IF you are making an item of conforming clothing (not an original figure) the easiest way to get Poser to respect the groups and get the bones right is to stay out of the set-up room and open up a text editor. Simply put, create a "stripped" version of the base figure's cr2 (several recent figures, like the GIRL, include a file like this in the download), and point it towards your new object file by changing two lines. Load it into Poser, tweak the joint params a little, and you are done. For an original figure I've had some luck using Poser's Grouping Tool to spawn groups as objects, then the Heirchary Editor to put them in the right order and create a new figure. Using phi import can make this faster -- and you can create the dead-simple phi files on any text editor in a couple of minutes -- but Poser doesn't always play nice with this proccess.
