[UE5] Import error of static Mesh (.fbx) created by Maya

Hi all,
test_hse|690x388
I have created a fbx model from Maya 2022. Unfortunately it can’t be imported to UE5, showing this message:
Failed to import ‘(file location/file name.fbx)’. Failed to create asset ‘(file location)’.
Please see Output Log for details.

I compared this fbx file with the successfully imported fbx models, the difference are:

  1. Part of the failed-to-import model was created with “mirror” feature.
  2. After the model has been “broken down” into pieces with the “Separate” feature, all pieces can be imported to UE5, however, the combined model isn’t accepted.
  3. In Maya, the failed-to-import model was combined into one piece and the history was deleted.
  4. When I save the model as fbx, I have checked “smoothing groups”, I have also referenced to other comments to save the file in a location with shorter name, for example, on the desktop instead of a folder in another folder… still not working.
  5. As I combined only part of the models for saving, the non-mirrored elements can be imported to UE5.

Would be great if someone can advise how to fix this problem, in terms of:

  1. The Dos and Donts during the saving process
  2. Is there are quick way to
    !
    put the imported pieces together in UE5?

Thank you!
