Will a clothing figure made in the setup room using the bones from a pre-existing model such as Posette conform to said model?????

Yes - in the Setup Room you add the Posette figure's "skeleton" to the clothes mesh. Then you delete all the bones representing body parts that Posette has, but the clothes figures has not, such as fingers etc. When the skeleton's body parts match those of the clothing mesh, you're ready (provided you've already grouped your clothing model, otherwise you have to do that while in the setup room). One important point : the Posette figure (and the other human figures) have some "starter settings" in their joint, so before you use an existing figure as a skeleton for a new one, pull that figure into Poser, turn off IK and use Joint Editor's "Zero Figure" to make sure all settings are set to zero. Save the zeroed figure with a new name, like PosetteZero, and use PosetteZero's skeleton for your new clothes figure. If you don't - well, try it and see why. Have fun,

thanks.
