I have one imported character (from Daz) that is recognized as a CC3+ character with a CC4 Extended expression profile. So far so good. I then modified that character externally, which added vertices, so I had to re-import the new character as a Humanoid.
Even though the head is identical between the two models, nothing I try seems to allow me to transfer the blend shapes from the CC3+ version and the Humanoid version.
Q: Are there any work-arounds or hacks that will facilitate the transfer of morphs between (nearly) identical characters with identical heads?
