Using marketplace assets in a Adult content game?

I know it’s okay to use the Unreal Engine itself when creating a game that contains Adult content (nudity, sexual acts, etc.) as long as it’s legal. My question though is are you able to use the marketplace assets as well. I have not been able to find any definitive answer on this. Unity for example says it’s okay to use their engine for an Adult themed game but specifically states no assets from their marketplace is allowed. I’m wondering if Unreal has that same limitations or not?
