Help = Joints twisted when importing animation into Unity

Hello ! I have an issue while exporting an animation from Maya to Unity. Other animations seem fine, however, the run animation has one of the bones -= that looks good in Maya =- reversed in Unity.



I followed the advice found here : https://forum.unity.com/threads/joint-rotation-error-imported-animation.425825/
however this, still does not fix the problem

My export settings from Maya :
- curves are Linear
- 30 frames per second
- no compression and resampling

The import settings for Unity:
- humanoid
- no compression and resampling

I tried fixing the joints manually in the rig configuration in Unity, unfortunately, that didn't fix it.

If I export/import the same animation TOGETHER with the model attached to it, it works flawlessly. The only problem is that I'd like to export the animation without the model attached - so I can have it separately.

Is there anyway to fix the joint problem?

 

I'm having the same problem. Did anyone find the solution?
