I started playing around with poser 6 a while back just for grins and kicked these facial expressions out fairly quickly. Im still learning some of the more complex features. I've started a blog page at Comcast.net with some photos uploaded. Ill try and load more later this morning. Oh, the address is:http://home.comcast.net/~nannerfkm/site/?/photos/
Anything in particular you interested in? If you can describe it, I can try to reproduce it. No promises on the result though....I aint no stinking artist. Yes, i have a day job :-)
I'm guessing you can use any picture for these. Just copy a picture of your girlfriend on top of one of the default ones (renamed of course. Prolly should put it in its own directory). I just copied one of my pics (kaza) in the avatar folder with her name and she was picked up as a player charactor choice so either the program is very forgiving or I just managed to get the size right out of shear luck :-0
PS: Suggest you use the avatar folder in your Documents folder, not in the one under Program files.
