I remember it being announced at SOU and it looks like all the other plugins announced for Maya, Houdini and Marvelous have all been released but the Blender one hasn’t. Is the Metahuman for Blender plugin still coming?
None from Epic games as far as I know. But I just created my own Blender add-on to do just this.
Full Metahuman support without leaving Blender, from importing DNA files, sculpting meshes, editing base mesh, skeleton, facial expressions, BRF solver etc.
If you want to check it out I have some more information, including a free version here:
