Map chunk

Chunks, also know as loading zones are a game mechanic used to load the part of the game word. Chunk are 150x150 square large, there is in total 3347 chunk in the game world without the instanced zone).

NXT and render distance
NXT handle loading square differently from the java client were it only load the chunk the player is currently,it load several more chunks instead but only load the game world, Npcs,interactable scenery configuration are loaded only within the 150x150 chunk the player is currently on, hence why NXT take significantly longer to load locations than the java client.

Instanced areas
The instanced area are area where you are sperated from the main game world, when one enter it, the server duplicate one or multiple chunks and put it in this area wich consist of instanced void that count 73 chunk per server. Instanced area are used for activities such as bossing and sometimes quest specific areas.
