fClone is a new facial motion-capture software that works via a webcam, and can output to Poser’s .pz2 format for use in Poser and DAZ Studio. It’s a little fresh in terms of its versioning, but it’s now in a 1.05 bugfix version.
There’s a free trial available, then it’s $199 for the Standard version, or $50 if you just want to ‘rent’ it for a month of gurning and grinning production work. I’m guessing that $199 price is probably about on a par with iClone’s more mature desktop mo-cap offerings, though I haven’t looked at those or their pricing for a while.
As far as I can tell, the software has nothing to do with iClone or Reallusion, despite the similar name.
