Uefy 2.0 (Pro Edition) make Blender's rigify rigs compatible with UE5, also has a FREE version

Hi again,

Another question. What is the workflow to use Mannequin metarig, because I’m testing without success, and what is the difference between rigify. I really want to use UEFY, but still problems occurs after retargeting in Unreal. I followed tutorial, but nothing. Always something is off. NO luck exporting it without some issue. Can You please help? This is very important to Me.
