About
Weather Flux brings simulated severe weather to Minecraft, with weather events that form and move through the world rather than remaining static. Its weather systems include supercells, squall lines, blizzards, sandstorms, changing wet and dry regimes, hail, lightning, and thunder, with snow and sand that accumulate over time. Tornadoes have volumetric funnels, wind fields, width-scaled travel speeds, and can merge; their winds can destroy blocks according to wind thresholds, scour and debark terrain, and carry debris, while block reinforcement offers protection. Players can monitor conditions with radar blocks and a tablet, including reflectivity, wind velocity and speed, and cloud coverage maps, as well as warning polygons, tornado sirens, and emergency alert radios. Anemometers, weather vanes, wind and rain sensors, tornado probes, probe tablets, and a reinforcement wrench provide tools for observing, recording, and responding to weather. The presentation includes animated procedural clouds in ray-marched or billboard styles, custom rain and snow, rain shafts, tumbling entities and camera movement, and beacon lighting that can affect clouds; wind, rain, delayed thunder, sirens, and alert broadcasts also have dedicated sounds. The mod offers extensive customization through its configuration options.
Written from Modrinth . How we write it
In-game changes
Changes the game's code in 3 areas: World renderingChanges 1 game code file in this area: drawing the terrain, sky, clouds and weather., User interfaceChanges 1 game code file in this area: menus, screens, tooltips, the chat window and the in-game overlay. and Server and world logicChanges 1 game code file in this area: the world, commands, scoreboards, saved data and game rules..
Adds 14 blocks, 5 items, 3 entities, 16 recipes, 18 sounds and 7 key bindings.
Counted from the names and data files in the mod, so the list may not be complete.
Replaces 3 of vanilla Minecraft's core shaders.
Details
Security
No harmful code found
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.
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.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
- 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.
- 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
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
- 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 that AI was used to make it
We looked for AI tools in its texts, files, images and sounds 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.No AI content or AI features declared.
