[1.12.2; Solved] Modelling ItemBlocks with metadata

[Aarilight]

I have a block, "SummonerEmpty" which has variants. They all render correctly in the world, and the ItemBlocks for them seem to function correctly (eg: they place the correct blocks)

However, all the ItemBlocks, when in inventory slots, are the "missing texture", while held they are the "missing texture" block.

This is my currrent block class:

public class SummonerEmpty extends ModBlock {

	public static final IProperty<EndersteelType> VARIANT = PropertyEnum.create("variant", EndersteelType.class);

	public SummonerEmpty() {
		super("summoner_empty", new Material(MapColor.STONE).setTransparent());
		setHasItem();
		setHardness(5F);
		setResistance(30F);
		setHarvestLevel("pickaxe", 1);
		setSoundType(SoundType.METAL);
		setDefaultState(getDefaultState().withProperty(VARIANT, EndersteelType.NORMAL));
	}

	@Override
	protected BlockStateContainer createBlockState() {
		List<IProperty<?>> props = new ArrayList<>(super.createBlockState().getProperties());
		props.add(VARIANT);
		return new BlockStateContainer(this, props.toArray(new IProperty<?>[0]));
	}

	@Override
	public IBlockState getStateFromMeta(int meta) {
		return getDefaultState().withProperty(VARIANT, EndersteelType.byMetadata(meta));
	}

	@Override
	public int getMetaFromState(IBlockState state) {
		return state.getValue(VARIANT).getMeta();
	}

	@Override
	public int damageDropped(IBlockState state) {
		return getMetaFromState(state);
	}

	@Override
	public void getSubBlocks(CreativeTab tab, NonNullList<ItemStack> list) {
		for (EndersteelType enumType : EndersteelType.values()) {
			Logger.info("" + enumType.getMeta());
			list.add(new ItemStack(this, 1, enumType.getMeta()));
		}
	}

	@Override
	public ItemBlock getItemBlock() {
		ItemBlock result = new ItemBlock(this) {
			@Override
			public int getMetadata(int damage) {
				return damage;
			}
		};

		result.setRegistryName(getRegistryName());

		return result;
	}
}

And then models/item/summoner_empty.json:

{
	"parent": "soulus:block/summoner"
}

Which inherits models/block/summoner.json:

{
	"parent": "minecraft:block/cube_all",
	"textures": {
		"all": "soulus:blocks/summoner_normal"
	}
}

I know this wouldn't work for the variants, because it only specifies the normal texture, but I would have expected this to show that texture for all of them, instead of texture erroring... I'm assuming I'm missing something pretty basic for the variants to work?

[solved, this was like 10 billion different issues all rolled into one]

Block models are automatically registered, but item models are not. You need to call ModelLoader.setCustomModelResourceLocation for your item if you want the model to load properly.
