I made a translucent block but when I placed it down it made the block below it transparent;

Here it is |

              V

Here's the block class -> https://pastebin.com/5A4HnBAx

 

    @Override
    public boolean isOpaqueCube(IBlockState state) {
        return false;
    }

    @Override
    public boolean isFullCube(IBlockState state) {
        return false;
    }

Alot is better than you at everything

I had odd looking rendering for translucent objects for which the above was not sufficient.  As I recall the translucent material (glass in my case) appeared opaque and nothing was seen through it.

 

    @Override
    public BlockRenderLayer getBlockLayer() 
    {
        return BlockRenderLayer.TRANSLUCENT;
    }

Yes, the original poster had that function overridden and returning the proper value already.
