How about a seamless coating like milk or honey? I'm thinking of the liquid poured over the body so it would sort of cascade down. It would only cover part of the body and vary in thickness/transparency, perhaps with some rivulets and droplets towards the bottom and have to be colored of course. Possible? I'd like to see even a crude example. It occurs to me this technique might also be used to create a more realistic skin texture with pores, (though they'd have to be very tiny), scars, body hair a wet clothing look, etc. If it could be varied during an animation, you could create some interesting transformation effects. Using the second skin layer would have thehuge advantage of allowing you to use the effects on different body textures without modifying the textures themselves.
