I did the match preview window, and I also set the camera to what I wanted in poser, and then used the poser setting in the GUI, I also resaved the scene under a new name, and it still doesn't work. I am going to save the props out and reload everything and see if that works. It doesn't seem to be an issue with the exporter or the gui or Lux, it is something weird with the pz3 file I guess. I am having no problems with my own scenes I have saved and exported to Lux.
