Treeplacer

Saplings can dynamically generate different trees, based on the biome they are grown in, declared in data files.

Treeplacer

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?

Treeplacer allows for the creation of custom datapacks that allow you to change what a sapling grows into based on its growing conditions.

Features include:

Changing a sapling's tree for all biomes
Change based on selected biome
Change based on block grown on, globally or per biome
Weighted randomization of saplings grown
Change based on world position such as y level
Define 2x2 trees even for saplings that do not naturally have them
Change large mushrooms (they are internally trees)

To get started take a look at the wiki on github.
