I don’t think you could make a living at it … maybe a little extra pocket money if your products were good and distinctive
I don’t know where Poser renders end up, other than on Renderosity … I think organic models are still IN for that kind of stuff [as a side note, the skin always folds funny around the shoulders, did they ever fix that?]
As for other types of models, the markets would be games and (rarely) movies … both iffy propositions money-wise … but if you know you are good, build up a portfolio and send it around … invest in a website and use the right keywords on the front page so that Google etc. will index it … science fiction book publishers are another market, e.g. DAW and TOR, but of course there are a limited number of slots per year (in the hundreds, but still there is a lot of competition)
at gummie – oh come on, there must be room in the Poser world for “Zebula” or “Jocasta” or “Humphrey”
