What?? I was saying that resource location exists to prevent issues like this. If you don’t have anything special (Transformations / 3D models) for your time you should probably auto generate the models.
I’ve gone all the way down this path and don’t recommend it. Vanilla does it with all models in a single folder and that’s the easiest way to do it.
The only way to do it is with JSON.
for(Item item : allModItems) ModelLoader.setCustomModelResourceLocation(item, 0, new ModelResourceLocation( item.getRegistryName(), “normal”));
