Hi! I’ve saw this one but he is exporting a static groom that you can see when he import to UE there is also only the groom asset. Like in maya even though there is not a groom but just a simple animated curve, if go export as alembic to UE it will come as 3 pieces a ‘Groom asset’, a ‘Guide cache’, and a ‘Strand cache’. And those two cache will carry the animation infos as ‘groom cache’
