1. How would one go about gaining access and a license to use images from a character creator as simple as that of Black Desert or City of Heroes?

Reallusion, Mixamo, MakeHuman. Are not really my cup of tea. I want something simple with limitless character creation potential.

Not to be used in a video game, rather for taking still shots to be sold as part of board/card games, cover art, etc.

2. The next question is, is it possible to get this in the context of a 3d world?

Ideally licensing through NCSoft or Pearl Abyss would be the way to go. That said, getting ahold of either company is near impossible.
