xGen2UE Script - Export Alembic Hair from Maya xGen to UnrealEngine5

Scripts automates the exporting process of hair created with xGen Maya to UnrelEngine5 (and UE4).

Works with Maya 2022, 2023.

!!! The script will not work if you don't have xGen component in your scene. It doesn't work with grooms created with Interactive Groom Splines.

The xGen2UE Script assigns attributes for alembic file with one click of a button:

- RootUV attribute - Guides Attribute

- Hair width

- Group ID (when you need to separate the groom into groups in UE)

- Automates conversion to Interactive Groom and Generation and reimporting hair curves in the process - combines hair splines (NURBS curves) in case the groom is too heavy (has a loot of hair)

Scripts speeds up the steps described by Epic’s Documentation of how to export xGen hair for UE5 in Alembic format https://docs.unrealengine.com/5.1/en-US/xgen-guidelines-for-hair-creation-in-unreal-engine/

This script was developed with cooperation of Roman Zhuk
