Sigh, even though I achieved lift off on my test render, I'm not actually sure how I would create shader presets using the lip mask. I suppose the only way to make it so that lipsticks can 'stack' on top of face maps with different makeups is to use layer transparency when I'm making the maps in the first place.......
