Open Loader is a utility mod that allows data packs and resource packs to be applied globally across all save files. This can be used by modpacks and servers to define custom recipes and features for a wide range of mods. It can also be used to change textures, override tooltips, and change other visual aspects of the game.
Data packs are used by vanilla minecraft to load recipes, loot tables, functions, and other game features. Many mods are also hopping on the data pack bandwagon by exposing their recipes and mechanics to the data pack system. Data Packs are loaded from the /openloader/data folder. You can provide your data packs in zipped or unzipped format. You can learn more about data packs here.
Resource packs are used to define textures, translations, sounds, and any other audio/visual asset in the game. You can use them to override assets from vanilla and mods. You can also use them to add your own textures. This can be especially useful if you're adding translations or tooltips to items or if you want to create a consistent theme and aesthetic across your mod pack. Resource packs are loaded from the /openloader/resources folder. You can provide resource packs in zipped or unzipped format. You can learn more about resource packs here.
