What hasn't been noted here so far is that the texture map you are working with needs to be as big as possible. Poser relies on a three key areas to refelect the level of realism you seek: Texture, Bump, and Lighting, in increasing order of importance. Texture and bump maps need to be large -- serious photorealistic starts at 1500 bare minimum, and 2000 and 2500 are considered the essentials. Lots of excellent tuorials on lighting out there. To create ourselves in poser, a group of us created 1500 pixeltexture maps and 2500 pixel bit maps, all at 150 dpi resolution, and got astonishing results. But, boy, did they take a lot of time to load!

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
