DS will IMPORT (go to FILE, IMPORT) and you will see all your favorite Poser file formats. While there may be "issues" still with other imports, the Poser Light Models (*.lt2) always seem to import without any problems at all. So I IMMEDATELY import my favorite light set into DS after loading a model- usually via the Content Menu, which has been working fine for me. In fact- you can load the lights that way ALSO. I have been using my favorite Poser-Tweaked pastel lights and DAZ Global Lights, and you will see all your scenes look much better! But you will also have to reduce the Diffuse and Specular settings way down or your models will look too bright.
