🌸 About CliffTree 🌸
Cliff under a Tree, or CliffTree for short, is a world generation datapack that freshens up the Overworld with brand new biomes and improvements to existing biomes, all while maintaining the spirit of vanilla!
From searing Shrublands to frigid Glacier Vallies, explore a plethora of biomes, including all-new sights such as the Oasis, the Tundra, or variations of familiar places, like the Snowy Old Growth Taiga!
Vanilla Biome Improvements
Many biomes from vanilla have been improved! Alongside overall better distribution, CliffTree makes visual changes such as terracotta on the sides of Savanna Plateaus, fallen logs on various forest biomes, more stone on the sides of cliffs, and wide Beaches reminiscent of Minecraft beta.
Improved Atmosphere
CliffTree is carefully designed with visual appeal in mind, so you'll find various tweaks to the environment such as fog distance, light tinting during sunrises and sunsets, variations in cloud colors, and much more!
⚠️ Sky Biomes (read disclaimer) ⚠️
Above the clouds, you'll find dedicated biomes where rain does not fall and stars light up even during daytime.
⚠️ Important Disclaimer: these biomes can cause issues with terrain mods, so they can be disabled via config in the mod version, or by deleting or renaming the overlay.sky_biomes directory in the datapack version. With Lithostitched, sky biomes will work with certain terrain mods like Tectonic without issue, but issues might arise if the settings are not default, especially ones related to terrain height, cloud height, and build height.
Improved Rivers and Oceans
Nearly every biome in CliffTree has new colors for water, seen across the Overworld's rivers and oceans! Dive into even deeper oceans, and swim through new underwater rock and spire formations! River floors have also been altered, improving the distribution of sand, clay, and gravel underwater to provide a nice and cohesive gradient, rather than random disks.
New and Improved Cave Biomes
Instead of surface biomes extending all the way down to the underground, CliffTree adds distinct cave biomes! You'll still find ordinary-looking caves, but you'll also find the ancient Dirt Caves, terracotta-filled Warm Caves, and deep down, the scorching magma of the Inferno!
New Tree Shapes and Foliage Rules
Foliage like grasses and flowers can now be planted on sand snow blocks! Some trees have also received a makeover, such as Birch and small Jungle trees. Saplings also have custom growth rules, with only some saplings growing up on sand and snow, and certain blocks allowing the growth of rare tree types, like Jungle bushes and Swamp Oaks!
🌸 Add-ons and Compatibility 🌸
ButterBee spices up CliffTree's ecosystems by adding new biome-dependant variants for chickens, cows, pigs, wolves, and even one new frog! This add-on will hopefully make exploration feel fresh, as you might discover new faces along your journey!
Tectonic is a world generation project that aims to transform how terrain is shaped. Terrain forms to continent-like landmasses, tailored to fit massive mountain ranges and new terrain types. Oceans feature smaller "islands", up to around a thousand blocks across!
Since Tectonic 3.0, the mod versions of CliffTree and Tectonic are natively compatible together! If you're using the datapack version, a compatibility datapack is required.
Since CliffTree 4.0, the datapack version is now natively compatible with Tectonic out of the box, but the Sky Biomes overlay directory needs to be disabled to function correctly, unless Lithostitched is installed.

🌸 Why is it called CliffTree? 🌸
This is probably obvious, but CliffTree's name originates from Island Song. I just really like Adventure Time.
