[FBX Exporter] "no mapping from Unity" while exporting Skinned mesh with animation

Hi @markvi ,
I'm using 2020.3.15 with FBX Exporter 4.1.1

I have a skinned mesh with many animations. I want to export an fbx file that contains all of them and edit those in an external application.

My settings are as shown:


The animator is on top GameObject (Chal_Rig2). There are multiple Skinned objects under the root object.
When I export I get many
no mapping from Unity "uniPropertyName" to fbx property
warnings. I also get an animation on the root object. No other bones are moving.
I also tried with 1 skinned mesh, results are same.

Are there any requirements regarding "Animator" placement, bone naming or GO Hierarchy while exporting Skinned Meshes?
Is that warning the cause of the problem and can I solve it?

Thanks in advance

 

I also have this problem. Did you find a solution in these months?

 

Same huge problem, a solution please?

 

For me, the problem was that the FBX exporter doesn't work with humanoid animations.
The only solution I've found for exporting .anim files, which are humanoid, into .fbx format, is to use this package:
Animation Converter
I converted them to generic and was then able to export them correctly in .fbx and modify them in Blender.
