Resetting Studio

To put Studio back how it was first installed, close it and delete studio.json, maps.json and model.json. Your projects, prefabs and captures are not touched.

From GoMMO Art and GoMMO Maps

The first time Studio runs, it copies GoMMO Maps' settings and GoMMO Art's settings into its own, and adds GoMMO Art's recent clients to the start screen. It never changes the old programs' folders.

  • GoMMO Maps projects in Documents\GoMMO Maps\Projects\ open with Open project as they are.
  • GoMMO Art mod folders in Documents\GoMMO Art\Mods\ are not read. Copy what you want into a project's files\client folder, keeping the same paths, to use it in Studio.
  • Prefabs in Documents\GoMMO Maps\Prefabs\ can be copied into Studio's prefab folder as they are.
