Modding

Add community-made robots and modpacks to MoSim, or build and share your own.

Only install mods you trust. Mods include DLL code that runs on your computer.

How mods work

  1. 1

    Get the mod folder

    Each mod is one folder with three files:

    • MyModPack.bundlemodels, textures and other assets
    • MyModPack.dllthe robot's code
    • catalog.jsoninfo about the mod
  2. 2

    Put it in the mods folder

    MoSim loads every mod in this folder when it starts.

    %userprofile%\AppData\LocalLow\CascadeStudios\MoSimulator\Mods
  3. 3

    Pick it in game

    Choose your mod from the Modpack dropdown in the play menus. Runs with a mod are marked “Modded”.

Browse verified mods created by the MoSim community. All mods are reviewed before appearing here.

  • Include the .bundle, .dll and catalog.json
  • Windows, macOS and Linux builds are all required
  • Reviews usually take 24–48 hours
