UndertaleModTool

Description


UndertaleModTool, often abreviated UMT, is the main tool you will be using to create mods.

As the name implies it was initially made for Undertale, but works well with Stoneshard since both of them were made with the same game engine, Gamemaker Studio.

We use UndertaleModTool to open and edit the data.win file, which contains all of the game's data.

Download


You can find the latest version of UMT over on Github.

It's recommended to grab the latest Bleeding Edge release for your operating system, as development is fairly active and developers are fixing issues often.

Usage


Locate your data.win file, which should be in your game installation directory.
By default :

  • Steam : C:\SteamLibrary\steamapps\common\Stoneshard
  • GOG : C:\Games\Stoneshard

Once found, simply double click on it to open it with UndertaleModTool.
