This definitely comes from the conversion of the mesh from child to Genesis, and there isn’t much you can do about it at the moment to get a better conversion. The Projection Templates can help with the weightmaps, but I don’t think they are going to cause the refit from the original kids shape to Genesis to improve.
There is an option, though, to help clean it up a little bit. I know you probably don’t want to jump through the hoops, but if you are adventurous I would recommend doing the following:
- After conversion, select the dress and apply the Smoothing modifier (Edit -> Figure -> Geometry -> Apply Smoothing Modifier)
- In Parameters Tab, go to the General -> Mesh Smoothing group. This is where you will find options for smoothing out the mesh.
- Make sure hidden properties are visible (Enable “Show Hidden Properties” in the Parameters Tab options)
- Change your smoothing type from Base Shape Matching to Generic
- Set the smoothing iterations to a number that is high enough to fix the middle of the dress but not so high it smooths out all the details or messes up other parts of the dress. Hopefully it did fix it up a bit…
At this point, if you are happy with how the dress looks, I recommend you export that fixed dress out as an OBJ, import it and use the Transfer Utility to transfer morphs and rigging from the other dress to the new fixed mesh. I wont’ bother explaining how to do that until I find out if everything else worked for you.
