Importing problems

  1. Try to export your file with the 2013 and 2014 version of fbx (the 2014 wont work correctly, but probably it will somehow solve the problem)
  2. So you already flipped the normals?
  3. Could you probably post your step by step exporting process?
  4. Import the obj file that you have sent to your friend into maya and without doing anything with the mesh, just export and import it into the UE4
