[1.9.4]Registration JSON model

[Hundred Layers]

  Hi, I have a problem with registration JSON model for the block.

The fact is that if I use as a name for the model registerName everything is working properly.

public static void registerRender(Block block) {
        Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(Item.getItemFromBlock(block), 0, new ModelResourceLocation(block.getRegistryName(), "inventory"));
    }

But if I try to set the file name alone is my model is not displayed.

public static void registerRenderSuper(Block block, int meta, String file) {
        Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(Item.getItemFromBlock(block), meta, new ModelResourceLocation("elderutilities:" + file, "inventory"));
    }

P.s Under the model I have in mind: blockstates, models block and item.

1) Why aren't you using the registry name?

2) What is the value of "file"?

3) What is the block's registry name?

1) The fact that different units shall be of the same model. I do not want to duplicate them.

2) Name the file with the model json.
