BiomeTerrain Mod v11.2_3
If Bucyruss happens to come back and wish this to be unlocked, then message me or any other moderator/admin who has the power to do so.
This mod allows alteration to Minecraft’s biome and terrain generation controls/algorithms. This includes, but is not limited to, altering physical terrain generation, biome size/types, ore deposits, surface material generation, block replacement/manipulation, removal/insertion of block (types) and characteristics, custom trees, bug fixes to original Minecraft terrain code, and the introduction of new biome/terrain features.
From the author
First of all, I want to thank everyone for all the support that I have gotten for this mod. There have been tons of great ideas and suggestions; most of which I want to implement. I encourage everyone to keep the ideas coming and I’ll do my best to get them implemented into the game through this mod. You can check my to-do lists at the bottom of this thread to see what has been suggested and that I plan on trying to implement.
Second, while I do enjoy working on this mod, I am only human and have a rather busy personal and professional life. I do my best to keep the updates coming and making sure they work properly, but there will always be periods where updates will be slow and few simply because I don’t have the time to always work on this mod.
I’m really excited that so many people like this mod and feel that it’s made Minecraft even more fun to play. I hope I can keep improving this mod to keep making Minecraft even more fun and exciting to play. Enjoy
Disclaimer: Read the entire post before using this mod, especially if you have never used it before or if you are updating from pre-v10.0. Always be sure to create backups of your world(s) if you do not want to risk losing them or have them unintentionally modified by accident.
Important! This mod is not intended for the browser version of the game.
BiomeTerrain Mod works the same way as Risugami’s and 303’s mod loaders. All class files that begin with BiomeTerrain_ are option files. Add/Use the ones that you want.
Single Player Windows:
1) Download the single player version of this mod. 2) Open/Extract the mod’s .rar file with WinRAR. 3) Browse/Open you appdata folder (Go to Start -> Run, and type in %appdata%). 4) Browse to .minecraft/bin. 5) Open up minecraft.jar with WinRAR. 6) Drag and drop the necessary/desired* files into the jar from the mod files. 7) Delete the META-INF folder in the jar. 8) Close WinRAR. 9) Run Minecraft. *File beginning with "BiomeTerrain_" are optional and may be added/removed as you want as they all function independently of one another. The one exception is that if you use the TreeMod you will have to includes the Trees folder as well as the TreeGenerator, Shrub, Tumbleweed classes as well (until I fix their inclusion).
Single Player Mac:
See this guide.
1) Place the SMP mod jar in the same folder as minecraft_server.jar. 2) Run the minecraft server with the following command line: java -Xmx1024M -Xms1024M -cp BiomeTerrainMod_SMP_v11_2.jar;minecraft_server.jar net.minecraft.server.MinecraftServerImportant! If you are using linux (or mac?) then replace the ";" with ":"
Supported mod plugins
Using the mod
1) You can either download the BiomeTerrainModSettings.ini file or let the mod generate a default one when you create a new world. If you let the mod generate a settings file, then it will contain settings for only the mods that you have loaded. 2) If you download the settings file, then you need to place it in your minecraft folder where your options.txt (ops.txt for SMP) file is located. 3) Open BiomeTerrainModSettings.ini and change the values for settings that you want to alter in the game. 4) When you create a new world, the mod will make a copy of BiomeTerrainModSettings.ini and place it in the world’s save folder. Edit this copy if you want to alter your world after creation.

BiomeTerrain Worlds and Settings
There is a thread that has been started of people posting screenshots of their world(s) and the settings used to create them. I would suggest going here to share settings for different worlds. Here is the link to it.
You can also check out this thread that has really good explanations of the various terrain settings and how to generate different types of biomes and terrains.
All Biome Settings
Modifies the size of biomes. Larger values will generate larger biomes and smaller values will generate smaller biomes. This settings affects the average dimension of biomes on a linear scale, so every doubling of this value will quadruple the area of biomes.
Sets the minimum and maximum moisture of the world.
Sets the minimum and maximum temperature of the world.
Setting this value to a larger number will make snow and/or ice more common and a smaller number will make snow and/or ice less common. Values should be between -1 and 1.
Swamp Biome Settings
Places a strip of mud or clay (size is dependent on the swampSize setting below) around the edge and below surface water. This will only occur in swampland biomes. Thw muddySwamp setting takes priority over the claySwamps setting.
Adjusts how many blocks mud/clay extends from the edge of water for when either the muddySwamps or claySwamps options are turned on.
Desert Biome Settings
Will remove all water from desert and ice desert biomes.
Will remove all dirt from the surface of deserts. This setting was introduced because changing some terrain generation settings will cause dirt to erroneously appear on the surface of desert biomes.
Will turn on the ability to let dirt appear on the surface. This setting occurs after removeSurfaceDirtFromDesert so turning both on will cause dirt to appear in your desert biomes.
Sets the frequency at which dirt will appear in the desert. The setting corresponds to the average number of chunks before a dirt block will appear. Example: setting desertDirtFrequency:100 means that, on average, you will encounter one dirt block every 100 chunks in the game.
This controls the odds that a given chunk will host a single cave and/or the start of a cave system.
The number of times the cave generation algorithm will attempt to create single caves and cave systems in the given chunk. This value is larger because the likelihood for the cave generation algorithm to bailout is fairly high and it is used in a randomizer that trends towards lower random numbers. With an input of 40 (default) the randomizer will result in an average random result of 5 to 6. This can be turned off by setting the "even cave distribution" setting (below) to true.
Setting this to true will turn off the randomizer for cave frequency (above). Do note that if you turn this on you will probably want to adjust the cave frequency down to avoid long load times at world creation.
Sets the minimum and maximum altitudes at which caves will be generated. These values are used in a randomizer that trends towards lower numbers so that caves become more frequent the closer you get to the bottom of the map. Setting even cave distribution (above) to true will turn off this randomizer and use a flat random number generator that will create an even density of caves at all altitudes.
The odds that the cave generation algorithm will generate a single cavern without an accompanying cave system. Note that whenever the algorithm generates an individual cave it will also attempt to generate a pocket of cave systems in the vicinity (no guarantee of connection or that the cave system will actually be created).
The number of times the algorithm will attempt to start a cave system in a given chunk per cycle of the cave generation algorithm (see cave frequency setting above). Note that setting this value too high with an accompanying high cave frequency value can cause extremely long world generation time.
This can be set to create an additional chance that a cave system pocket (a higher than normal density of cave systems) being started in a given chunk. Normally, a cave pocket will only be attempted if an individual cave is generated, but this will allow more cave pockets to be generated in addition to the individual cave trigger.
The minimum and maximum size that a cave system pocket can be. This modifies/overrides the cave system frequency setting (above) when triggered.
Sets the creation variables for dungeons (See explanation of material spawning variables near bottom)
Lava Pool Settings
Sets the minimum and maximum levels at which lava pools can form in caves.
Cloud Mod (SSP only)
Adjusts the altitude at which 2D clouds occur. I never saw these in the game, but they are in the class so I went ahead and added the option to change their altitude just in case.
Adjusts the altitude at which 3D clouds occur.
Adjusts the thickness of 3D clouds.
Above Ground Settings
These settings adjust the creation variables for above ground items. To save on space I just posted a generic representation of the settings for this section.
Above/Below Ground Settings
Changes the water source spawning algorithm to a flat distribution. Normally, water sources are distributed with a higher frequency toward the bottom of the map.
Sets the creation variables for water sources (See explanation of material spawning variables near bottom)
Changes the lava source spawning algorithm to a flat distribution. Normally, lava sources are distributed with a much higher frequency toward the bottom of the map.
Sets the creation variables for lava sources (See explanation of material spawning variables near bottom)
Below Ground Settings
These settings adjust the creation variables for underground items. To save on space I just posted a generic representation of the settings for this section.

Sets the water level of the world.
If this value is greater than 0, then it will affect how much, on average, the terrain will rise before leveling off when it begins to increase in elevation. If the value is less than 0, then it will cause the terrain to either increase to a lower height before leveling out or decrease in height if the value is a large enough negative.
If this value is greater than 0, then it will affect how much, on average, the terrain (usually at the bottom of the ocean) will fall before leveling off when it begins to decrease in elevation. If the value is less than 0, then it will cause the terrain to either fall to a lesser depth before leveling out or increase in height if the value is a large enough negative.
Can increase (values greater than 0) or decrease (values less than 0) how much the landscape is fractured horizontally. If you want to use settings from BiomeTerrain Mod v9.1 or earlier, then you will need to do a conversion (See v9.1 and earlier to v10.0 and greater conversion section near bottom).
Can increase (values greater than 0) or decrease (values less than 0) how much the landscape is fractured vertically. Positive values will lead to large cliffs/overhangs, floating islands, and/or a cavern world depending on other settings. If you want to use settings from BiomeTerrain Mod v9.1 or earlier, then you will need to do a conversion (See v9.1 and earlier to v10.0 and greater conversion section near bottom).
Hard to explain, but think of these as terrain chaos settings. The larger the values the more chaotic/volatile landscape generation becomes. Setting the values to negative will have the opposite effect and make landscape generation calmer/gentler. If you want to use settings from BiomeTerrain Mod v9.1 or earlier, then you will need to do a conversion (See v9.1 and earlier to v10.0 and greater conversion section near bottom).
Adjust the weight of the corresponding volatility settings. This allows you to change how prevalent you want either of the volatility settings to be in the terrain. Values should be between 0 and 1 and sum to some number equal to or less than 1. An example would be to set volatility1 to something high and volatility2 to some negative number. Then adjust volatilityWeight1 to a small number (say 0.1) and volatilityWeight2 to a larger number (0.85). This should result is mostly calm/flat landscape with the occasional chunk of terrain floating or jutting into the air.
Removes the bedrock form the bottom of the map.
Turns the bedrock layer into a single, flat layer one block thick.
Turns all bedrock into Obsidian
Replace Block Mod
Attempts to replace all surface stone with its nearest non-stone neighbor block type (dirt, grass, sand, gravel, or clay). If it cannot find a suitable neighbor block to duplicate, then it will default to sand in Desert biome types and Grass in all others.
This is experimental and not completed yet, but it aims to be a universal, real-time block replacement option where you can type the above format, substituting
(You can type out as many of these as you want in the settings file. The list of block names can be found here)
Enabled the use of custom, biome specific trees in place of the standard Minecraft trees.
Sets the global, starting tree density for all biomes. Increasing the value increases the density of trees in all biomes.
Sets the tree density in each biome individually. Large negative values are used to prevent trees from spawning at all.
These settings adjust the creation variables for cacti. See the settings file for all settings and see the explanation of material spawning variables near the bottom for more detail on what rarity, frequency, size, and min/max altitudes do.
Underground Lake Mod
Underground Lake Settings
Enables underground lakes.
Allows underground lakes to spawn in the air.
These settings adjust the creation variables for underground lakes. See the settings file for all settings and see the explanation of material spawning variables near the bottom for more detail on what rarity, frequency, size, and min/max altitudes do.

-Lit underground caverns (using lightstone) with grass
New Features to Investigate
-Modify height limit (this is a tough one and may never get done)
-Investigate better floating islands (Worked on it and implemented the fractured variables, but not sure if that gets us there). Probably need to modify the perlin noise algorithm Notch uses.
-Investigate the lower levels of the terrain algorithm for better settings placements.
-Ability to update existing chunks with new settings.
-Real-time water level changing.
-Generating rivers (and erosion)
-Look into adding settings to vary biome size by biome type.
-Enable terraforming in Hell.

Explanation of material spawning variables
The number of times, per chunk, that the game will try to make a deposit.
The odds (out of 100) that the game will actually make a deposit.
The size variable for the deposit.
The minimum altitude at which deposits will occur.
The maximum altitude at which deposits will occur.
Setting conversions from v9.1 and earlier to v10.0 and later
If the value is 1 or higher, subtract 1.
If the value is between 0 and 1 then divide -1 by the value and add 1.
n = v9.1 value if (n >= 1) n = n - 1 if (n > 0 && n < 1) n = -1/n + 1
I believe you only have to adjust this for values greater than 0. Any values of 1 or greater were reduced down to 0.999 in v9.1 and earlier.
If the value is greater than 0 and less than 1, then subtract the value from 1 and take the inverse.
n = v9.1 value if (n > 0 && n < 1) n = 1/(1-n)
If you have questions about these conversions, then please let me know
