I have a character which had xgen eyebrows and eyelashes. The mesh has about 250 blendshapes for facial animation. I wanted to transfer this to UE4 and I did that by transferring the mesh with blendshapes to UE4. And the xgen hair as alembic. Turns out UE4 doesn't support alembic hair animation (or simulation) if the underlying mesh moves via morphers.
Great, so I had an idea, what if I convert all those xgen hairs to mesh strands and export them all as morphers. I convert the xgen into mesh and used wrap deformer to move them in the scene using the already applied blendshapes. Unfortunately you cannot export this using fbx and I am stuck.
I could use help this,
How could I possibly move facial hairs like brows that are attached to a face with blendshapes and not bones, inside of unreal engine? The hairs are not part of the blendshapes.
