Alas, the dress is all in one piece. I was thinking of "fudging" it by using black and white pixels alternated on the skirt portion (I use this technique to make boxes translucent in web design) but I was hoping someone had a more elegant solution for me. ;) I don't understand remapping all too well.. I suppose I could redo the materials using the grouping tool in Poser to separate out the top portion?

For my image to work I need to be able to see the legs of the bodysuit through the skirt.
