The poseable/animatable figures and animals sold at Cornucopia3D do NOT require Poser. In fact, they cannot be used with poser as their rigging is set up for Vue and they are delivered only as .vob

I have a number of them and they are quite easy to use. You select the figure and then the skeleton. Now I usually switch the gadget to local mode and rotation. Then you can simply select each bone in the display port and adjust the rotations to get the pose you want. I use the motions that are available at C3D as a quick starting point. Feel free to ask if you need more detail.

The same approach also works for figures that I export from DAZ Studio as collada.
