What do you mean with that?
Cause right now I have:
{
"parent": "minecraft:block/block",
"textures": {
"top": "elemental:block/fire_grass_block_top",
"bottom": "elemental:block/fire_dirt_block",
"north": "elemental:block/fire_grass_block_side",
"east": "elemental:block/fire_grass_block_side",
"south": "elemental:block/fire_grass_block_side",
"west": "elemental:block/fire_grass_block_side"
},
"elements": [
{
"from": [0, 0, 0],
"to": [16, 16, 16],
"faces": {
"down": { "uv": [0, 0, 16, 16], "texture": "#bottom", "cullface": "down" },
"up": { "uv": [0, 0, 16, 16], "texture": "#top", "cullface": "up", "tintindex": 0 },
"north": { "uv": [0, 0, 16, 16], "texture": "#side", "cullface": "north" },
"south": { "uv": [0, 0, 16, 16], "texture": "#side", "cullface": "south" },
"west": { "uv": [0, 0, 16, 16], "texture": "#side", "cullface": "west" },
"east": { "uv": [0, 0, 16, 16], "texture": "#side", "cullface": "east" }
}
},
{
"from": [0, 0, 0],
"to": [16, 16, 16],
"faces": {
"north": { "uv": [0, 0, 16, 16], "texture": "#overlay", "tintindex": 0, "cullface": "north" },
"south": { "uv": [0, 0, 16, 16], "texture": "#overlay", "tintindex": 0, "cullface": "south" },
"west": { "uv": [0, 0, 16, 16], "texture": "#overlay", "tintindex": 0, "cullface": "west" },
"east": { "uv": [0, 0, 16, 16], "texture": "#overlay", "tintindex": 0, "cullface": "east" }
}
}
]
}
And only the top and bottom textures work!
