Zanzo,

Thanks for posting that. It is quite a complex procedure but fivecat clearly made it work, and I take my hat off to him/her for working that out.  I haven't tried it so I can't comment on how easy it might get with practice.

If I was going to try it I would do a really basic morph in Zbrush to start, and see if I was following  the procedure right, and getting predictable results, rather than spending a lot of time morphing and then finding I missed a step or misunderstood the procedue and all my careful morphing effort was wasted.
