Python script to bake Segment Scale Compensate result?

[matveev7ly7nikita172]

I have already make many animations using Segment Scale Compensate, but I need to import these animations to Unity, unfortunately, while SSC is enabled, animations won't work normal in Unity.
Since I have many animations, I don't want to modify these manually, so I need a script to turn off SSC and keep animation unchanged.
Does anyone know how to do that?

Example fbx file in attachment

Bip001_Spine2_M's scale is (1, 2, 2)

child bone Bip001_Clavicle_L turn off SSC, so it got a bad scale
child bone Bip001_Clavicle_R turn on SSC, so it got a good scale, I will to keep this result after turn off SSC.
I try to lower Bip001_Clavicle_R's scale, but since its scale axis is diffrent to parent's scale axis, so that's not going to work.
I think it need some matrix operation, but I am really a noob at matrix math, I spent many hours and still got nothing, really need help.
Thanks!
