As I mentioned in my previous reply, and after testing this myself using the Metahuman FaceMesh and the Face_Archetype mesh, this seems to be a bug. Since I don’t have a custom version of the Face_Archetype mesh to test, everything works fine for me when switching between the two meshes. But in your case, since the morph targets work with your HumanMax01 character in the Mesh tab, but do NOT work when you are in the Skeleton tab, and both skeletal meshes are using the SAME Face_Archetype_Skeleton, it’s probably just a bug, and it shouldn’t affect your animation of the character using the techniques shown in these videos: Metahuman facemesh morph target preview not working? - #4 by Dig_Squid
