Exclude default UVs for Minecraft model faces

[ChloeDawn]

If the UVs are the default for a face in a Minecraft model (relative to world coordinates), they could be excluded from the export, as the game infers these when the models are baked, and therefore explicit declaration in the JSON is not necessary. For example, see vanilla's cube.json:

Code: Select all

{
    "parent": "block/block",
    "elements": [
        {   "from": [ 0, 0, 0 ],
            "to": [ 16, 16, 16 ],
            "faces": {
                "down":  { "texture": "#down", "cullface": "down" },
                "up":    { "texture": "#up", "cullface": "up" },
                "north": { "texture": "#north", "cullface": "north" },
                "south": { "texture": "#south", "cullface": "south" },
                "west":  { "texture": "#west", "cullface": "west" },
                "east":  { "texture": "#east", "cullface": "east" }
            }
        }
    ]
}
