I have a file that is 32 x 16 pixel with two textures in it. I want to specify that the texture is from pixel 17 to pixel 32. Is this possible, and if so how?

 

This is my current code:

public static void registerItemRenderer(){
        registerItemModel(InitItems.berylloniteGem);
    }

    public static void init(Item item, int meta){
        RenderItem renderItem = Minecraft.getMinecraft().getRenderItem();
        renderItem.getItemModelMesher().register(item, meta, new ModelResourceLocation(item.getUnlocalizedName().substring(5), "inventory"));
    }

You need a custom TextureAtlastSprite. I do not recommend.

Why can you not split it into two 16x16 files?

Because I have a lot of items that change texture depending on the metadata. I figured it would be a lot cleaner to have it this way then to have 17 different image files.

So how would I do this?

 

EDIT: Also, why do you not recommend it?

Locate the class, TextureAtlasCompass if I recall the class name correctly.  It's how vanilla renders the compass texture (there's also one for the clock).

 

This should be sufficient information necessary to display the correct portion of your texture file.  The reason I don't recommend it, however, is that if things go south (crashes, bugs, etc) it is very hard to diagnose as the stack trace will not contain this custom class (it will be elsewhere and merely calling properties of said class).  For a two-state texture file you're probably fine.

 

Note:

I am presuming that these classes still exist for 1.9 based on my knowledge of 1.7.10 and what I know about the changes made to the rendering engine: that is, I assume that there is still a class that interprets a multi-frame texture file for the clock and compass, rather than as an animation.

You can put all the textures relating to an object in their own folder (I do this for complex models)
