Hey! I came across your post and would love to help create both custom hair and fantasy clothing for Seiro. I can make sure everything fits your MetaHuman properly and is fully rigged and animation-ready for Unreal Engine 5.8. I'd be happy to share some relevant examples of my work as well.
Could you share the hair and outfit references you have in mind?
