Texturing a metahuman character

While the Metahuman characters for Unreal Engine are really gorgeous out of the box, I was wondering whether it is possible to add some custom textures to the face. It would be great to add some scars and face paint, or transform the character into an alien-like humanoid. The workflow for doing that is actually quite simple. :-)
