What is wrong with using a Void Generator Plugin?

I have often encountered the problem of corrupted worlds when using a Void Generator Plugin.
In case the world is transferred between servers or loaded in single player where the generator plugin is not available, Vanilla will pick up chunk generation where the generator cut off.
This causes the typical world corruption look many people are familiar with, a giant void surrounded by land.

Another issue that bugs me is, most void generator plugins don't override the biome to be minecraft:the_void, nor spawn a proper start platform, or even set no spawn point, resulting you in plummeting to your death as soon as you enter the world.

But I can just ensure the plugin is always available.

While that is a valid point, it is not always possible or practical.
When sharing worlds with others, you might not always have control over the plugin availability.
Also, imagine the plugin fails to load or gets disabled for some reason.
Then you are left with a corrupted world and no simple way to fix it.

Furthermore, some Void Generator Plugins might not be compatible with all Minecraft servers or versions.

The Solution?

Just use vanilla Minecraft! No plugins required, forward compatible, and works everywhere.

Vanilla offers so-called Flat world presets.
These presets allow you to create a world with a custom flat terrain.
You might be most familiar with the Classic Flat preset.

The Void preset has been around since Minecraft 1.9 (specifically 15w37a), so almost a decade.

It spawns a proper start platform, making it easier to build on, and only consists of the minecraft:the_void biome, resulting in a less frustrating experience when first entering the world.

How do I create a Void world on my server without a void generator?

World management plugins

You are probably already using one, and most serious world management plugins support creating worlds with custom presets (also known as "generator settings").

Our plugin Worlds, allows you to use presets without any hassle.

/world create "My void world" preset the-void

With plugins like Multiverse-Core this might be a little more complicated, but still possible.

/mv create my_void_world normal --world-type flat --generator-settings {"biome":"minecraft:the_void","layers":[]}

Vanilla Minecraft settings

If you don't have, or want to use, a world management plugin, you can use the generator settings directly inside the server.properties file.

generator-settings={"biome"\:"minecraft\:the_void","layers"\:[]}
level-type=minecraft\:flat

Singleplayer

In Singleplayer, you can also select the Void preset from the world creation screen when creating a new Superflat world, by clicking the "Customize" button, selecting "Presets", choosing "The Void" and then "Use Preset" and "Done".

You can also just upload singleplayer worlds to your server and every generator setting will be respected.
