Oh The Trees You'll Grow Mod is a Minecraft library mod that enables configurable custom tree generation from structure template .nbt files for Minecraft Fabric, Forge, NeoForge, and Quilt. It provides a reusable tree system for both players running modpacks and modders building worldgen content.
Tree generation is one of those areas where modpacks often feel inconsistent: great biome ideas can be held back by limited tree tooling, while custom trees can be hard to manage across loaders. This library solves that by giving a structured, template-driven system focused on configurability and reuse, instead of one-off tree setups. For players, that usually means smoother dependency handling when running big worldgen packs; for creators, it means faster iteration and cleaner tree definitions. With more than 5 million downloads on Modrinth, it has clear social proof as a widely adopted foundation in the Minecraft modding ecosystem.
Key Features of Oh The Trees You'll Grow Mod
- Template-based tree creation with
.nbtfiles — Trees can be authored from Minecraft structure templates, which gives creators a practical way to shape trunk, canopy, and extra details without hardcoding everything. This matters because visual control is much higher when your tree layout comes from an editable template. It also makes tree work easier to reason about when you are debugging worldgen behavior in a pack. - High configurability for users and modders — The library is designed around flexibility, so the same core system can support many tree styles and generation needs. That matters in real packs where one size rarely fits all biomes. Instead of replacing your worldgen direction, it helps you tune trees to match it.
- Built as an easy tree system, not just a one-off dependency — It was created to be approachable for both end users and content creators, so teams can share a common approach to tree generation. In practice, this reduces friction when multiple mods or datapack pieces need consistent tree behavior. The result is a cleaner workflow than piecing together unrelated methods.
- Proven use in major worldgen ecosystems — The project was originally made for Oh The Biomes You'll Go, which is a strong signal that it was built for large-scale biome-driven use. That matters because tree systems get tested hardest in varied terrain and broad biome sets. If your pack leans into exploration, this background is especially relevant.
- Vanilla client compatibility on servers using the library — Vanilla clients can connect to a server that uses this library, which helps reduce multiplayer setup friction. This matters for communities where not every player keeps a full modded client ready. It can make onboarding easier when server-side worldgen tooling is part of your stack.
- Recent feature growth in NBT and blockstate handling — Recent updates add Tree From Structure NBT v2, support for blockstate providers from blocks in NBT, and multiple leaf targets/providers. This matters because advanced tree variants need more than static blocks to look natural across biomes. These changes give creators finer control while keeping everything in the same template-driven pipeline.

How to Install Oh The Trees You'll Grow Mod
- Pick your loader first: Fabric Mod Loader, Minecraft Forge, NeoForge, or Quilt Loader.
- Match the mod file to your exact Minecraft version (for example 1.21.11, 1.21.10, or another listed build).
- Download the correct release for your loader and place it in your game's
modsfolder. - Launch Minecraft with the same loader profile and verify the mod is detected on the mods screen or in your pack logs.
- If another mod requires this library, keep both on matching game versions to avoid dependency errors at startup.
