I would check the Centaur and Stuff thread over at DAZ.  There used to be a nice tutorial by Crescent on popping on a different head, but the site has gone away, and the WayBack macnine doesn't seem to have the pictures...

The Wisdom of bagginsbill:

"Oh - the manual says that? I have never read the manual - this must be why."
“I could buy better software, but then I'd have to be an artist and what's the point of that?"
"The [R'osity Forum Search] 'Default' label should actually say 'Don't Find What I'm Looking For'".
