My name is Paul, I live in Adelaide (Australia), and I'm just about to hit the big four-o. I spend way too much time using 3d applications like Poser and ZBrush2. Being a (no-postwork) realism nut, I have developed a number of realism tools for Poser, and the skin shader scripts for Poser are avaialble here at Renderosity.BIOA couple of useful links...
