Failed to import Blender Hair to Unreal Engine

Support Basics & Interface
1

I created a particle hair system:

blenderHair
blenderHair746×786 63.9 KB

and when I exported it as an Alembic file and tried to import it in Unreal Engine, I get this error:

Alembic_Problem
Alembic_Problem1157×826 71.5 KB

I also find it strange that the alembic file only has 1 kb:
1kb

Have anyone else ran across this problem? :frowning:

This is how I exported the hair from Blender:
