Treeplacer – Terralith Addon – Neoforge Port

Treeplacer – Terralith Addon (1.21.1)

Adds sapling growth support for Terralith’s custom trees. Plant a sapling in a Terralith biome and it grows the tree native to that biome instead of the vanilla one.

This is an updated port of Treeplacer – Terralith Addon by Fusion_MC, which stopped at 1.20.1. All credit for the original design and tree mappings goes to them.

Requirements

• Minecraft 1.21.1 with NeoForge
• Treeplacer 2.2.0
• Terralith 2.6.2 (requires Lithostitched)

Install it as a datapack: put the zip, unzipped, in your world’s datapacks folder.

Features

• Saplings grow Terralith’s biome-specific trees in the matching biomes.
• Covers oak, spruce, birch, acacia, dark oak, jungle, cherry, azalea, flowering azalea and mangrove, plus 2×2 variants.
• 2×2 mushrooms grow the giant mushroom variants found in Terralith biomes.

What changed from the 1.20.1 version

• Updated to data pack format 48 for 1.21.1.
• Updated feature IDs that Terralith renamed or removed, such as jungle/violet becoming jungle/amethyst, and the Shield, Yellowstone and Siberian trees.
• Oak saplings in swamps now mix Terralith’s new mangrove-style swamp tree with vanilla swamp oak, since the old swamp oak variants no longer exist.
• Removed the override of vanilla fancy_oak and the unused sapling_provider field.

Interesting

• This pairs well with Natural Propogation because it allows for modded trees to naturally spread more modded trees for some vanilla+ overgrowth themes.

Notes

• Written for Terralith 2.6.2. Other versions may have different feature names.
• Biomes the original addon didn’t cover are still not covered.
• Tree-to-biome matches were made by name and structure, so some may look different from what you’d expect. Bug reports are welcome.
