ML Deformer problem with FBX animation and Alembic synchronization for training.

A little update to say that I redid all of my test under the 5.2 release and nothing have change.
Plus I now have a proof that because of that, it generate wrong deformation on my mesh.

I have zero idea how this is suppose to work since it can’t synchronize my FBX and my ABC. I really need help on this please.

Thanks a lot.
