//assets/minecraft/models/block/cube.json

{
    "parent": "block/block",
    "elements": [
        {   "from": [ 0, 0, 0 ],
            "light_emission":15,
            "to": [ 16, 16, 16 ],
            "faces": {
                "down":  { "texture": "#down", "cullface": "down" },
                "up":    { "texture": "#up", "cullface": "up" },
