Marvelous Designer Support

Hi,

I am having a hard time figuring out how to import an alembic animation of a Metahuman from Unreal, that I've Baked in sequence and exported as FBX and recompiled into an Alembic so I can use it into Marvelous. After importing it, it appears that my alembic is on lying on the Z axis. Unreal is based on a different world coordinate as Marvelous, because I can not edit an Alembic or it breaks the animation, what am I supposed to do?
Thanks for your help.
