I would like to know if it is allowed to take screenshots from scenes made in Unreal Engine and use them to sell Twitch overlays or wallpapers (printable, digital). For Twitch, this would mainly be screens that are shown, for example, when the stream starts, ends or pauses and in the background for the overlay with chat, gamecam and webcam or for overlay customization.
Am I allowed to use such screenshots and are there any license conditions?
Best regards
