Snow! Real Magic! ⛄ (Fabric)

Two game rules, `snowrealmagic:blizzardStrength` (1–8, max layers) and `snowrealmagic:blizzardFrequency` (N/10000 per tick per chunk), make snow blocks fall from the sky. Have fun!

Datapacks can change which blocks interact with snow by adding to the mod’s block tags. To append entries, create the file under the `snowrealmagic` namespace in your datapack, e.g. `data/snowrealmagic/tags/block/containables.json`:

(Also see [Editing tags using KubeJS](https://kubejs.com/wiki/tutorials/tags))

{
    "values": [
        "mymod:my_flower",
        {
            "id": "#mymod:my_pebbles",
            "required": false
        }
    ]
}

Available tags:

– **containables**: Blocks that snow can be placed into, turning them snow-covered. (Default: `plants`, `offset_y`, `expand_model` and `#c:chains`)
– **not_containables**: Blacklist. Blocks here can never contain snow, even if they are in `containables`. (Default: `#minecraft:leaves`)
– **plants**: Plants that become snowy plants when snow covers them. Compared to #containables, it will be able to be detected by shaderpacks to make them swing, but as far as I know, no shaderpacks support this yet. (Default: dead bush, flowers, saplings, mushrooms, etc.)
– **entity_inside**: Snow-covered blocks that keep their touch effects, e.g. wither rose damage. (Default: wither rose, sweet berry bush)
– **animate_tick**: Snow-covered blocks that keep their ambient particles, e.g. firefly bush. (Default: wither rose, open eyeblossom, dry grass, firefly bush)
– **offset_y**: Flat blocks that are rendered slightly raised when snow-covered, to avoid z-fighting with the snow layer. (Default: pebbles, twigs and similar decorations from supported mods)
– **expand_model**: Blocks whose model should be treated as a full cube when snow-covered. Used for compat with mods like vertical slabs.
– **cannot_accumulate_on**: Snow will not naturally accumulate on top of these blocks. (Default: hay block, slabs)

Resource packs can change how a block looks when it is snow-covered. Add a `.json.mcmeta` file next to the block’s **model** file with an `srm` section pointing to the model to use instead. For example, `assets/minecraft/models/block/dandelion.json.mcmeta`:

{
    "srm": {
        "model": "mypack:block/snowy_dandelion"
    }
}

The snowy model is a regular block model. For cross-shaped foliage you can parent the built-in template, which renders the plant together with a snow overlay:

{
    "parent": "snowrealmagic:block/snowy_cross",
    "textures": {
        "cross": "block/dandelion",
        "snow": "mypack:block/snowy_dandelion"
    }
}

For double-height plants such as tall grass, put the mcmeta on the top-half model and add an `overrideBlocks` list with the block ID, so the upper half also renders snowy:

{
    "srm": {
        "model": "mypack:block/snowy_tall_grass_top",
        "overrideBlocks": ["minecraft:tall_grass"]
    }
}

This feature requires the client config `snowVariants` to be enabled (it is by default).
