This morph was very simply. "Mag base" has default position. "Mag" is ztran=-0,074 rest parameters default. "Mag zone" is scale 1,2 xscale=130 yscale=100 zscale=110 xtrans=0,016 ytrans=0,707 ztrans=0,032 no rotation.

If you like result make new magnet. copy-paste parameters and change "mag zone" xtrans=+0,016

Now "create morph target", check if all works well (set Mag1 and Mag2 = 0 your morph =1), delete magnets and add figure with new morph to library.

I think that in Zbrush you can obtain better morphs but with poser tools making simply morphs is much easier. Moreover it is not so dangerous - your geometry folder is safe ;)

I wanted to make tutorial about it, but my last tutorial "pending approval" almost 2 weeks and I'm affraid that Michael lost his hairs because of aging before you can read it.
