Modern Model Format

Allows the use of the 1.21.11 model format in older versions with the help of black magic, specifically allowing all three axis (XYZ) rotation and incrementes larger/smaller than 22.5°, additionally removing the 3x3x3 size constraint.

Example

<details> <summary>Model</summary>

File: assets/minecraft/models/block/diamond_block.json

{
  "format_version": "1.21.11",
  "textures": {
    "all": "block/diamond_block"
  },
  "elements": [
    {
      "from": [0, 0, 0],
      "to": [16, 16, 16],
      "rotation": {"x": 45, "y": 45, "z": 45, "origin": [8, 8, 8]},
      "faces": {
        "north": {"uv": [0, 0, 16, 16], "texture": "#all"},
        "east": {"uv": [0, 0, 16, 16], "texture": "#all"},
        "south": {"uv": [0, 0, 16, 16], "texture": "#all"},
        "west": {"uv": [0, 0, 16, 16], "texture": "#all"},
        "up": {"uv": [0, 0, 16, 16], "texture": "#all"},
        "down": {"uv": [0, 0, 16, 16], "texture": "#all"}
      }
    }
  ]
}

</details>

Supports both rotation types:

All axis rotation

  "rotation": {
    "x": 45,
    "y": 45,
    "z": 45,
    "origin": [
      8,
      8,
      8
    ]
  }

Single axis rotation

  "rotation": {
    "angle": 45,
    "axis": "y",
    "origin": [
      8,
      8,
      8
    ]
  }

Maven

repositories {
  maven { url 'https://jitpack.io' }
}

dependencies {
  modImplementation 'com.github.Nico44YT:ModernModelFormat:<version>'
}

Version generally is comprised of "<mod_version>_<game_version_range>" e.g: "1.3.0-1.19.3-1.21.3"

Issues

If you have found an issue please report it on the github, along with (if applicable):

• any logs
• the model
• a screenshot
• the game version
• modlist

My models are not loading anymore

Try checking the model file for any extra brackets {} because Modern Model Format ensure a strict json validation.
