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

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"} } } ] }

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.
