    About

    Dynamic Surroundings is a client-side mod that enriches Minecraft’s vanilla atmosphere with environmental sound and visual effects, and can be used in modpacks or while playing on vanilla servers. It blends biome ambience as you move between areas, with examples including wind in mountains and deserts, birds and insects in forests, nighttime crickets, and cave rumble; sounds can also gain reverb or muffling based on the surrounding space and blocks. Players can control individual sounds, including blocking them, culling them, adjusting their volume, and previewing them, while sound remapping can substitute effects such as footsteps. Environmental effects include fog that varies with biome, time, and weather; flame jets over lava; steam where hot blocks meet water; and waterfall splashes, mist, foam, and sound. In cold, icy, or taiga biomes, an aurora can appear in the northern night sky, and glowing fireflies can flicker around flowers at night. Most effects can be adjusted or turned off, and Serene Seasons can influence temperature-dependent effects such as frost breath, precipitation, and some biome sounds.

    Security

    No harmful code found

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

    What it can do on your computer

    Uses folders outside the game
    It can read or write files outside your Minecraft folder, on the rest of your computer. Found: your user folder.
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them.
    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 full in its code. See Privacy
    Starts other programs
    It can start another program on your computer, for example to open a link in your browser. Only in its files for Fabric 1.20.1.

    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 14 latest files checked, last on 21 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.
      14 latest files: the newest file for each Minecraft version and loader. The answer above is about the 3 for recent versions. 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.
    • Uses folders outside the game
      Finds the Minecraft folder.
    • Starts other programs
      Purpose not known.
    • Looked for, not foundWe looked for these in the file and did not find them.
      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 · All 3 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 3 files, 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

    AI was used for its code and assets

    The author declares AI code and assets on Modrinth.

    The author writes that AI was used.

    Claude Code is named in the files of its repository.

    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 · 8 places read
    • 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.
