Metahuman Export - UVW's are broken

When exporting the Metahuman FaceMesh, the UVW’s are broken.
I would like to paint my own Texture map, with makeup, etc. but after

Migrate–>Export–> FBX

The UVW’s are destroyed.

  1. What am I missing here?
  2. How can I export the Metahuman FaceMesh with the correct UVW’s?
