About this Mod

CustomTree

CustomTree is a modern world-generation mod for Minecraft that replaces vanilla trees with custom-made and carefully designed NBT structures. The mod enhances forests and natural environments with more detailed tree generation while trying to maintain compatibility with other mods as well as world generation performance.

Features

  • Replaces vanilla trees with custom NBT-based variants
  • Unique tree generation across all supported biomes
  • Full compatibility with Tectonic
  • Server-side support with no client installation required
  • Lightweight and optimized for modpacks and multiplayer servers, coming in at only 1 MB total

Compatibility

While I try to maintain compatibility with different mods, I cannot promise that every mod will work. Especially mods that modify tree generation or add their own trees will probably not be compatible with this mod.

Compatible Mods

  • Tectonic
  • C2ME

Updating to Other Versions

The goal of this mod is to support nearly every modern Minecraft version. However, please keep in mind that updating and porting a mod to newer Minecraft versions takes time, especially as Mojang frequently changes internal game code and world generation systems.

At the moment, I am primarily focused on supporting newer Minecraft releases and do not currently plan to backport the mod to significantly older versions in the near future.

If you would like to use the mod on an unsupported older version, you are free to decompile and port the mod yourself in accordance with the project's license.

Frequently Asked Questions

CustomTree server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Is CustomTree compatible with fabric?

CustomTree officially supports fabric for Minecraft 26.1.2, 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with CustomTree – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if CustomTree consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
