When making shoes you only need to have the morphs in affectEd groups, toe foot shin depending on the style and how high they go uptithe leg, shin and/or the thigh. Actually you could get awaytwitch just a foot group for the shoe as long as it fits no higher than the shin.

Using Morph ClothsI uses a mathematical formula to move thevertices in you shoe based on the difference between the unmorphed base figure and it's own morphdata, therefore it is not an exact 'copy' of the morph but an approximation based on math. So you could leave all of the empty channels, the ones that start with PBMCC in if you want or just deselect them before transfer the mophs unless they have active morphs ijested into the base figure at the time you use Morph Cloths, they are basically useless.

I'm on my iPad at the moment so forgive misspellings I will be back on my regular computer tomorrow if you need more help.
