Frostbyte's Item Model Modifier

A command takes the item held in the main hand and sets, reads or resets its model. Running it with one of four arguments either applies a chosen model, returns the identifier of the model currently applied, opens the browsing screen, or restores the item to its vanilla model. A model stays on the item as data stored with it, so the custom model still renders after the mod is removed, and stacks only merge with items carrying the same data.

The browsing screen shows two item slots at the top: the current held item on the left and a preview on the right. Below them, a searchable, scrollable list shows every loaded item model in alphabetical order by identifier. Clicking a model updates the preview, and a green check mark button in the center applies the selection before the screen closes. A red X on the right exits without applying anything, while a blue arrow on the left clears the held item back to its default look. An item given a new model in the helmet slot renders that model instead of the helmet texture.
