Its the Holy Grail of all clothing modelers. It is a utility that examines the morphs present in a base figure then constructs the equivalent morphs in the figure's clothing. The Runtime computer code translated into English goes something like this....

"Ahhh I see that when I tweak this morph dial Mike's chesticles move over and up a bit....... Now let me see what part of his attire I need to move to keep him decent...... OK that looks good let me make a note of what I did."

It then saves these new morphs within the clothing CR2.
