    About

    c2me Au Naturel edition is a fork of C2ME, a concurrent chunk engine that parallelizes Minecraft world generation, with changes focused on performance, stability, and compatibility for the Au Naturel modpack and its included mods. It addresses issues such as deadlocks, lost wakeups, thread-pool exhaustion, and queue-counter races, including fixes for hangs during world creation when other mods access chunks. To reduce contention with entity-heavy mods, spawn-chunk processing is kept single-threaded; the fork also includes fixes for Stronghold and Nether Fortress generation. Additional optimizations reduce allocations in aquifer calculations and chunk serialization, improve cache eviction, and streamline lighting and block-entity serialization.

    No harmful code found

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

    What it can do on your computer

    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Found in 4 libraries it includes. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file in your config folder.

    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 · The latest file 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.
      1 latest file, for a recent version. 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

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    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 · Its one file 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 its one file, for recent Minecraft versions. See each file in Releases

    AI

    AI was used for its code

    Claude (chat) is named in the author's texts.

    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.
