Arboria is a world generation datapack that improves most vanilla overworld biomes. The datapack's goal is to aesthetically overhaul the world without changing the progression too much.
This datapack is made for Minecraft Java 26.1+.
For older versions visit the Modrinth page.
FEATURES
Arboria adds:
In general, blocks that generate in a biome are blocks you could obtain by only playing in that biome (example: coarse dirt can be crafted from dirt and gravel). The only exceptions to this rule are rooted dirt and moss carpet.
COMPATIBILITY
Arboria is made for Minecraft Java 26.1. For 1.19-1.21.11 versions visit the modrinth page (old versions).
The datapack will work on any vanilla server and should work on most modded servers (fabric, spigot, paper, etc.), but I cannot guarantee that. It doesn't work on realms.
Arboria is not compatible with any datapack that modifies overworld surface biomes. It is compatible with datapacks that change nether, end or cave biomes.
Arboria works with datapacks that add new biomes in addition to vanilla biomes, such as Terralith and William Wythers' Overhauled Overworld. Just make sure Arboria has a higher load priority (put it above Terralith/WWOO when adding datapacks to your world).
Note that the biomes were not designed to be used with other worldgen datapacks and may look out of place with surrounding biomes.

Have something to say?
First of all rename one of the biome files in data/minecraft/worldgen/biomes to flower_forest2.json (or any name that is not an existing biome).
In vanilla overworld biome source there are 80 entries for flower_forest. All you need to do is replace 40 of those entries with flower_forest2. You will also need to get the overworld biome source from somewhere.
