I did a quick test with the Hexagon Smooth Brush (see the UV/Paint toolset tab) and for me it did just what was asked - it smoothed the polygons. You can turn M4's head into a nice smooth ball with spiky teeth. The morph load worked fine. I am beginning to like Hexagon.

And to the point of commercial release, I indeed made some difficult JCM's for M4 to turn him into  a L4, but when I asked for feedback on DAZ, the interest appeared low so I skipped the project :)
Making a set of JCM's is a difficult task still, you have to do the ERC manually.

Letterworks pointed out that when doing a clothing morph it is convenient to have both meshes in the deformes at once, and this should also work in Hex, I had posted a tutorial somewhere here in this forum.
