Meta Human Character Customization

So I want to implement a character customization/creator and I thought it would be cool to use meta humans for that. Does anybody know how to do this? Im relatively new to unreal an especially to Character customization…

Metahumans are cool to use, but hell to modify…
Especially if you don’t want to break anything else along the way.

I’m not a professional modeler, but I imagine you’ll need to add a lot of morph targets to the model to customize the character’s features, similar to how facial animation works.

Do you have an advice for something else I could use?

Something like this
