Rotation missing from animation

Hello!

Another TA and I have been trying to fix a problem we have come across, which is that rotation data in the spine of a skeleton have gone missing inside of Unreal. The rest of the animation imports just fine, like all of the rest that share the same skeleton but the rotation in the spine is completely gone, I need to mention that the rotation of the spine in the animation may be small, just below 0.6 in Z to be precise but it is still significant.

We have tried exporting the animation to unreal in every way we can think of but the results remain the same.
We can’t find any problem with the export tool, the skeleton or the rig inside Maya.

I appreciate any help that you can provide.

Thank you very much

Hi there! Can you share the problem FBX file? I just check some from Mixamo and it is imported rather well.
