Texpack is a C# tool to build textures from the game art repository. Texpack takes a json as input. The json tells Texpack where the art is, what art to pack, and how to pack it. See texpack/texjson.py for input json generation, json structure, and Texpack customization options. Texpack outputs a json that maps each image filename to information such as what texture the image was packed in where it is within the texture.
