Terralith

Terralith ~ Overworld Evolved is a project made to completely revolutionize the Overworld's generation. Released July 28th of 2021, makes a full use of the new WorldGen tools of this version to create beautiful landscapes with new terrain types, like canyons and amplified terrain, painted over by more than 70 new biomes, inspired by places all around the world or by fantastical fauna, while also enhancing existing biomes and adding new variants to them. The new caves were also enhanced with new cave shapes and about 10 new cave types. Alongside this, new structures and features can be found to assist your exploration. was the second project of Stardust Labs and took an entire year for it's creator, Starmute, to understand and operate the new WorldGen tools that were available for Datapacks in. The version is still available as Terralith Legacy, and the newest version of, which can also be called Terralith 2.0, made use of the additional WorldGen options of  to add new terrain types and rework the caves. All the biomes deemed too dark were scrapped from that version to instead allow more marvelous biomes. Since then, thanks to the more documented updates of the WorldGen tools, snapshots, and experience, all updates for are planned to release on the same day as a new major update of Minecraft.

Biomes
's main focus is terrain, but after adding and overhauling Vanilla terrain with new features and shaping, the next step was to paint that terrain with more than 70 new biomes, each with their own block palette, trees, foliage, colors, features, mobs and structures. Here is a full list of the biomes and changes to Vanilla biomes added by. {| class="wikitable sortable mw-collapsible mw-collapsed" style="width: 50%"

Ores
does not modify the ore distribution in Vanilla biomes, and only raises the appearance of some ores in specific biomes. For example, Emerald peaks appear with more Emerald Ores, Scarlet mountains spawn with more Redstone Ores, and Volcanic crater spawn with more Diamond Ores.

Vanilla biomes changes
Although already overalls the terrain greatly, it also modifies some vanilla biomes slightly to make them more alive and thrive among other similar biomes. The changes may vary from the addition of some blocks or changing the shape of a tree to completely new features and or terrain shapes.

Minor changes
Plain and open biomes got some changes to make them feel more alive. Plains biomes, for example, have more grass and tall grass, with some random but rare patches of coarse dirt. The Vanilla Savanna biome also now has rare stripes of dirt paths going through it, as if wildlife lived there and have left trails behind them. The Cold Ocean biomes now have better icebergs.

Some minor changes to Vanilla biomes include trees. changes trees in Taiga biomes, Swamp biomes, and also in the Dark Forest biome, which now has taller trees, making it easier to navigate, with some glow lichen, making it less dangerous but more mysterious.

Major changes
Despite tweaking some detail in some biomes, adds new shapes into the terrain, but without forgetting the Vanilla biomes.

Cliffs biomes can now generate as beautiful Overhangs, making seasides more imposing, Desert biomes are now made of Dunes, making the landscape realistic and smooth, you can also come across Arches in Mesas and finally, you can sometimes stumble upon Mega caves when mining underground.

Oceans have been overhauled, not with new blocks or biomes, but with deeper and more detailed terrain, making deep end of the ocean look equally frightening as it is beautiful.

Features
brings a lot of changes to Vanilla terrain. Here is a list of all of them.

Mega ravines
Mega ravines are WorldGen features found in and Terralith Legacy. Unlike Vanilla ravines, they extend downward, sometimes reaching the Bedrock. Although excellent for mining, they can be deadly if you happen to fall in one.

Mega geodes
Mega geodes are Worldgen features added by version of. Bigger than classic, Vanilla geodes, those geodes are 2 to 3 times bigger and unlike Vanilla ones, they cannot appear connected to a cave, meaning the only way to find them is through strip-mining.

Andesite boulders
Andesite boulders are WorldGen features added to in version. They indicate Andesite caves underneath the surface, just like Vanilla Azalea trees indicate lush caves.

Granite pillars
Granite pillars are WorldGen features added to in version. Functioning like Azalea trees indicate a Lush cave, they indicate that Granite caves can be found underneath.

Diorite patch
Diorite patches are WorldGen features added to in version. They indicate Diorite caves underneath the surface, just like Vanilla Azalea trees indicate lush caves.

Structures
With the release of and the comeback of Vanilla structures in custom biomes and Custom structures,  decided to make full use of this update to return some structures from  and even add some new ones in it's  version. Here is a list of all of them.

Compatibilities
This community-driven list is here to inform you about the Datapacks and Mods affecting the Overworld that are compatible with. Meaning Mods'/Datapacks' structure/ores/plants/mobs spawn in terrain and biomes from Mods/Datapacks spawn alongside them.

If a Mod or Datapack is not in the list, it is either untested, incompatible, or not a mod that has content linked to biomes from or biomes in general. Some of those Mods or Datapacks might have not been updated to the latest Minecraft or version, but will probably work with it once they are.

Note that Fabric mods will most of the time need Fabric API to work and that for this reason it was not listed as an addon needed. Also note that Quilt is not a perfect replacement for Fabric and that some mods might no work properly with it.

Do not hesitate to update/rectify/add known compatible Mods or Datapacks to the list.
