ObjToSchematic

A visual tool to convert .obj model files into Minecraft Schematics or Litematica.

Preview

Usage

You can either download the latest release or build it yourself by following the instructions below.

  • Download and install Node.js.
  • Run git clone https://github.com/LucasDower/ObjToSchematic.git in your command line.
  • Navigate to /ObjToSchematic-main.
  • Run npm install.
  • Run npm start.

Advanced

Block Palettes You can create your own block palettes to fit the build you desire. When you select this palette, the generated structure will only use the blocks defined in your palette. To create a palette, list every block you want to use in /tools/new-palette-blocks. A list of every supported block can be found in /tools/all-supported-blocks. When your list is complete, run npm run palette. If everything is successful, the next time you run the program you'll be able to select your new palette in the 'Block palette' dropdown.

Texture Atlases If you play Minecraft with a resource pack, you will probably want to build your own texture atlas. This way the program will use the same resource pack for its visualisation and more accurate colour-to-block conversions can be made. To do this, run npm run atlas and follow the instructions. If everything is successful, the next time you run the program you'll be able to select your resource pack in the 'Texture atlas' dropdown.

Debugging

To allow for your favourite debugging tools like breakpoints and call stacks, I've included launch options for debugging in VSCode. Use Ctrl+Shift+D, and run "Debug Main Process" and once the Electron window has initialised, run "Attach to Render Process".
