Treeplacer Wyther's Addon — Minecraft Mods

From Modrinth

Treeplacer datapack to grow trees from William Wyther's

Overrides for: acacia, azalea, birch, dark oak, brown mushroom, jungle, mangrove, oak, red mushrooms, spruce

Every biome now has a mega version of each. Dark oak has a singular version for all biomes.
Flowering azalea is untouched to allow for normal azalea trees.
Overrides chosen required some interpretation at times as leaves and wood did not always match, when this was the case leave type determined the sapling. There are a few exceptions to this, most single jungle overrides actually have azalea leaves and a few random ones here and there. These occur when two trees use the same leaf type in a biome but are still distinctly different tree shapes.
Almost all trees are represented, there are one or two outliers. Experiment or check source files.

If you have feedback of any kind, message me, make a comment, github issue, just contact me in any form you can find.
