or.... have the doc window square 300X300 600X600 whatever.. doesn't really mattre. position the main camera to what you want in the thumb. render with antialias on in the doc window. paste that onto the background. select a "hand camera" doesn't mattre which one... dolly the figure out of the picture... resave the figure selecting only the dress in this case.. Ta hagen das.. reasonably simple method to get a decent thumb within poser.. hope this helped a little Cheers
