Blender FBX Import duplicate nodes


I’ve read many many post on this subject, some old, some more recent, but I can’t seem to find an answer to my problem.

Exporting a simple mesh with an armature from blender as a binary .fbx and importing it into unreal works perfectly fine, expect that I get duplicated bones, please see the attached screenshot.

What I’ve tested so far:

  • Checking “Import Meshes in Bone” → does not change anything
  • Playing as much as I can with all blender export settings, nothing matters
  • The only workaround found is to export as an ASCII FBX, this gives me exactly the right number of bones, but the scale is now completely messed up and I would prefer to use binary files.

Any help will be greatly appreciated, thx!
