I always set up textures & lighting (and do most of the modelling) in povray. Poser is great for manipulating models of people, but I've never really cared for it's lighting, textures or renderer. Povray can be pretty daunting to learn, but once you get used to the scripting language, it's really nice to be able to set up macros and loops to build libraries and do the more tedious modelling.
