Not long ago, Mixamo got Unity to ban a lot of their marketplace sellers for selling Mixamo animations without permission.
And in this case, Epic is actively involved by giving Orca money for participating in the monthly free selection AND ignoring all evidence given to them that Orca has not only stolen animations from Mixamo but other sources as well.
I am sure Tim Sweeney isn’t all too happy that his marketplace team is opening his company to potential legal liability.
