All three of the above characters use the exact same textures and shaders!  The differences in what would ordinarily be determined by texture sets and/or material presets are instead determined entirely by spinning dials, just like geometry-based features!  That's the experimental new approach to character creation taken with Pulcherrima and Friends for La Femme and L'Homme, a unique texture and shader package for Poser's flagship figures!  No more fixed presets!  Features such as skin color, eye color, hair (i.e. eyebrow, pubic, etc) color can all be varied along a continuous spectrum just by spinning dials, offering a virtually endless range of combinations!  I hope you'll join me in experimenting with this novel way of generating diverse characters from the same base figures!

I want to see the palms and soles for very dark skinned characters.  I have always had a problem with non-texture-based shaders when it comes to those parts of the figure.

There's actually a dial for that very feature!  The palms (and soles) can either be the same color as the rest of the figure or they can look like this (or anywhere in between):

That's just a quick sample (default scene, default SuperFly settings).  If you want a more polished sample, just let me know!
