(Maya -> Unreal) Skeletal Mesh normals import as hard

I have a mesh in maya that has soft normals. I bind it to joints and when I import the corresponding fbx into unreal, some of the mesh parts come in with hard normals. I also noticed that the same happens if I lock the normals in maya. I am not sure why some soft normals come through and others don’t. I cmade sure that the faces and uvs are all connected. I also made sure that smoothing groups are exported in the fbx settings.

Thanks in advance!

After much tinkering I was able to find a solution

Duplicate skinned mesh with input graph
Then select original mesh and run following normals procedures
unlock
hard
smooth

Then transfer normals from duplicate to original.
From that point all the normals should stick as expected.
