Thanks for the feedback/ideas.  I was wondering if there was a way to morph along a path but I guess not based on your eyebrow example.  Tho it makes me curious since Daz characters seem to use morphs for this.   I'll probably use a combination of bones/morphs.

I could really use a tutorial on creating facial expressions...primarily with morphs since that does seem to be the way most users want to see their models.  Are there any 'facial expressions' tutorials around?
