Install in the game only; not needed on the server
CustomModelDataViewer is a lightweight mod that adds a dedicated creative tab for all items using the new 1.21.4+ CustomModelDataComponent. It automatically detects any items referencing a customModelData string (like in the example .json snippet) and organizes them in one convenient location. This makes it easier for resource pack creators and modders to quickly review, test, and manage custom item models without searching through standard tabs or multiple files.
Example Item:
assets/minecraft/items/brown_dye.json
{
"model": {
"type": "minecraft:select",
"property": "minecraft:custom_model_data",
"cases": [
{
"when": "old_hat",
"model": {
"type": "minecraft:model",
"model": "skyrealm:item/hats/old_hat",
"tints": [
{
"type": "minecraft:custom_model_data",
"default": 15702017
}
]
}
}
],
"fallback": {
"type": "minecraft:model",
"model": "minecraft:item/brown_dye"
}
}
