Easiest way, at least for me is just cut your object up in your modeling program with the right Poser names, they save the object and point a suitable CR2 at it. If the dress (or whatever) has been fitted over the figure you can use the figure's parts to work out where each part is cut. But- dresses can't have shins, at least shins that are in mesh. While you can put a weld command to weld the joint, you can't make such a dress bend the shins separatly, the other shin isn't in the hiearchy for that shin, so the bending and whatever doesn't work on it. So what you have is a dress that can be sat it, but will only work for poses where both shins move togeather - I would guess you are aware of that, though.
