More on trans maps: Poser will render the black areas in the trans map as transparent and the white as opaque. Shades of grey in between will render as semi-transparent. It is usually used for eyelashes, hair and clothes with transparent parts (lace etc). A trans map is easy to make in a picture editing software (PhotoShop, PaintShop Pro etc) by just turning a normal image of e.g. lace into a greyscale image.
