Welcome to Tectonic, a world generation project that aims to transform how terrain is shaped.
Tectonic's supported versions right now are 1.21.1 and 26.1. Other versions will not have issues fixed on them.
Biome Mod Compatibility **Most Biome Mods (BOP, RU, NS, BWG)** Tectonic is compatible with mods that rely on Terrablender or Biolith to add their biomes to worldgen. This includes Biomes O Plenty, Regions Unexplored, Nature's Spirit, and more. **Terralith** Tectonic has a special version with Terralith compatibility. This version is shipped in the mod version of Tectonic, but it is available as a standalone datapack [here](https://modrinth.com/datapack/terratonic). **CliffTree** On 1.20, Tectonic and Clifftree are **not** compatible. On 1.21, Tectonic needs some small tweaks to work with CliffTree. These tweaks are shipped with the mod version of Tectonic, but they are available as a datapack [here](https://modrinth.com/datapack/clifftree-tectonic).The mod version of Tectonic has a config for editing many of the following features. Tectonic v3 has a config screen, making it easier than ever to know what certain fields do and to configure them in-game.
In Tectonic v3, terrain forms into continent-like landmasses. Continents will generate thousands to tens of thousands of blocks wide, tailored to account for the project's massive mountain ranges and new terrain types.
In the oceans between continents you'll find relatively smaller "islands", ranging up to around a thousand blocks across. These islands use vanilla's mountain terrain shaping, now making it possible to find traditional mountain rings.
With Terralith installed, these islands spawn Calderas and Volcanoes!

Oceans are much deeper than they are in vanilla, with deep oceans even extending into the deepslate layer! Deep oceans in particular have more varied terrain, featuring overhangs and valleys.
If the mod version is installed, vanilla Ocean Monuments will generate deeper to compensate for the deeper oceans.
The biggest highlight of Tectonic's terrain is the massive mountain ranges. They can stretch for tens of thousands of blocks, going high enough to approach the build limit!

In mountainous terrain that is too towering to allow regular river generation, terrain gets carved for rivers to continue underground. These link right up to the regular rivers, so there's no interruption in exploring along rivers. These rivers vary vastly in size and shape.
If the mod version is installed, these will have increased glow lichen and rare areas with lanterns!

Very deep underground, you can find a deeper variant of underground rivers with different shaping and lava instead of water.

Some jungles feature massive pillars that can extend upwards of a hundred blocks tall!

Some badlands will generate very large canyons, making them a spectacle to find and travel through.

Most deserts will generate smooth, rolling dunes.

In some areas, towering 2-3 tiered plateaus will generate. These plateaus will sometimes have smoother "ramps" to make exploration in survival more accessible.
Badlands also feature isolated plateaus, not directly bound to nearby rivers.

While plateaus usually elevate plateau biomes, some Cherry Groves and Pale Gardens have the plateaus surround the biome, turning the biome into a valley.

Some forest, jungle and taiga biomes generate very close to sea level and generate frequent ponds and lakes.

Changes
- Reintroduced Neoforge 1.21.11 support.
- Made underground river lanterns a bit more common.
- Fixed the world being flooded with the Mushroom Fields biome when Ocean Offset is set to numbers below -1.
- Datapacks that change the build limit won't also change the generation limit if Tectonic's height limit settings are kept at their default values.

The largest Tectonic update ever is here. A full rewrite, a plethora of new terrain types, and improvements to almost all existing features. This is the Everest update.
Made with love by Apollo. 💜
Config Overhaul
[Mod Only] There is now a config screen for viewing and changing Tectonic options in-game! Every option has an explanatory tooltip and its default value displayed. The tooltips replace the comments in the config file to reduce clutter.
This also comes with 16 new config options. Please see the config screen for more information on these.
Continents and Islands
Terrain in v2 was split roughly 50/50 between land and ocean, with no coherent shape for either. In v3, terrain now forms into more coherent "continents".
Continents will generate thousands to tens of thousands of blocks wide, designed for Tectonic's massive mountain ranges and new terrain types.
In the oceans between continents, you'll find relatively smaller "islands". These range from a few hundred blocks to around a thousand blocks across. These islands use vanilla's mountain terrain shaping, now making it possible to find traditional mountain rings. With Terralith installed, these islands have Volcanoes and Calderas!
[Mod Only] A config option to remove the random normal ice in Frozen Oceans has been added to help with ocean exploration in the new bigger oceans.
Jungle Pillars
Some jungle biomes will generate towering pillars covered in vegetation stretching upwards of a hundred blocks high!
Biome Valleys
Sometimes, you will find cherry groves and pale gardens nested inside of a valley!
Badlands Canyons
Some badlands will feature massive canyons, carved around rivers.
Badlands Buttes
Other badlands will generate isolated plateaus in an otherwise flat, desolate region. These are a perfect place to find red sand, which could be difficult to get in older versions.
Wetlands
Some forests, taigas, and jungles will feature very flat terrain with frequent ponds and small lakes.
Rolling Hills
Some plains, flower forest, and ice spikes will feature very smooth rolling hills.
Chunk Blending
Tectonic v2 worlds will blend into Tectonic v3 worlds (somewhat) smoothly! There will be 1-5 block seams at the border between old and new chunks, but it's significantly better than the 100-200 block borders you could get without it.
CliffTree Compatibility
On 1.21.x, Tectonic now natively supports CliffTree! Just install both as mods and you're set.
Rougher Terrain
Tectonic used to smoothen out the terrain, removing the staircasing/"lerp" that is present in vanilla. This has been reverted. This has been done for a few reasons:
- Windswept terrain better integrates with the rest of the world.
Slopes are easier to build on, with median areas at each staircase step.
Grove generation around mountains is improved.
Strange horizontal strips parallel to mountain faces are far less noticeable.
The underlying noise that makes Tectonic work is better obfuscated, making terrain less predictable.
Underground Rivers
Underground rivers got a massive overhaul in the Everest update, much closer matching my standalone Underground Rivers mod.
Terrain inside of rivers varies significantly more. This includes varying sizes and shapes.
Transitions between normal and underground rivers have been improved. The transition point has been moved further from mountains to make the terrain drop less steep, and the varying sizes mean the ceiling is no longer consistently super flat at entrances.
Entrances are significantly taller than before, sometimes being more blocks tall than wide.
Pillars are significantly more common.
Significantly reduced aquifer issues at the sides of the rivers.
[Mod Only] Increased glow lichen rates from Tectonic v1 have returned.
Lava Tunnels
The deep lava sibling of underground rivers got some love!
Lava tunnels are noticeably rarer than before. They still generate quite a bit, but not as pervasively.
The size has been significantly shrunken down. They now have rougher, narrower walls, smaller ceilings, and less safe ground. Proceed with caution.
The direction of tunnels twists and turns more often, making the underlying noise less visible and sightlines more obscured.
Plateaus
The plateau terrain from v2 has been completely ripped out. The new plateaus can be 2 or 3-tiered, with occasional gentle "onboarding ramps" for easier survival exploration.
Desert Dunes
Dunes have been rewritten again in the version, looking even more like actual dunes than before.
Oceans
Ocean terrain is significantly more varied than before. Deep oceans in particular have seen special terrain introduced, causing overhangs and trenches to generate!
Swamps
Swamp bones sit much closer to sea level, generating much more like in vanilla.
With Terralith installed, inland swamps near mountains have been removed.
Windswept Savannas
There should no longer be large, flat regions of the Windswept Savanna biome.
Oceanside Cliffs
The overhangs have been removed.
With Terralith installed, these cliffs will actually generate the mod's special cliff biomes.
World Presets
[Mod Only] Removed the Amplified and Large Biomes presets from the world type selector.
Amplified has never worked with Tectonic, either completely ignoring it or having unintended behavior.
Large Biomes is redundant due to the new temperate/vegetation related config options. This also drastically reduces the amount of duplicated code needed for the mod to fully function.
Deep Dark
The Deep Dark biome is now capped at y32.

Transitions between normal and underground rivers have been improved. The transition point has been moved further from mountains to make the terrain drop less steep, and the varying sizes mean the ceiling is no longer consistently super flat at entrances.
Entrances are significantly taller than before, sometimes being more blocks tall than wide.
Pillars are significantly more common.
Significantly reduced aquifer issues at the sides of the rivers.
[Mod Only] Increased glow lichen rates from Tectonic v1 have returned.
Lava Tunnels
The deep lava sibling of underground rivers got some love!
Lava tunnels are noticeably rarer than before. They still generate quite a bit, but not as pervasively.
The size has been significantly shrunken down. They now have rougher, narrower walls, smaller ceilings, and less safe ground. Proceed with caution.
The direction of tunnels twists and turns more often, making the underlying noise less visible and sightlines more obscured.
Plateaus
The plateau terrain from v2 has been completely ripped out. The new plateaus can be 2 or 3-tiered, with occasional gentle "onboarding ramps" for easier survival exploration.
Desert Dunes
Dunes have been rewritten again in the version, looking even more like actual dunes than before.
Oceans
Ocean terrain is significantly more varied than before. Deep oceans in particular have seen special terrain introduced, causing overhangs and trenches to generate!
Swamps
Swamp bones sit much closer to sea level, generating much more like in vanilla.
With Terralith installed, inland swamps near mountains have been removed.
Windswept Savannas
There should no longer be large, flat regions of the Windswept Savanna biome.
Oceanside Cliffs
The overhangs have been removed.
With Terralith installed, these cliffs will actually generate the mod's special cliff biomes.
World Presets
[Mod Only] Removed the Amplified and Large Biomes presets from the world type selector.
Amplified has never worked with Tectonic, either completely ignoring it or having unintended behavior.
Large Biomes is redundant due to the new temperate/vegetation related config options. This also drastically reduces the amount of duplicated code needed for the mod to fully function.
Deep Dark
The Deep Dark biome is now capped at y32.

The largest Tectonic update ever is here. A full rewrite, a plethora of new terrain types, and improvements to almost all existing features. This is the Everest update.
Made with love by Apollo. 💜
Config Overhaul
[Mod Only] There is now a config screen for viewing and changing Tectonic options in-game! Every option has an explanatory tooltip and its default value displayed. The tooltips replace the comments in the config file to reduce clutter.
This also comes with 16 new config options. Please see the config screen for more information on these.
Continents and Islands
Terrain in v2 was split roughly 50/50 between land and ocean, with no coherent shape for either. In v3, terrain now forms into more coherent "continents".
Continents will generate thousands to tens of thousands of blocks wide, designed for Tectonic's massive mountain ranges and new terrain types.
In the oceans between continents, you'll find relatively smaller "islands". These range from a few hundred blocks to around a thousand blocks across. These islands use vanilla's mountain terrain shaping, now making it possible to find traditional mountain rings. With Terralith installed, these islands have Volcanoes and Calderas!
[Mod Only] A config option to remove the random normal ice in Frozen Oceans has been added to help with ocean exploration in the new bigger oceans.
Jungle Pillars
Some jungle biomes will generate towering pillars covered in vegetation stretching upwards of a hundred blocks high!
Biome Valleys
Sometimes, you will find cherry groves and pale gardens nested inside of a valley!
Badlands Canyons
Some badlands will feature massive canyons, carved around rivers.
Badlands Buttes
Other badlands will generate isolated plateaus in an otherwise flat, desolate region. These are a perfect place to find red sand, which could be difficult to get in older versions.
Wetlands
Some forests, taigas, and jungles will feature very flat terrain with frequent ponds and small lakes.
Rolling Hills
Some plains, flower forest, and ice spikes will feature very smooth rolling hills.
Chunk Blending
Tectonic v2 worlds will blend into Tectonic v3 worlds (somewhat) smoothly! There will be 1-5 block seams at the border between old and new chunks, but it's significantly better than the 100-200 block borders you could get without it.
CliffTree Compatibility
On 1.21.x, Tectonic now natively supports CliffTree! Just install both as mods and you're set.
Rougher Terrain
Tectonic used to smoothen out the terrain, removing the staircasing/"lerp" that is present in vanilla. This has been reverted. This has been done for a few reasons:
- Windswept terrain better integrates with the rest of the world.
Slopes are easier to build on, with median areas at each staircase step.
Grove generation around mountains is improved.
Strange horizontal strips parallel to mountain faces are far less noticeable.
The underlying noise that makes Tectonic work is better obfuscated, making terrain less predictable.

This is the first beta of Tectonic v3, the second rewrite in Tectonic's history.
Please take note of the following missing features:
- Terrain Blending (will be introduced later)
- Terralith compatibility (will return later)
- Large Biomes compatibility (will return later)
- Continents compatibility (may not return later)
- Lava Rivers (may not return later)
Continents and Islands
Terrain in v2 was split roughly 50/50 between land and ocean, with no coherent shape for either. In v3, terrain now forms into more coherent "continents". Continents will generate thousands to tens of thousands of blocks wide to account for the massive mountain ranges and new terrain types.
In the oceans between continents you'll find relatively smaller "islands", ranging up to around a thousand blocks across. These islands use vanilla's mountain terrain shaping, now making it possible to find traditional mountain rings.
New Terrain Types
Tectonic now features several new terrain shaping types to spice up your travels.
While Tectonic v2 did feature three-tiered plateaus, v3 polishes this feature up significantly. There are now both two and three-tiered plateaus, with both sometimes having smoother slopes to climb up them in survival more easily.
While plateaus usually elevate plateau biomes, some Cherry Groves and Pale Gardens have the plateaus surround the biome, turning the biome into a valley.
Some forest, jungle and taiga biomes generate very close to sea level and generate frequent ponds and lakes.
Some badlands form massive canyons with rivers running through them.
Badlands that don't generate canyons will instead have low terrain with occasional isolated plateaus.
Some plains, flower forest and ice spike biomes will feature smooth rolling hills.
Dunes have been overhauled in v3, looking much closer to the new rolling hill terrain.
Some jungles feature massive pillars that can extend upwards of a hundred blocks tall, reminiscent of the Zhangjiajie National Forest Park in China.
Deep oceans are much more varied than before, having dynamic heights and sometimes generating overhangs and deep trenches.
Config Overhaul
The config has gotten another overhaul, with several new options. On top of that, there is finally a config screen!
Improved Underground Rivers
Underground rivers have received a full rewrite, largely based off of my standalone Underground Rivers mod.
Terrain inside of rivers varies significantly more. This includes varying sizes and shapes.
Transitions between normal and underground rivers have been improved. The transition point has been moved further from mountains to make the terrain drop less steep, and the varying sizes mean the ceiling is no longer consistently super flat at entrances.
Entrances are significantly taller than before, usually being more blocks tall than wide.
Pillars are significantly more common.
[Mod Only] Increased glow lichen rates from Tectonic v1 have returned.
Seaside Cliff Changes
Less Smooth Terrain
Vanilla's noise used to roughen up terrain that has the inadvertent affect of making sloped terrain "staircase" has been reintroduced. This has been done for a few reasons:
Windswept terrain better integrates with the rest of the world.
Slopes are easier to build on, with median areas at each staircase step.
The underlying noise that makes Tectonic work is better obfuscated, making terrain less predictable.
Improved Windswept Savannas
Windswept Savannas have received a significant upgrade. While in previous versions you could find sizable areas of flat areas of the biome, that should no longer happen.

The config has gotten another overhaul, with several new options. On top of that, there is finally a config screen!
Improved Underground Rivers
Underground rivers have received a full rewrite, largely based off of my standalone Underground Rivers mod.
Terrain inside of rivers varies significantly more. This includes varying sizes and shapes.
Transitions between normal and underground rivers have been improved. The transition point has been moved further from mountains to make the terrain drop less steep, and the varying sizes mean the ceiling is no longer consistently super flat at entrances.
Entrances are significantly taller than before, usually being more blocks tall than wide.
Pillars are significantly more common.
[Mod Only] Increased glow lichen rates from Tectonic v1 have returned.
Seaside Cliff Changes
Less Smooth Terrain
Vanilla's noise used to roughen up terrain that has the inadvertent affect of making sloped terrain "staircase" has been reintroduced. This has been done for a few reasons:
Windswept terrain better integrates with the rest of the world.
Slopes are easier to build on, with median areas at each staircase step.
The underlying noise that makes Tectonic work is better obfuscated, making terrain less predictable.
Improved Windswept Savannas
Windswept Savannas have received a significant upgrade. While in previous versions you could find sizable areas of flat areas of the biome, that should no longer happen.

The Config Update
- Added a proper config to the mod version at config/tectonic.json, with three categories to play around with.
- Legacy: Controls the legacy mode, which was introduced earlier in v2.1 to allow safe upgrading of Tectonic v1 worlds.
- Features: Allows some features of the mod to be toggled on and off. This includes deeper oceans, underground rivers, lava rivers, and desert dunes.
- Experimental: Adds some extra configuration options just for fun. It includes the following:
- An increased height setting, which will increase the overworld's build and generation limits to y640.
- A terrain scale setting, which will vertically scale the terrain by a given factor. Combined with the increased height setting, you can make mountains stretch to over 500 blocks tall.
- A horizontal mountain scale setting, which horizontally scales mountains (how shocking). This can make mountains thicker and more spread out.
- On top of these three categories, there's a setting for if the mod is enabled. Tectonic will lie dormant and not affect the game if this is turned on.
There's been a lot of backend work going on to make the update possible. As a result, there's been some merges and splits of mod jars.
a. The multi-loader 1.20.1 and 1.19.2 versions have been split into separate Fabric and Forge versions.
b. The Fabric 1.19.3-1.20.1 and Fabric 1.20.2+ versions have been merged into a single version.

Other than bug fixes, this will likely be the last version of Tectonic until Minecraft 1.20 releases. My time and effort is going to be spent on other projects.
Additions
- Added stone generation to steeper areas of the terrain. In Savannas and Jungles, this is packed mud instead.
Changes
- Sugarcane placement has been increased where sand generates, and the amount of sugarcane per patch on average has increased.
- This change has been made to combat the fact that biomes in Tectonic without sand generation do not have sugarcane at all.
- Clay now generates in rivers and is not just limited to Lush Caves and Swamps.
- Fixed an issue with strange riverbed generation in modded biomes. These will now use vanilla's disks of sand, gravel, and clay instead of just dirt.

First minor update to Tectonic, with bug fixes and a major change to biome placement.
If you want to update a world from Tectonic v1.0.0 to Tectonic v1.0.1, install the "Tectonic 1.0.0 Compatibility" datapack and install it into your datapack folder after updating to 1.0.1. If you do not do this, you will have some nasty chunk borders.
