Customizing metahumans

Hello!
I recently started to play around with metahumans, and clearly, at this point, the focus/selling point is the face creator.
I’m asking if it is okay to change the clothing in Blender for example, and still use it in a game that I’m making on the unreal engine?

Or is it not acceptable to customize your metahumans in “third-party” software?

Thanks,
Roope-Elias

Yes you can modify Metahuman assets in Blender provided that those assets are finally used in a UE product. Here’s the applicable EULA language -
