[FBX] Separate animations, problem

Anomaex

Good Day, Guyz! Faced a problem, unexpected and unpleasant.

Have a model, now I will take only the skeleton as an example, without any Animations... (with mesh, everything is identical)

Export the skeleton in FBX , export preset "Autodesk Media and Entertaiment", change scale factor to 100, in Centimeters and file version to Binary 2018. (but i tried different, from 2017 to 2020, everything is identical)

After drag-drop import to Godot, and in Import settings set preset as a Single Scene, and Re-Import. Open how New Inherited and see all fine all it's okay, have only skeleton.

Next step the same skeleton, but have baked keyframe, with animation, 24 frame, 30 fps, simple Forward Run

Export with the SAME config how export first skeleton!!! And drag-drop import to Godot, and in Import settings set preset with Separate Animations, Re-Import!! and Godot create anim file with animation for this skeleton.

---

Open this skeleton and check animation, all fine, have run animation

Open First skeleton without animation how New Inherited, click to AnimationPlayer, load animation from second skeleton...

AND our animation is !!! BROKEN !!!, skeleton the SAME , model bone hierarchy the SAME... idk why its happened...

RESULT: YouTube video: https://youtu.be/NFKN831_Aqc

This problem slowed me down a lot, in my project I need to separate animations according to other models, and if there is such a problem, then it is very unpleasant.

Who faced such a problem, how did you solve it?

Test models FBX files attached in zip file.

AFAIK this doesn't work by default, but I haven't got that far in my project (though I do need this functionality as well, since the character file I received from the artist has separate animation FBX files). The way to fix this is animation retargeting, but that is not supported in Godot 3.x and will come I believe with Godot 4.0. There may be a way to hack it with code, but as I said I haven't got that far.
