About
Underground Materials expands Minecraft’s underground exploration and building options with new ores, materials, armor, tools, food, and decorative blocks. Its cave and world-generation resources include Ruby, Cobalt, Topaz, and Amethyst, alongside craftable Steel; their tools and armor span different strengths, from Ruby as an Iron alternative to the stronger Topaz, Amethyst, and Golden Diamond gear. Golden Emerald can be made into Mystical Apples, while the stronger Enchanted Mystical Apple grants regeneration, absorption, speed, fire resistance, and resistance. For construction, Marble and Limestone generate in the Overworld and Basalt in the Nether, with each material available as blocks, bricks, pillars, stairs, slabs, walls, fences, and gates. Mystical Icebergs can generate in cold oceans, and Mystical Ice can also be crafted from shards obtained from ice blocks; its regular form can melt near light, while its brick and other decorative forms are safe for building. Mystical Icestone, crafted from Stone and Mystical Ice, adds another family of safe building blocks with matching brick and decorative variants. Ruby, Cobalt, Topaz, Amethyst, Golden Diamond, and Golden Emerald blocks can also serve as beacon bases.

No harmful code found
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.14.4 to 1.15.2.
We checked its files and read their code, without running it.
What it can do on your computer
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 2 files 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. 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.Read without running it
- 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 1.14.4 to 1.15.2.
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
- 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 both files, for Minecraft 1.14.4 to 1.15.2. 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.
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found2 of 14 changelogs read
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found126 images read
- Code of the modThe code and files of the mod, read without running it: addresses of AI services, AI libraries, AI model files and a place for your own AI key.No AI service, AI library or AI model file30 code files read
