Minecraft Mod Texture Upscaler

Most mods ship with custom textures that are the default 16x textures that Minecraft uses. When playing with a resource pack such as Faithful 32x, these custom textures can look out of place.

This simple tool will extract all textures from a mod's jar file and upscale them using the Scale2x algorithm. They will be output to a directory that can be zipped and used as a resource pack in game. The upscaled textures will override the default 16x textures in the mod's jar file.

Dependencies

• Scale2x
  • scalerx must be installed and in your PATH
  • If on Windows you can extract it to ./scale2x

Usage

1. Create an output directory
2. Create an .mcmetadata file in the output directory with the following:

"pack": {
    "pack_format": 15,
    "description": "32x custom resource pack"
}

3. Run the main.py script (scale factor is 2 by default):

python main.py <input jar> <output dir> [scale factor]

e.g.

python main.py ../supplementaries-1.20-2.8.17.jar ../my_custom_pack-32x-1.20.1 2

4. Zip the assets directory and pack.mcmeta in the output directory and that's the resource pack ready to be used in game!
