About this Mod
Custom Item Models
Setup
This modification is only needed on the server side - clients without this mod will be able to join and use all provided functionality. It also works in singleplayer if installed on client.
Usage
To see compatible ResourcePack examples, navigate into tutorial directory.
Rename Name Tag on the Anvil into the string that you would usually put inside minecraft:custom_model_data={strings:[]} array.

Diamond before applying Name Tag with the title ruby:
{
count: 1,
Slot: 0b,
id: "minecraft:diamond"
}
Then, apply this Name Tag onto the item via Smithing Table.

Diamond after applying Name Tag with the title ruby:
{
count: 1,
Slot: 0b,
id: "minecraft:diamond",
components: {
"minecraft:custom_model_data": {
strings: ["ruby"]
}
}
}
This mod also changes minecraft:equippable component for such items as armor pieces and elytras.
for example, Diamond Helmet before applying Name Tag with the title crown:
{
count: 1,
Slot: 0b,
id: "minecraft:diamond_helmet"
}

and after applying Name Tag with the title crown:
{
count: 1,
Slot: 0b,
id: "minecraft:diamond_helmet",
components: {
"minecraft:custom_model_data": {
strings: ["crown"]
},
"minecraft:equippable": {
equip_sound: "minecraft:item.armor.equip_diamond",
slot: "head",
asset_id: "cim:crown"
}
}
}

ATTENTION: Be aware that asset_id will always be under cim namespace, due to how vanilla code operates. You can see examples in the tutorial directory.
You don't have to use cim namespace for item models, only for armor rendering.
