First of all I am new to modding (started a few days ago) tough I know C, C# and the basics of Java (though is very similar to C#).

I am trying to make a custom Geode, a jade geode. I managed to create a CaveFeature, CavePlacement for the geode, and it is being correctly generated. 

At the time all my blocks states and models are registered with simpleBlock() in my BlockStateProvider class. Example:

simpleBlock(RiftBlocks.JADE_BLOCK.get());

[Rift being my mods name and RiftBlocks where I store my mods blocks]

The problem is, when I use simpleBlock with my jade cluster png, obviously, it doesnt work.

How could I make my jade cluster model look as intended?

if you did any model registration in code, delete that. just register the block itself.

in /resources/assets/your_mod_id/blockstates directory should be a file  your_block_as_named_in_code.json .
in /resources/assets/your_mod_id/models/block directory should be a file  your_model_as_named_in_above_file.json .

see vanilla oak saplings in minecraft jar.

The thing is, I rather do it in code and generate the json data than create the json by hand.

Okey so I solved my problem doing this:

simpleBlock(RiftBlocks.JADE_CLUSTER.get(), cross(RiftBlocks.JADE_CLUSTER.get()));

And adding this functions in my class:

public ModelFile cross(Block block)
    {
        return models().cross(name(block), blockTexture(block));
    }

private String name(Block block) {
	return block.getRegistryName().getPath();
}

Now my problem is the transparency not working...

Have you set the RenderType to cutout ?

Thanks, its fixed now.

Though I am now struggling to make the jade clusters rotate... any solutions? I know it has to be like amethyst clusters blockstates:

{
  "variants": {
    "facing=down": {
      "model": "minecraft:block/amethyst_cluster",
      "x": 180
    },
    "facing=east": {
      "model": "minecraft:block/amethyst_cluster",
      "x": 90,
      "y": 90
    },
    "facing=north": {
      "model": "minecraft:block/amethyst_cluster",
      "x": 90
    },
    "facing=south": {
      "model": "minecraft:block/amethyst_cluster",
      "x": 90,
      "y": 180
    },
    "facing=up": {
      "model": "minecraft:block/amethyst_cluster"
    },
    "facing=west": {
      "model": "minecraft:block/amethyst_cluster",
      "x": 90,
      "y": 270
    }
  }
}

But how do I achieve this in code?

Also, sorry for being a noob.

Solved: 

protected void registerStatesAndModels()
{
    directionalCross(RiftBlocks.JADE_CLUSTER);
    directionalCross(RiftBlocks.SMALL_JADE_BUD);
    directionalCross(RiftBlocks.MEDIUM_JADE_BUD);
    directionalCross(RiftBlocks.LARGE_JADE_BUD);
    simpleBlock(RiftBlocks.COMPACT_COAL_ORE);
    simpleBlock(RiftBlocks.JADE_BLOCK);
    simpleBlock(RiftBlocks.BUDDING_JADE);
}

private String name(Block block) {
  	return block.getRegistryName().getPath();
}

private void directionalCross(RegistryObject<Block> block)
{
  	directionalBlock(block.get(), models().cross(name(block.get()), modLoc("block/" + name(block.get()))));
}

private void simpleBlock(RegistryObject<Block> block)
{
  	simpleBlock(block.get());
}
