Examples
Looking for guidance on how to achieve a certain look, or hunting for inspiration? Check out these common Terrain Control use cases. Mysource has made some other examples over here.
### One Giant Biome Back to top
Want an all-desert world? It's easier than you might think!
The setting to pay attention to here is NormalBiomes inside the WorldConfig.ini—simply remove all other biomes from the list and leave only the one you'd like. Depending on the biome you use, you might want to make the world one huge endless continent by setting LandRarity:100 and get rid of all ice with IceRarity:1.
NormalBiomes:Desert
LandRarity:100
IceRarity:1
### Ocean world Back to top
The easiest way to create an ocean world is by setting both LandRarity and IceRarity to 1 in the WorldConfig.ini. Your world is now one large ocean, there are no continents anymore. You could also set the water level (WaterLevelMax) to something higher to get more water. You can also lower the ocean floor by setting BiomeHeight in the OceanBiomeConfig.ini to something lower (but avoid -2.0, because that value is bugged!).
### Skylands Back to top
Skylands are created using the CustomHeightControl variable in the BiomeConfig files. You can find a detailed example here.
### Vanilla world Back to top
Sometimes you just need to change one thing of the generator (add a BO2 for example), without changing it further from vanilla, for example because you want to avoid borders with your vanilla world. This isn't done by setting BiomeMode and TerrainMode (WorldConfig) (ModeBiome and ModeTerrain in Terrain Control 2.2.5 and older) to Default: Terrain Control will completely ignore all generation settings.
Instead, you should set BiomeMode to Default and TerrainMode to Normal. If you don't change the BiomeConfigs the terrain settings will already look almost like vanilla. Biome placement is even with the default settings different from vanilla, but because BiomeMode is set to Default the terrain generator will use the biomes of vanilla.
There is just one little difference that remains: Terrain Control's default water level is one block higher.
Set WaterLevelMax (WorldConfig) to 63 and you have a vanilla world.
Here, we'll give snowy mountains a relatively higher density of diamond ore. Open the Ice MountainsBiomeConfig.ini file. We'll adjust a few numbers in the resource queue for this one. Ores are distributed using the Ore(Block,Size,Frequency,Rarity,MinAltitude,MaxAltitude,BlockSource[,BlockSource...]) directive, where:
- 
Blockis the block ID (or name) to distribute - 
Sizeis the average size, in blocks, of each generated ore vein - 
Frequencyis the number of veins to generate per chunk - 
Rarityis the percentage chance of each vein actually being placed - 
MinAltitudeandMaxAltitudeare the vertical bounds of the ore distribution - 
BlockSourceis one or more block IDs (or names) which the ore is allowed to replace 
Thus, in Ice MountainsBiomeConfig.ini, we have:
Ore(DIAMOND_ORE,11,7,85,0,32,STONE)
