Files included: ,json, .png, resource pack, readme files regarding sounds and font texture animation. Example uses of CustomModelData can be found within the provided coal and leather_horse_armor .json files. [ models/item/ ] – The leather horse armor is used to implement the dye-able pair of glasses. It will show as brown by default, simply dye the item or apply color to it via commands. If you use Model Engine on your server: I have included potion.json file to use instead of horse armor (and use your standard item plugins to equip them), this way you don’t have to mess with the Model Engine files.
