    About

    Nether Core expands the Nether with resources, building materials, and machinery intended to make it a more appealing place to settle and develop. Vanilla ores can generate in the Nether, while Netherrack can be compressed through eight tiers and the highest tier smelted into a Nether Star, at the cost of roughly 43 million Netherrack. Nether Stone adds decorative block variants, including slabs, fences, stairs, and bricks, and Soul Glass offers a frameless, light-blocking window with visible trapped souls. A Nether Rod crafted from a Blaze Rod and Nether Brick provides Glowstone-level light. Nether Growth can be applied to Netherrack in the Nether, where it slowly spreads to nearby blocks and may set them on fire; it also prevents mob spawns. When Nether Growth spreads to Coal Ore, it can create Nether Coal Ore, a source of Nether Coal that burns twice as long as ordinary coal. The Nether Furnace smelts items without fuel by drawing heat from nearby lava, and receives an additional heat boost when placed in the Nether; more heat increases its passive smelting speed.

    Written from CurseForge and the GitHub README . How we write it

    In-game changes

    Adds 2 items: Nether Coal and Nether Spore.

    Counted from the names and data files in the mod, so the list may not be complete.

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

    Security

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.8.9 to 1.10.2.

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

    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 4 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.
      4 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. 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.

    • Looked for, not foundWe looked for these in the file and did not find them.
      The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.8.9 to 1.10.2.

    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 · All 4 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 4 files, for Minecraft 1.8.9 to 1.10.2. See each file in Releases

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its description, files, images and code history and found none.

    We have not read its changelogs 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.
