Well the big question is “how does UE4 manage morph targets” as traditionally to maintain performance the mesh containing the shapes would have to up load each frame of the morph as it’s being rendered. I do know with past engines this is an issue but I don’t know…yet…if UE4 handles the load as an instance copy. (it’s on my list to try). If morphs is instanced then you can have hundreds of characters.
But
The need for digital people (NPC’s) has been around forever and there are already turn key software solutions, Daz Studio being one of them.
For example you can do this.
