WOW!

Okay, first off RorrKonn... I checked your site and I must say great job on modeling the human heads. I tried some of the freebie modelers available and gave up completely. Modelling just aint my bag :P

And so after reading through this whole thread, I've come to the conclusion that your biggest problem here is.... you've got too much going on at once! I mean, you started off bouncing between C4D, Poser5, Zbrush and Silo... only to end up building a HyperNurb(?) V4 three weeks later. Again, WOW! You've definitely got WAY too much on your plate right now!

The best advice that I can give you (as a non-modeller) is to back up and try to pick just ONE application to work with. After all, you're only human (right?) and it's a known fact that the human body can't physically go in four directions at once... which is exactly what you seem to be attempting here. Granted, a lot of people here use more than one program to create their products and such but, they generally use only one little part of each app to get the job done.
In your case, all you seem to want here is to make some custom morphs for V4. No problem! Poser can do that, especially with magnets (like Angelouscuitry said earlier).

Now, the whole key to Posers magnets is to take things one step at a time! At first, load up a primitive prop (sphere or box) and apply a magnet to it. Experiment and familiarize yourself with the magnet and it's zone. See how they work separately and together. Play around with scaling and xyz coords on both. You'll see real quick just how powerful these magnets are!
After that, go tutorial hunting for some more magnet info (DrGeep is a great place to start). It's only after you're comfortable with Poser's magnets that you should even try tackling V4 with em! Trust me, with you're modelling abilities, learning magnets should be a fairly easy and quick process for you.

I know I just wrote a lot of pep-talk nonsense but, then again I done have any REAL technical jargon for ya! Hopefully my simple advice will help you anyway. If not, then carry on with what you're doing and good luck! I'm looking forward to seeing what you've got in store for us!
