====== Manipulating a Block's appearance (1.14) ======
//This is the 1.14 version of this tutorial. For the latest version, see [[tutorial:blockappearance|Manipulating a Block's appearance]].//

===== Making a block transparent =====
You may have noticed that even if your block's texture is transparent, it still looks opaque.
To fix this, override ''getRenderLayer'' and return ''BlockRenderLayer.TRANSLUCENT'':
<code java>
class MyBlock extends Block {
    @Environment(EnvType.CLIENT)
    @Override
    public BlockRenderLayer getRenderLayer() {
        return BlockRenderLayer.TRANSLUCENT;
    }

    [...]
}

</code>

You probably also want to make your block transparent. To do that, use the ''Material'' constructor to set ''blocksLight'' to false.
<code java>
class MyBlock extends Block {
     private static final Material MY_MATERIAL = new Material(
            MaterialColor.AIR, // materialColor,
            false, // isLiquid,
            false, // isSolid,
            true, // blocksMovement,
            false, // blocksLight,  <----- Important part, the other parts change as you wish
            true, // !requiresTool,
            false, // burnable,
            false, // replaceable,
            PistonBehavior.NORMAL // pistonBehavior
    );

    public MyBlock() {
        super(Settings.of(MY_MATERIAL));
    }

    [...]
}

</code>

===== Making a block invisible =====
First we need to make the block appear invisible.
To do this we override ''getRenderType'' in our block class and return ''BlockRenderType.INVISIBLE'':
<code java>
    @Override
    public BlockRenderType getRenderType(BlockState blockState) {
        return BlockRenderType.INVISIBLE;
    }
</code>
We then need to make our block unselectable by making its outline shape be non-existent.
So override ''getOutlineShape'' and return an empty ''VoxelShape'':
<code java>
    @Override
    public VoxelShape getOutlineShape(BlockState blockState, BlockView blockView, BlockPos blockPos, EntityContext entityContext) {
       return VoxelShapes.empty;
    }
