Hello folks.
I’ve been playing many MMORPG’s, completely created in the UE and I’m wondering how the producers where able to create such a huge world while the Unreal Engine is not that big for such a huge map to be able to create.
I’m talking about games like Blade & Soul for example which map is really big and I can’t imagine they built it up just in only single map. Did they build a new instance for any area or something simular? I’m pretty new to the Unreal Engine so would be appreciated to teach or explain gently 
Thank you very much.
Best regards,
Tomas
