@Deathrey @Chosker, Just don’t read those posts and don’t reply. You already know what happens in the end.
Back on topic, this feature is currently not supported in UE4 and there’s nothing you can do about it. It requires lots of hard work that has to be done by the engine development team. After Frostbite 3, Cryengine is the second engine to have this feature built in. But if I’ve learned one thing from comparing other engines with UE4 it’s that you shouldn’t expect to have the cool stuff, also at the same low cost in UE4 like other ones. We’re still struggling with performance issues with almost anything related to landscapes (tessellation, performance per layer, grass tool, etc.) it’d be very unrealistic to ask for new landscape specific features while the basics are almost broken and not production ready.
