I was updating my custom trees today and I finished the wood, but when I got to the leaves and I place them down...all the transparent parts on the texture are black in the game. Does anybody have any ideas why updating my leaves to 1.8 does this and how to fix it? Here is my class:

 

public class ExampleLeaves extends BlockLeaves implements IShearable{

private final String name = "ExampleLeaves";
protected boolean isTransparent;

public ExampleLeaves(int id) {
	super();
	this.setUnlocalizedName(Mod.modid + ":" + name);
	this.setCreativeTab(Mod.ModTab);
}

public String getName(){
	return name;
}

@Override
public int getRenderColor(IBlockState state){
	return ColorizerFoliage.getFoliageColorBasic();
}

 @SideOnly(Side.CLIENT)
    public int colorMultiplier(IBlockAccess worldIn, BlockPos pos, int renderPass)
    {
        return BiomeColorHelper.getFoliageColorAtPos(worldIn, pos);
    }

@Override
    public int getBlockColor()
    {
        return ColorizerFoliage.getFoliageColor(0.5D, 1.0D);
    }

@Override
    public boolean isLeaves(IBlockAccess world, BlockPos pos)
    {
        return true;
    }

@Override
    public boolean isShearable(ItemStack item, IBlockAccess world, BlockPos pos)
    {
        return true;
    }

@Override
public List<ItemStack> onSheared(ItemStack item, IBlockAccess world, BlockPos pos, int fortune) {
	return new java.util.ArrayList(java.util.Arrays.asList(new ItemStack(this, 1, 1)));
}

@Override
public EnumType getWoodType(int meta) {
	return null;
}

 public boolean isOpaqueCube()
    {
        return !this.fancyGraphics;
    }

    @SideOnly(Side.CLIENT)
    public void setGraphicsLevel(boolean fancy)
    {
        this.isTransparent = fancy;
        this.fancyGraphics = fancy;
        this.iconIndex = fancy ? 0 : 1;
    }

    @SideOnly(Side.CLIENT)
    public EnumWorldBlockLayer getBlockLayer()
    {
        return this.isTransparent ? EnumWorldBlockLayer.CUTOUT_MIPPED : EnumWorldBlockLayer.SOLID;
    }

    public boolean isVisuallyOpaque()
    {
        return false;
    }
}

Your setGraphicsLevel does not get called, ever, because Minecraft calls it from the direct instance of the vanilla leaves.

 

What you have to do is every time you use

fancyGraphics

, call

!Blocks#leaves#isOpaqueCube()
