make human is a stanalone professional human model generating software. it is making slow but steady advancement. its still is in alpha stage but here is a the surprise, it now sport hair right
out of the box.
that's not all, there is new feature for blender.
this is right out of horses mouth "This is an experiment (a prototype in Blender) of a new feature we are developing in our makehuman software. It's a new, original next-gen tool, that automatically models the most probable realistic head. So the user needs just a few clicks to roughly set the most important facial features, and makehuman will do the rest of the work :-)
Actually we have a limited DB at the moment, so the results are still limited."
