Another forum might be best. Underage persons can see violence, there is no law against it, but it is technically unlawful for minors to see sexually explicit material in the States. It’s seldom enforced, but I don’t see Epic doing anything but washing their hands of it, to be honest. I can’t speak on their behalf, but my best guess is that they’d say something like, “We’re stoked you’re using the engine, but we’d prefer to showcase other material.”
