Textured export works if you choose Textures: From Materials (for simplified texture workflow) or Textures: Full Render (with shading and lighting). If your model cannot be exported either way, please send me the file to adominec@gmail.com so that I can provide a fix.
This is just what i needed! But if you could add textures to the papercraft (for exaple, a car with details, but it will go out as a white object :/). Still, a very good addon!
