[Fixed][Unity 5.6] FBX is missing the arm animations, but it's working in Unity 2018

[manutoo]

Hello,

I have an animation in a .FBX file which produces no animation on the arms in the latest Unity 5.6 version.

When checking the animation, it’s missing the track to animate the arms :

Here is another anim, all identical in its settings & biped setup, which is imported correctly :

I tried to import the 2 anims in Unity 2018.3 and it worked correctly.

On another animation files, it’s the arm twists which don’t work, although they also work in Unity 2018, and the twists work correctly in some other animations in Unity 5.6.

Would anyone have any idea how to make it work in Unity 5.6

I attached the .FBX files if you want to give it a try. [EDIT: deleted as the solution is found]

Note: I tried to export using 2 older versions of the FBX format, for the same result.

Thanks in advance for any tip !

quickly loaded them in 5.65
both of them are fine as generic

when switched to humanoid, the arms are a bit distorted

I’m not an expert but you might try to give the hand and legs a bit of angle so they are not so in a straight line in the T-pose

Thanks for the test !

I tested in another test project in Unity 5.6 and it worked fine. So I deleted the file in my current project, and then re-added it and it worked !

So I guess Unity wrongly cached some stuff… Pfff, I hate computers…
