I wanted to morph a dress to match mine Vicky3 breasts and use the cloth room for making the morphs.
I tried the unwelded dress mesh, but the cloth simulation broke the dress.
With the dress welded the result of the simulation was fine, but it is useless as a morph.
I wrote some software that restores the original vertices of a welded mesh but now the problem is that the simulation changes all the dress and I don't want to morph all the dress.
I added to the software an option that only changes the vertices of one group leaving the remaining vertices with the original value. I draw a group that will be the mask of the part morphed.
More or less it worked, but still I have to edit by hand the transitions between the morphed and normal parts.
What I want is even more complicated, I want to select a part of the figure, the selction can be a fragment of a body part or an union of fragments of body parts, with the grouping tool I select an area of the figure that I want.
Then I export this area and the morph it, I don't want to work with the whole mesh, only with the part that want to morph. If I want to make a morph for breast I don't want that the mesh to be morphed has the back,  parts of arms. I want only the breast!
Once morphed how the Hell I can use it as a morph target?????
I don't know how people solve these problems.

Stupidity also evolves!
