Quote - Do you mean that it is not necessary to create the morph for the clothing to work with V4.1 magnetize pose?  That's simple!

As Richard says the supplied magnets only do the figure's JCMs.

You can however get a magnet set that help you create matching (non-JCM) morphs for clothing -> http://www.daz3d.com/i.x/shop/itemdetails/-/?item=4895
