had hoped I could say "ha the mistake is there" but I cant !! it all looks ok to me (I'm NOT expert) but thats about the same way I do it

what I dont understand is the preview looks right so why not the render?

saw this on BA too so hope some one with more ideas helps you

 

ps what hair is it ? I might have it but not bought any poser stuff for a yr or 3 so its a long shot
