UE4 has UMG, which is much easier to use for UI creation than Flash&Scaleform duo.
It isnt capable of making complex animations like a cartoon though, so you may want to make the animation in Flash, render it as a movie and then use that movie as the intro of your game.
UDK 3 support Adobe Flash Player.
UDK 4 doesn’t support Adobe Flash Player.
how can I solve this problem?
Does any substitute exist?
i want to add some animations in UE4 , such as a lot of stories.
those stories i want to set before my game start.
