Yes you can - take your example of a haunted house. I have such a model which currently it's a static prop. Load the OBJ into UVMapper, locate the bits that make up the window(s), assign them to new groups. Save the OBJ and create a poser figure with those groups as body parts. A good poser figure tutorial is here.. http://www.cocs.com/poser/makingfigure1.htm For the freebie house, click the banner and select freebies on the site.

Pinky - you left the lens cap of your mind on again.
