I was just checking this out today, and I realized that at no point did I mention that if you are converting something that can use LF's MFD or another LF donor more or less exactly, you can simply load the donor into your scene and use the fitting room, with your un-zeroed obj as the object and your zeroed donor as the goal. There is some flexibility here. For example, if you want a garment with hanging front and back panels to auto group only to the front and back skirt controls, uncheck the center, left, and right skirt handles when you create the new figure. If there is a really long train, you can try bending the rear control on MFD backward to overlap and then use MFD as the goal un-zeroed. You can copy the morphs in the fitting room or after the garment is rigged.

By the way, Susie's Rags has an excellent LF native donor rig for skirts down to knee length.

I also realized that these tutorials apply to Poser 11 Pro, as I understand that one of the "improvements" in Poser 12 is the elimination of the simple tab for adding new textures to clothing. You now have to screw around with nodes.
