Yes.. most people do the morph fits by hand in a 3d modelling application, and add them as full body morphs so they superconform, and apply when the main figure also changes as well.

Morphing clothes is a quick in dirty possible solution, much like using lyrra's magnet fits at daz, and spawing morph targets from applying those.

Both methods can work, but IMHO you still need to load th eresults into a modeler, and make minor adjustments. They are both good as end user tools, but not as complete commercail replacements for doing the morphs by hand.

Way too many people take way too many things way too seriously.
