About
Concurrent Chunk Management Engine (Forge) is an unofficial Forge port of C2ME that improves chunk processing to make exploration and world pre-generation faster on multi-core systems. It parallelizes terrain, biome, feature, and structure generation, along with chunk loading, saving, and lighting, while using smarter scheduling and lower allocation overhead. Its no-tick view distance lets players see farther without ticking the additional chunks, and it includes thread-safety fixes for vanilla structure generation. The mod is divided into individually toggleable feature modules and is designed to work alongside Forge performance mods such as Embeddium, ModernFix, FerriteCore, ServerCore, and Canary, stepping aside where another mod already handles overlapping optimizations. The 1.18.2 build also includes the Starlight lighting engine and automatically tunes its world-generation workload to the hardware; it disables its Starlight component if standalone Starlight is present. On 1.18.2, it recognizes thread-unsafe world-generation mods including Lost Cities, Blueprint, Large Ore Deposits, Skyblock Builder, and Ore Tweaker, serializing only the affected generation stage so other work can continue in parallel.

Security
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. No web address is written in its code. 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
- 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.2 latest files: the newest file for each Minecraft version and loader. The answer above is about the one 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
- Looked for, not foundWe looked for these in the file and did not find them.Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
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
- 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
No sign that AI was used to make it
We looked for AI tools in its texts, files and images and found none.
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.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Not on Modrinth.
