Animation don't execute when exporting to Unity

HI!
My animations aren’t working in Unity when I export them from the NLA Editor. I’m trying to export the animations one-by-one, in different files. I have watched many tutorials and used every combination possible in the .fbx exporter in the ‘Bake Animation section’. The animations run when imported to Unity but the rig doesn’t move.
The steps I’m using are:

  • Stack the animations (Actions) in different tracks in NLA Editor.
  • Mute every channel except the one I’m currently exporting.
  • Select .fbx export and eanble ‘Selected Objects’, the ‘armature’ object type and disable ‘All actions’ in ‘Bake Animation’ section.
  • When I import in Unity and check them in the object overview, the frames are there and all but no bone moves.
    One curious fact is: the track which I put all animations together runs very fast. It has like 300 frames and it runs in an instant.
    Also I heard someone saying somewhere that is important to have the animation with only one user, what would be the implication of having more than one? some of my animations have more than one, but idk who are them.
    So, what could be happening? Thanks!
