How Minecraft’s Customize World Settings Work.
If you’ve played a ton of vanilla Minecraft and are looking for something a little different, you might want to try making your own world. These are Minecraft maps that you create by changing world generation settings, resulting in exciting and unique configurations that can lead to hours of fun.
In this article, we’ll show you how you can create your own world in Minecraft, and then discuss what each setting does.
How to Create a Customized Minecraft World
The custom world, now called “Old Custom World”, refers to a custom world type that allows users to replace the default world landscape with features of their choice.
Mojang introduced the old custom maps in version 1.8. The ability to create old custom maps existed prior to the 18w05a version 1.16 snapshot. Subsequently, it was replaced by the creation of custom maps by changing the code of the corresponding .JSON files.
To create an old customized map, you first need to revert to the 18w05a snapshot. To do this in Minecraft Java Edition:
Open the Minecraft launcher. Select “Settings”.
Make sure the Snapshots checkbox is checked, then select New Install.
From the drop-down list under Version, select snapshot 18w05a.
Name your installation and click Create.
Hover your mouse over the installation you just created and select Play.
The launcher will display a warning message. If you accept the terms, select “Play” to start the game.
Now that version 18w05a is running, creating your own world is easy. For this:
Select Single Player.
Select Create New World.
2-Select “Advanced World Options”…
Find the button that says “World Type: Default” and press it until “World Type: Custom” appears. Then select Customize.
Customized World Settings
There are four pages of settings, and we’ll describe what each setting does in the section below.
Page 1: Basic Settings
Page 1 covers all the basic settings that affect the creation of structures and the formation of the terrain. There are a total of 18 customization options in this section. These include:
Sea Level: Changes the surface level (in blocks) of all rivers and oceans. The default value is 63 and can be set from 1 to 255. The higher the number, the less land will be above the water and vice versa. Caves: affects the creation of caves. The default option is “Yes”. Setting this option to “No” will cause caves to not form. Fortresses: affects the creation of strongholds. There are typically 128 strongholds, each with an end portal. If this option is set to No, strongholds will not be generated and there will be no portals. Villages: Affects whether villages are generated or not. Villages are required for villagers, so setting this to “None” will mean that villagers can only be obtained by curing zombie villagers (so mobs should be able to spawn).
affects the creation of mines. Setting this option to “None” will not result in any significant changes to the gameplay. Temples: affects the creation of temples. Disabling this setting will prevent the creation of Jungle Temples, Desert Temples, Witch Huts, and Igloos. Ocean Monuments: Affects the creation of ocean monuments. They only form in deep ocean biomes, so if they are not in the world, they will not form. Disabling them will not greatly affect the gameplay. Gullies: If you set this option to No, gullies will not form. They only spawn underground. Dungeons: Affects the creation of dungeons. Remember that dungeons are only generated if they are connected to an opening. If you turn off caves, fortresses, ravines and underground lakes, then no dungeons will form. Dungeon Counter: Options can be set from 1 to 100, with a default value of 7. This refers to how many times the game will try to create a dungeon in each fragment during map creation. The higher the value, the more likely the dungeons will be available. Water Lakes: If set to No, water lakes will not be created.
Water Lake Rarity:
Affects the chance of Water Lakes spawning. The default value is 4, and the parameters can be set from 1 to 100. The lower the value, the more likely it is that there will be water lakes when the map is created, and vice versa. Lava Lakes: Affects the formation of lava lakes at the surface level. Does not affect lava spawning in caves. Rarity of Lava Lake: Affects the chance of Lava Lakes spawning. You can set the parameters from 1 to 100. The default value is 80. The lower the value, the more likely it is that lava lakes will appear when creating the map and vice versa. Lava Oceans: If this option is set to Yes, all oceans and rivers in the world will be filled with lava instead of water. Biome: In this setting you can list all the biomes you want to see in your Minecraft world. The default value is “All”. The biomes you can choose from include all those available in the overworld, except for the desert M (sunflower plains). The End and the Nether are also inaccessible.
The options for this setting can range from 1 to 8, with a default value of 4. Each number added doubles the size of the biomes, effectively mimicking the Large Biomes setting. River size: The default value is 4, but you can set this parameter in the range from 1 to 5. The larger the value, the larger the river, but the smaller the spawn. A smaller number creates smaller rivers at a much greater frequency. Page 2: Ore Settings
There are 11 sections on page 2, each corresponding to a specific type of ore. The distribution of emeralds and ores in the Nether cannot be changed.
Spawn Size: The maximum number of ores that can spawn in an ore vein, from 1 to 50.Number of spawn attempts: how many times the world generator will try to spawn an ore vein in each chunk. If he tries to place it in an invalid place, the vein will not appear. Min height: 0 to 255, the minimum height at which ore can spawn. Max Height: 0 to 255 is the maximum height at which ore can spawn. Page 3 and 4: Additional settings (sliders or text settings)
Pages 3 and 4 show the same settings but as adjustable sliders or text input. These pages contain 16 settings related to the landscape of the world, and primarily the rules for creating mountains and valleys.
Main noise scale X: parameters from 1 to 5000, default 80.
Higher default makes mountains smoother in the Z direction; lower by default adds gaps in the mountains in the Z direction. Main Noise Scale Y: parameters from 1 to 5000, default 160. Higher defaults make mountains taller and more compact, lower defaults make mountains more rough with protrusions. Main Noise Scale Z: Parameters from 1 to 5000, default 80. Higher default makes mountains smoother in X direction; below adds gaps in the mountains in the X direction by default. X Depth Noise Scale: Options from 1 to 2000, default 200. Creates a sharper change in the X axis.
Z Depth Noise Scale: Options 1 to 2000, Default 200. Creates a sharper change in the Z axis.Noise Depth Index: Options 0.01 to 20, Default 0.5. A higher value means more floating plateaus, and a lower value means more hilly floating islands. Base depth dimension: parameters from 1 to 25, default 8.5. Specifies the base height of the ground, and each point corresponds to 8 blocks. Bedrock still generates below the base level. Coordinate scale: parameters from 1 to 6000, default 684.412. This setting stretches the mountains into the landscape. A value below the default means wider mountains, and a value above the default makes the mountains narrower and steeper. Growth scale: parameters from 1 to 6000, default 684.412. This option stretches the world vertically. Higher values mean higher and steeper flat areas, while lower values round the tops of mountains. Height Stretch: Parameters from 0.01 to 50, default 12. Below the default values, everything is stretched upwards, and at higher values, the world becomes flat.
Upper Limit Scale: Parameters from 1 to 5000, default 512.
The closer the upper limit scale is to the lower limit scale, the harder the terrain. The farther they are from each other, the more holes appear in the area. Lower limit scale: as above. Biome depth weight: parameters from 1 to 20, default 1. Higher values increase the height at which biomes are generated. Biome Depth Offset: Parameters from 0 to 20, default 0. Higher values increase the surface level of the biome, but not the features of the biome (e.g. hills). Biome scale weight: parameters from 1 to 20, default 1. Each increase in the value increases the weight of other biome settings, increasing their effect. Biome Scale Offset: Parameters from 0 to 20, default 0. Higher values stretch certain biome characteristics based on other biome settings.
Note. Some of these settings can significantly increase the time it takes to create a map and may cause the game to crash. If so, allocate more RAM and try our quick fixes to prevent Minecraft from crashing.
Infinite Customization Potential
