the above is what the poser edge-blend shader looks like in post-process, but bill and olivier have shaders for this in poser, without any need for photoshop.  oops! just noticed the OP doesn't need linework.  that will make it very easy in poser, as it's not a cartoon style.  that's the hardest thing to learn in cartoons - how to do the inking.  there are dozens of books, but none of them actually give away the secrets to dramatic linework, fortunately.  still need humans for that :lol:
