Poser is fine for your illustration of campaign, if you used Vue it would take longer ot set up. But for fine art, if that's what you wish, Vue etc are totally out of Poser's league as renderers.
THough, in the end, it's always about the *artist*, not the apps, as beautiful work is most certianly done with Poser.
I use DAZ Studio, not poser. I like How it shows the scene much closer to the render while posing, unlike poser. But I'd not have time to use Vue even if I had the rpogram - I need about half a dozen pictures per week just for the curretn sessions, and more to catch up with past sessions.
