Sometimes all you need to do is just split the verts (uv mapper) and all will settle down and look as it should.

won't work on this one, mores the pity... if you see on each face with an arch or window, there's no edges connecting the vertices... so, when Poser (and a quite a few other programs) try to use it, they 'web' over the hole closing it. the only way to really sort the problem out is to add edges so the program can handle the hole properly.
