Alembic file from 3dsmax to Unreal loses textures

I am exporting an alembic file from 3dsmax to Unreal. I am toggling UV Write in 3dsmax and keeping flattening tracks off in Unreal when importing. I am still losing textures of my alembic file and they are not showing in my slots either.

I am curious how I can export a face set from 3ds max or if I am missing a setting when importing into unreal. Any help would be appreciated!

Thank you,
