Okay, if I understand, you have an .obj file that you want to turn into a Poser figure, is that correct? If that's the case, then you'll need to group the object in Max, UVMapper, or Poser (whatever is easiest for you) and create a .cr2 file to make it posable. There are tutorials out there to assist with this. (.pz2 files are prop files and MAT files. .cr2 files are figure files.) MAT files only affect what textures are loaded onto the object and can only be used (without some hacking) on posable figures. Hope this helps.
