Real Skin Shader is cheaper, and works just fine with ALL millenium human figures, Vicky 2 and Vicky3 inclusive. I've used it on some of my gallery images and it does quite well. The Unimesh Realism Kit is better, but works only on DAZ Unimesh figures (e.g. Vicky 3, Micheal 3, Aiko 3). It will NOT work on Vicky 2 or Michael 2, and it's more expensive. Hope this helps.
