Tan's Huge Trees Mod Wiki

Tan's Huge Trees (THT) is a sophisticated world generation mod designed to overhaul the natural landscape of Minecraft. Unlike standard tree mods, THT utilizes a custom "Region Pre-Location" system that allows for the generation of massive structures up to 1,000x1,000 blocks in size, far exceeding the engine's default limits. The mod focuses on a "Fantasy" aesthetic, adding over 30 tree species with more than 600 unique shapes, ensuring that no two forests look identical.

Key features include a data-driven "Custom Pack" system similar to datapacks, allowing users to create, edit, and share tree settings. The mod also introduces "Living Tree" mechanics, where trees can decay or become dead structures based on environmental conditions or player interaction.

The mod adds a vast array of tree species, each designed with specific themes and spawning conditions. Most species feature 10-20 different shapes to provide variety.

Primary Species

Rare & Unique Species

• Empyrean Tree (Redwood): Found in Old Growth Pine Taiga; these are the tallest trees in the mod.
• Kronos Tree (Guard Tree): A massive, ancient-looking tree with a unique protective aesthetic.
• Monolith Tree: A rare, stone-like tree structure found in Desert biomes.
• Helios (Tree of Sun): A giant, radiant tree that serves as a landmark in bright biomes.
• Tree of Wisdom: A rare, mystical tree found occasionally in Plains biomes.
• Karma: A high-tier fantasy tree introduced in later versions (1.8.0+).
• Apple Trees: Decorative trees found in Pasture fields that can drop apples.
• Palm Trees: Specifically designed to spawn near water (Waterside type) in tropical biomes.

Beyond living trees, the mod generates various natural elements to make the world feel more lived-in and detailed.

• Coarse Woody Debris: Fallen logs and decaying wood found on the forest floor.
• Dead Trees: Trees can generate in various states of decay, including hollow trunks, twigless skeletons, or completely fallen logs.
• Stumps & Roots: Detailed ground-level structures that connect trees to the terrain.
• Bushes & Rocks: Small decorative features that fill the gaps between massive trees.
• Leaf Litter: Custom ground cover that simulates fallen leaves (available as a TXT function in custom packs).

While the mod primarily uses vanilla blocks to ensure compatibility, it adds several specialized items for interaction and creative use.

Tree Generator

The Tree Generator is the core tool for manual tree placement. It is a block/item used to spawn specific tree species instantly. In creative mode, it allows players to test custom shapes and pack settings.

Tree Summoner Staff

A "just for fun" item that allows players to summon trees at a distance.

Custom Saplings

The mod includes built-in saplings for survival mode. These can be planted like vanilla saplings but will grow into the massive versions defined by the mod's generation system.

The Sapling Trader is a unique entity that provides access to the mod's custom saplings in survival mode.

• Summoning: To summon the Sapling Trader, place Flowering Azalea Leaves into a Campfire.
• Behavior: He acts as a specialized wandering trader, offering blueprints and saplings for various huge tree species in exchange for emeralds or other nature-related items.
• Customization: The trader's trades and appearance can be modified via the Custom Pack system.

Living Tree Mechanics

Trees in this mod are not static blocks; they have a "Living" status.

• Decay: If a tree's leaves are entirely removed or its "core" (the junction between roots and trunk) is destroyed, the tree will transition into a "Dead Tree" state.
• Dormancy: Trees can enter a dormant state (e.g., during winter if using Serene Seasons) to prevent them from dying when leaves naturally disappear.

Generation System

THT uses a "Region Pre-Location" system. When a new region is loaded, the mod pre-calculates tree positions. This prevents the lag associated with standard structure generation and allows for trees that span multiple chunks.

Spawn Types:

• Normal: Standard land generation.
• Waterside: Spawns specifically near water blocks (e.g., Palm trees).
• Landside: Spawns on the edge of land looking toward water.
• Shoreline: Spawns directly on the coast.

The mod is highly customizable through its own pack system, located in the config/tanshugetrees/custom_packs folder.

• Structure: Users can create folders or ZIP files containing JSON definitions for tree shapes, species, and spawning rules.
• Main Pack: The mod requires the "TannyJung's Main Pack" (often renamed to #main), which contains the default tree data. This pack can be updated automatically via the internet to provide new tree shapes without updating the mod JAR.
• Commands:
  • /TANSHUGETREES restart: Reloads all custom packs and configurations.
  • /TANSHUGETREES summon_tree <path>: Manually spawns a tree from a specific pack (e.g., #main/redwood).
  • /TANSHUGETREES config repair: Fixes common configuration errors automatically.

Tan's Huge Trees is designed to work alongside major world generation and aesthetic mods:

• Biomes O' Plenty / Regions Unexplored: The mod includes built-in support to spawn its trees in modded biomes (e.g., Baobabs in Savanna variants).
• NoCubes: Includes a "Block Connector" system to ensure tree trunks look smooth and connected when using the NoCubes mod.
• Distant Horizons: Compatible with LOD generation, though it is recommended to use "Full" or "Internal Server" mode to prevent tree pop-in issues.
• Serene Seasons: Trees respect seasonal changes, and the dormancy mechanic prevents them from decaying during leaf-loss seasons.
