You can either download the latest release or if you want the latest features you can build it yourself by following the instructions below.
- Download and install Node.js.
- Run
git clone https://github.com/LucasDower/ObjToSchematic.gitin your command line. - Navigate to
/ObjToSchematic-main. - Run
npm install. - Run
npm start.

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, (make sure you run npm run build before the first time you do this). 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.
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 (make sure you run npm run build before the first time you do this) 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.
If you want to use the program without using the GUI, you can edit /tools/headless-config.ts and run npm run headless (make sure to run npm run build after each time you edit the headless-config.ts).

This is an non-commercial unofficial tool that is neither approved, endorsed, associated, nor connected to Mojang Studios. Block textures used are from Minecraft and usage complies with the Mojang Studios Brand And Assets Guidelines.
Any contributions are welcome, just fork and submit a PR! Just make sure the code style follows the rulings in the .eslintrc.json by running npm run lint and the tests all pass by running npm test.
Currently there's not much docs but if you're looking for where to get started, look at app_context.ts and follow _import(), _voxelise(), _assign(), and _export(). If you're looking to add elements to the UI, look at ui/layout.ts, I'm not using a UI framework because I'm a nutter. Adding more file formats to import from and export to would be nice. Adding new default block palettes would be great also.
If you have any questions or need help getting started then feel free to join the Discord or message me SinJi#4165.
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".
