How to install Environmental

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.19.2–1.21.1 on Forge or NeoForge automatically, together with its dependencies: Blueprint.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Forge or NeoForge

    The loader must match the game version of the mod file, for example Minecraft 1.21.1. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file environmental-1.21.1-5.0.1.jar (7.5 MB) for your game version and loader.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it. Required dependencies go there too: Blueprint.

  4. Launch the loader profile

    Open “Mods” in the main menu: Environmental should be in the list.

On a server

  1. A server on Forge or NeoForge

    The mod only works on a server with the same loader and game version, for example 1.21.1.

  2. File goes into the server’s mods folder

    Stop the server, put the mod file into the mods folder and start the server again.

  3. Use the “To server” button

    On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.

Minecraft 1.21.1 runs on Java 21: with a different Java version the game may close right after launch.
