I've heard that you can use independent transform values with two different models using IModel. Is that true? Can someone explain to me what an IModel is, what it does, and why it differs from IBakedModel? Also, can you use IBakedModel with an IModel? How do you register the IModel? Much appreciated, thanks.

I think it is an implementation of forge for baking IBakedModel.

You can use ResourceLocation to get textures as TextureAtlasSprite,

Also there is IModelState and IModelPart which is helpful to make part of a model have independent transform values.

 

So, of course you can use IBakedModel with an IModel, since IModel just returns IBakedModel on #bake method.

So how would I use it? How do I register this to my item?

First, you should make your own ICustomModelLoader, and register that into ModelLoaderRegistry.

In ICustomModelLoader you should check if a resourceLocation of a model is acceptable,

and loads the model from the resource location.
