Comprehensive Guide:World

Mechanics that change terrain and how players can interact with terrain.

World generation

 * The world is 13000 blocks in radius. Traveling beyond this radius is blocked by an invisible and circular world border. Any attempt to travel beyond will result in being teleported back into the radius at a seemingly unpredictable y-level. If a player tries to cross the world border in a vehicle they will automatically exit the vehicle. Blocks may be placed outside of the world border yet any pearls stored outside the world border will be freed upon server restart.
 * Several non-vanilla biomes have been added. Many of these biomes have altitudes above y128 and sheer cliff faces. Biomes can also contain custom trees which are larger then vanilla. Blaze spawners can be found scattered around many biomes.
 * Large caverns with flat dirt floors generate under many snow biomes.
 * It is not possible to reach the Nether. However Nether biomes containing Nether materials and creatures can be found in oceans throughout the map. Though Nether fortresses will spawn in nether biomes, wither spawning is not restricted to nether fortresses. Water placement allowed in nether biomes.

The End dimension

 * There are only three End portals. A public End portal can be found at °N, °W
 * The End world generation is also custom. Cobwebs and Lava can randomly spawn at the lower levels of the End.

Orebfuscator
{source, config}



Orebfuscator (from ore obfuscator) prevents using X-ray to see blocks a normal player cannot. First, it hides useful blocks as stone when outside an eight block proximity. Second, it causes random blocks to render underground.


 * Hidden blocks that render as stone when viewed from a distance include:
 * chest, ender_chest, trapped_chest and clay, in addition to all types of ores and shulker boxes.


 * Random blocks that render underground in order to obfuscate include:
 * cave_air, cobblestone, mossy_cobblestone, obsidian, stone, TNT, clay and all types of ores

Due to lag, even nearby blocks can sometimes appear as obfuscated. However, Orebfuscator only modifies what the client sees and thus the obfuscated blocks are not actually changed.

Usage

 * Because of the range of the Orebfuscator, it is advisable to dropchest at least 8 blocks below the ground.

Block limits
Limits the amount of lag causing blocks {source, config}

Some blocks are limited on a per chunk basis to reduce lag. Trying to place beyond the limit is not possible.
