Treeplacer
Saplings can dynamically generate different trees, based on the biome they are grown in, declared in data files.
About this Mod
Ever played with a mod, such as Terralith or William Wythers' Overhauled Overworld, that add custom trees to world gen that you can't grow?
With Treeplacer you can create a custom datapack that allows you to change saplings to grow into whatever tree your heart desires!
Features include:
- Change a sapling's tree for all biomes,
- Change a sapling's tree based on biome,
- Change a sapling's tree based on the block it is grown on.
- Define a 2x2 tree that uses the rules above on all saplings, even mushrooms!
To get started take a look at the wiki on github.

Treeplacer server crashes on startup – what to do?

Treeplacer officially supports fabric, forge, neoforge for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Treeplacer – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Treeplacer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
