The general habit in setting up a prop for use in Poser (via UVmapper, for instance)

is to leave out the 'vn' stuff  (the normals). 

So if you just copy the lines from the PP2 directly to an OBJ file, you'll have the

same "lightweight" form.  But when you export the OBJ out of Poser, Poser will

re-insert the 'vn' stuff, giving a "heavier" file with info that Poser doesn't need.
