Applying different textures to different faces of elements of block model

[plain dawn]

Hello, I'm trying to model a lever in Blockbench. A model consisting of two elements. Where one element is purely cobblestone, then on the second element, I need to define different textures for north, south, east, west, up, down respectively.

The only example I've seen is something like this:

"minecraft:material_instances": {
    "*": {
        "texture": "template_bark",
        "render_method": "opaque"
    },
    "up": {
        "texture": "template_tops",
        "render_method": "opaque"
    },
    "down": {
        "texture": "template_tops",
        "render_method": "opaque"
    }
}

But this only works for a single element. How can I apply textures with more fine grained control?

You need to set a material instance to a bone in blockbench to have more control

now you can set the bone texture with

    "*": {
        "texture": "template_bark",
        "render_method": "opaque"
    },
    "up": {
        "texture": "template_tops",
        "render_method": "opaque"
    },
    "down": {
        "texture": "template_tops",
        "render_method": "opaque"
    },
    "fire": {
        "texture": "template_tops",
        "render_method": "opaque"
    }
}```
