I touch up poke-thru and creased joints. I may soften the hair, and harsh lines and shadows. Often I do multi-pass renders and composite them. I usually render the same scene twice, with and without raytraced shadows. Then I composite and use erase tool to blend them. I manually blur the distance, then do the rub-thru. I may use several blur levels to create defocus. And I add motion-blur manually, with layers. I use python quite a bit. MetaForm and Particles2 are awesome. Do Purists use these? Or are they anti-purist cheating? I do not know, nor do I care. I use them, I like them, they work for me. I DO try to do as much as economically feasible within Poser, like rays, plasma, explosions, etc. So I strive to be a purist, but do not expect to be one. There are a few renders in my gallery that use the above techniques and tools. If an artist wants to use Poser ONLY, that is their business. They are neither right nor wrong. Same goes for multi-tool users. Do what you must to get the image the way you want it to be.
