Creating Item Models

To make your model use an .obj file, add it to the model parameter:

{
  "parent": "minecraft:block/block",
  "model": "myron:block/crystal_ore_item",
  "gui_light": "side"
}

Item models support parents, making the transformation for block models very easy. If you do need to specify your own transformations, you can do that too:

{
  "model": "myron:misc/torus",
  "gui_light": "side",
  "display": {
    "gui": {
      "rotation": [ 130, 100, 80 ],
      "translation": [ -0.5, 0, -0.5],
      "scale":[ 0.5, 0.5, 0.5 ]
    },
    "ground": {
      "rotation": [ 0, 0, 0 ],
      "translation": [ 0, -1, 0],
      "scale":[ 0.25, 0.25, 0.25 ]
    },
    "fixed": {
      "rotation": [ 0, 0, 0 ],
      "translation": [ 0, 0, 0],
      "scale":[ 0.5, 0.5, 0.5 ]
    },
    "thirdperson_righthand": {
      "rotation": [ 75, 45, 0 ],
      "translation": [ 0, 2.5, 0],
      "scale": [ 0.375, 0.375, 0.375 ]
    },
    "firstperson_righthand": {
      "rotation": [ 0, 45, 0 ],
      "translation": [ 0, 0, 0 ],
      "scale": [ 0.40, 0.40, 0.40 ]
    },
    "firstperson_lefthand": {
      "rotation": [ 0, 225, 0 ],
      "translation": [ 0, 0, 0 ],
      "scale": [ 0.40, 0.40, 0.40 ]
    }
  }
}
