Thanks for your reply!

In the past I've tried to use Bryce to make a height-map 3D face from a 2D photo but its never been nearly smooth enough to be useable.
I've done some research on 3D programs but can't seem to find one that would do this. Iv'e found plenty of terrgen-type programs that use heigth maps to make 3D terrain but not one that seems like it would make a decent-looking face.
I don't want to be a pain but can you reccomend one (if you know of any) or point me to a tutorial?
