Figured it out:
- add Empty >> [something] to your mesh (I used single arrows so you can see socket orientation)
- added empty object has to be named beginning with “Socket_”
- you can add and export them as static or skeletal mesh
- sockets do not have to be parented to mesh in Blender
Below is a single socket at the center of a mesh with export settings. It seems preferable to have your sockets in the Blender source? If you ever have to update the mesh you would lose your sockets added in Unreal editor. (or is there some way around that?)
