Hi 3DNeo !

Rebelmommy has published a nice tutorial here:

The easiest way to make a texture for V4 is to purchase a merchant ressource for V4 - so you won't be bothered with seams , they are really a  headache - then  use it as a base,  modify it with your own photo ressources (you don't necessarily need your photos , you may also purchase additional photos from 3d.sk for ex.) or add make-ups also available as merchant ressources .
