# Technical Notes for the texture pack implementation Relevant classes: `ItemModelManager` can be used to select an `ItemModel`. This is done from the `ITEM_MODEL` component which is defaulted by the `Item` class. The list of available `ItemModel`s (as in `Identifier` -> `ItemModel` maps) is loaded by `BakedModelManager`. To this end, item models in particular are loaded from `ItemAssetsLoader#load`. Those `ItemAssets` are found in `assets//items/` directly (not in the model folder) and can be used to select other models, similar to how predicates used to work
