    About

    Chunksmith pre-generates Minecraft terrain within a chosen area so players can explore without waiting for chunks to generate as they travel. Its adaptive throttle adjusts generation to server tick health and online players, and can pause and resume a run when the server is struggling, helping keep multiplayer playable during generation. When Distant Horizons or voxy is installed, Chunksmith builds level-of-detail terrain data during pre-generation, so players can see distant terrain without a separate generation pass. It can serve that data to multiplayer clients, allowing them to view pregenerated terrain beyond places they have visited; the server and client use the same project, with the client’s renderer drawing the terrain. If a world was pregenerated before a renderer was installed, rerunning the task can build LOD data from existing chunks without regenerating them, and completed LOD work is skipped. An optional horizon mode generates LOD beyond a chosen radius and discards those distant chunks instead of saving them, reducing world storage while retaining the distant view; chunks near players are kept. To give other world-generation mods time to place structures, Chunksmith can hold new chunks until their eight neighbors exist, and it can report overreach and attribute structure faults. Pre-generation supports shapes including circles, squares, diamonds, triangles, and stars, centered on coordinates, world spawn, or the world border, with multi-world runs, progress and ETA reporting, pausing, resuming, cancellation, and world trimming. Settings can be changed while the game is running, and an unfinished task can optionally resume after a restart.

    Written from Modrinth . How we write it

    In-game changes

    Changes the game's code in 5 areas: Chunk loading and storageChanges 5 game code files in this area: how the game loads, tracks, saves and unloads chunks., Server and world logicChanges 4 game code files in this area: the world, commands, scoreboards, saved data and game rules., World generationChanges 2 game code files in this area: terrain, biomes and structures made when new land is created., Mobs and their behaviorChanges 2 game code files in this area: mobs, animals, villagers, projectiles and how they move and act. and Other game codeChanges 1 game code file in this area: game code that is not in one of the areas above..

    Adds no new blocks, items or other content.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Accepts connections from other computers
    It can accept connections from other computers.
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Fabric 1.20 to 26.3; NeoForge 1.21 to 26.3; Forge 1.20.1 to 1.21.11.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. No web address is written in full in its code. See Privacy

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · All 40 latest files checked, last on 16 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      40 latest files: the newest file for each Minecraft version and loader. The answer above is about the 32 for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.
      Nothing declared about your system outside the game.
    • Accepts connections from other computers

    Privacy

    Sends usage statistics

    Sent to bstats.org.

    Only some of its files send usage statistics.

    We found this in its code, read without running it.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · All 32 files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of all 32 files, for recent Minecraft versions. See each file in Releases

      Sends usage statistics.
      Usage statistics
    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Purpose not known.Unencrypted (http)Plain http: what is sent to this address is not encrypted on the way.
      Nothing about you
    • Named in its filesA crash report or usage data service named in the files of the mod. The code does not show when or what is sent.
      The code names bStats, a service that receives usage data.
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its texts, files and images and found none.

    We have not read its code history yet.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
