Studio forum and found the information I've been needing, the thread is titled "Displacement & splitting vertices" http://forum.daz3d.com/viewtopic.php?p=197977#197977 I hope the address will work. Basicaly both Poser and Studio automatically smooth models. The only way to avoid this is either add a lot of extra lines at the area you don't want smoothed or split the vertices. Splitting the vertices means breaking the model into individual faces where ever you don't want smoothing. The thread is mostly about how this interfers in using Studio's displacement feature but it still may be worth taking a look at.
