This is not an unusual question. Both Poser and Daz|Studio have long been known as methods for creating outstanding looking still images, but not so much for animation.
Now, if you go onto any CG Animation forum on the net, you’ll likely find that lower-cost programs like Poser and Daz|Studio are not held in the same esteem as more expensive programs like Maya, 3DS MAX, Lightwave and Softimage. The perception is certainly out there that “good” animation needs expensive software and that the more expensive the software, the better the animation.
While it is true that the more expensive programs tend to have extensive toolsets, the capabilities of lower-cost programs have been expanding tremendously over the past few years. And for programs like Poser and Daz|Studio, they can indeed be used to make movies.
