Hello, do the thing which you can change in the game(creates a new stack and change certain data). I want to do to you during the game to replace the path to textures/models without rejoining the game. Earlier in 1.7 this can be done using the IItemRenderer, but now I don't see a solution.

 

Code 1.7 - icon:

@SideOnly(Side.CLIENT)
public final class IconRenderer implements IItemRenderer
{
    public static final IconRenderer INSTANCE = new IconRenderer();

    @Override
    public boolean handleRenderType(final ItemStack item, final ItemRenderType type)
    {
        return type == ItemRenderType.EQUIPPED || type == ItemRenderType.EQUIPPED_FIRST_PERSON;
    }

    @Override
    public boolean shouldUseRenderHelper(final ItemRenderType type, final ItemStack item, final ItemRendererHelper helper)
    {
        return false;
    }

    @Override
    public void renderItem(final ItemRenderType type, final ItemStack stack, final Object... data)
    {
        GL11.glPushMatrix();
        final Tessellator tess = Tessellator.instance;
        final EntityLivingBase entityliving = (EntityLivingBase) data[1];
        final IIcon icon = entityliving.getItemIcon(stack, 0);
        final float tickness = 0.0625F;

        ItemRenderer.renderItemIn2D(tess, icon.getMaxU(), icon.getMinV(), icon.getMinU(), icon.getMaxV(), icon.getIconWidth(), icon.getIconHeight(), tickness);
        GL11.glPopMatrix();
    }
}

How is this done?

You can do it the same way as a resourcepack would.

And even if NBT will indicate a new path to textures?
