Thanks very much for the replies, and especially thanks for the tutorial.  I'll get to work on it asap.  :)

Okay - next question: the Poser textures tend to be pretty flat and unrealistic with the light sets that I've got; people tend to look as if they've been painted, rather than having 'natural' skin.  I know that Poser 4 limits the range of what I can do here, but does anyone know if there's a package anywhere I can use to give skin that realistic 'look'?  I'm talking here about, say, the reflection of perspiration, or the glow that skin reflects if a blue light is shined upon it - that sort of thing.  I'm pretty much an amateur here, so if there's a way to get these effects without downloading a package, please tell me.

Thanks.
