"The V4 ++morphs contain well over 200 head morphs to change V4's expressions."

Well, there are maybe 200 DIALS, but not 200 actual morphs.

Several of these new expression morphs are just ERC dials to activate other morphs.
A lot of morphs are also just split into "left" and "right", which is also unecessary, as P6 and P7 can split any morph along the x-axis if you want.

And there are even more ERC dials that again combine these
split morphs to "save" you dial work. 
So instead of a single "smile" morph you can split yourself when necessary, you now have three new dials:
"smile left", "smile right", and a dial to activate both of them simultaneously.
AND a fourth dial to activate "smile" along with several others to make a "happy" face.

Using face files instead would have been a much smarter solution and given a lot more options without adding a gazillion of new dials.

So after close examination, there are only about a dozend genuinely "new" expression morphs in V4's cr2 that were not available for V3.

And while  we can now enjoy such amazing new sculpting morphs like "lacrimal size", a lot of usefull V3 head morphs are missing.

But I'm very sure either DAZ or some independent artist will create an extended face sculpting pack, soon.

For a little extra fee, of course.  :biggrin::rolleyes::biggrin:
