How to install Create Optical

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 1.20.1–1.21.1 on Forge or NeoForge automatically.

  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 create_optical-0.4.2.jar (7.6 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.

  4. Launch the loader profile

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

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