For modeling skulls, bones and skeletons in general, hamapatch was, and IMHO still is, a very good free software.
Unfortunately it has, for the most part, disappeared from the internet, since the last version was released:
31. December 2004. (hamaPatch 3.0 Preview Version1.03)
Does somebody knows where can be found the help file for it?
Preferably in english.
…since i can speak only 3 languages(eng, it, cro).
