Reimport FBX Model Doesn't Work

The issue still persists in UE version 4.10.4 but we found a work-around until it is fixed (this information may also help engineers to find the source of the bug).

The work-around is quite simple:

  1. Open the uasset editor.
  2. Scroll down to “Import Settings”.
  3. Expand the “Show Advanced” options.
  4. Disable “Build Adjacency Buffer”.
  5. Save the uasset.
  6. Reimport at will!

This worked out for us but we also found out that everyone working with those assets needed to perform this work-around manipulation otherwise the assets don’t update properly through versioning software (Git, Perforce, etc).
