This code works perfectly:

 

 

private static void load_texture(ItemCA item)

    {

        Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, new ModelResourceLocation(item.getUnlocalizedName().substring(5), "inventory"));

        LogHelper.info("Loading model in '"+item.getUnlocalizedName().substring(5)+"'");

    }

 

 

 

However when I overload this method to handle items with metadata they're rendered as cubes (json model file not loading)

 

 

private static void load_texture(ItemCA item, int metastart, int metaend)

    {

        for(int i=metastart;i<=metaend;i++)

        {

            Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, i, new ModelResourceLocation(item.getUnlocalizedName(new ItemStack(item, 1, i)).substring(5), "inventory"));

            LogHelper.info("Loading model in '" + item.getUnlocalizedName(new ItemStack(item, 1, i)).substring(5) + "' for metadata "+i);

        }

    }

 

 

 

Since the first one is working, assets is loading properly etc.

 

The part of log with all the "Loading model..."

[17:09:49] [Client thread/INFO] [Coal Age]: Loading model in 'coalage:colored_coal_black' for metadata 15

 

 

 

I'd think that if "coalage:coal_piece" is OK, then "coalage:colored_coal_black" hould work, but it doesn't.

And getUnlocalizedName method is overloaded and works as I want it to. That's proved by the log

Hi

 

This link might be useful

I think your problem is that you need ModelBakery.

 

-TGG

You also need to register all of your item variants to ModelBakery.addVariantName(yourItem, String[]{variant1, variant2, etc.}). Each variant should be the model name qualified by your mod id, e.g. 'yourmodid:your_item_variant_1'.

The ModelBakery.addVariants works great

 

However to load the models I had to use this method:

 

 

for(int i=metastart;i<=metaend;i++)

        {

            Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, i, new ModelResourceLocation(item.getUnlocalizedName(new ItemStack(item, 1, i)).substring(5), "inventory"));

        }

 

 

 

Because the one I fount to be said correct:

 

 

Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item,

                    new ItemMeshDefinition()

                    {

                        public ModelResourceLocation getModelLocation(ItemStack stack)

                        {

                            return new ModelResourceLocation(item.getUnlocalizedName(stack).substring(5), "inventory");

                        }

                    });

 

 

was being called all the time and made a giant mess in the log

yeah, that's how it is supposed to work, it's a technique called a 'function object'.  Every time minecraft wants to know what ModelResourceLocation to use for your itemstack, it calls the getModelLocation() you have given it.  So if you put a println in there, it will print every time it's called, which is a lot.  The solution is not to put a println in there.  Or, adding every single variant (like you have done) works too, since there aren't very many.
