Hi Kees,
I attached some images from my current project for you, in case you're interested. It contains nudity. Just so you're warned

It's a baby girl growing into a woman.. It's far from being finnished, but it would not have been possible without your fantastic script. (The character is rigged and skinned, ready to be animated "under" the morph) comments and critics appreciated!
I'm adding changes like "slimmer arms", "softer joints", "developing breasts" etc at a specific age/frame. Then I animate the blend value of those morphs to fade in and out over time.
My problem is this:
When I did the bulging belly for the age of 3 years, I noticed that when I used the same target on the newborn, the vertices on the symmetry line of the belly button move sideways, though I made absolutely shure to offset them in one axis (towards the front) only.
I figured probably morphx2 got confused beacuse of the shape growing underneath, so...
I did a test with a poly sphere, in which I morphed only 1 vertex up along the z axis. When I went back to the editable poly underneath morphx2 and moved the same vertex along the same axis just a bit, the morph did not only add to that, but also affected the other two axis
I really don't get it...
