How to Use the FillBiome Command in Minecraft

This Minecraft tutorial explains how to use the /fillbiome command with screenshots and step-by-step instructions.

You can fill a region with a particular biome using the /fillbiome command in Minecraft. This command is useful for customizing an area in your Minecraft work by changing the weather, the sky color or the grass color, but it doesn't actually change any of the blocks in the fill region. Let's explore how to use this cheat (game command).

Java

FillBiome Command in Minecraft Java Edition (PC/Mac)

In Minecraft Java Edition (PC/Mac), there are 2 syntaxes for the /fillbiome command.

To fill a region with a biome:

/fillbiome <from> <to> <biome>

To fill a region with a biome based on a filter:

/fillbiome <from> <to> <biome> replace <filter>

Definitions

from is the starting x y z coordinate for the fill region (ie: first corner block).
to is the ending x y z coordinate for the fill region (ie: opposite corner block).
biome is the Minecraft ID of the biome that you wish to fill the region with. (See List of Biome IDs.)
filter is the Minecraft ID of the biome that you wish to replace. This is only used when you want to replace one specific biome in a fill region with another biome.

Examples

Java

Example in Java Edition (PC/Mac)

To fill a region with the Grove biome:

/fillbiome ~ ~ ~ ~10 ~10 ~10 grove

To fill a region with the Nether Wastes biome:

/fillbiome ~-10 ~-10 ~-10 ~10 ~10 ~10 nether_wastes

To fill a region with the Jungle biome:

/fillbiome ~-10 ~-10 ~-10 ~10 ~10 ~10 jungle

How to Enter the Command

1. Open the Chat Window

The easiest way to run a command in Minecraft is within the chat window. The game control to open the chat window depends on the version of Minecraft:

For Java Edition (PC/Mac), press the T key to open the chat window.

2. Type the Command

In this example, we are going to fill a region with the Grove biome in Minecraft Java Edition (PC/Mac) with the following command:

/fillbiome ~ ~ ~ ~10 ~10 ~10 grove

Type the command in the chat window. As you are typing, you will see the command appear in the lower left corner of the game window. Press the Enter key to run the command.

Once the cheat has been entered, the biome associated with the fill region will change and be set to the Grove biome.

You will see the message "36 biome entries set between -12, 72, -204 and 0, 80, -196" appear in the lower left corner of the game window to indicate that the fillbiome command has completed.

Now, the fill region will take on the new properties of the Grove biome. In this example, it will now snow in this Desert (just like the Grove biome) and snow will accumulate on the ground. This phenomenon will only happen in the fill region.
