I'm very much a newbie when it comes to animation. I usually only use animation for dynamic cloth and hair. It was only DAZ's recent animated emoticon contest that got me to try animating a figure. This was a very quick 'n dirty job. You'll laugh when you hear how I created the motions. IK is off, because I'm used to stills, and the first thing I always do is turn IK off. I just took a half-dozen or so dance poses from DAZ's "Lone Dancer" pack, and applied them every five or ten frames. (That's why she looks a bit stiff, I expect. The Lone Dancer poses are for ballroom-style dancing.)

I rendered it at 388 x 445. I think it's 30 fps. It didn't really bog my machine down. The cloth took a bit of time, the hair was very fast (about a minute for 100 frames). (Kirwyn's Genesis Hair makes animating dynamic hair amazingly fast and easy.)

There's a larger version here:

It was done in Poser 5. I'm waiting for my P6 box. And looking forward to checking out the new Cloth and Hair Rooms. Supposedly, they are even faster in P6.
