The silence from Epic is disappointing, but the conversation was not unproductive. A few possible takeaways:
Copyright ownership questions linger around A.I. generated assets. This issue is particularly acute for market packages that consist of repackaged/unaltered A.I. generated images from generators that sample artwork without the permission of the original author. Likewise, it’s possible that text inputs to generate images don’t meet the threshold to be considered creative input by a human author, although this issue is yet to be tested in courts.
In practice, this muddies a developer’s ability to enforce DCMA requests. It’s possible that third parties may steal certain generated images from your game with no repercussions. Unlike other assets, they won’t need to produce a receipt from Epic Games.
In short, a safe approach might be to limit A.I.-generated artwork to placeholder content.
Without a response from Epic, it’s reasonable to assume that Epic is fine with it.
