Minecraft’s world is made entirely of chunks, stretching in all directions as far as your eyes can see (or your render distance setting can allow). Therefore, it would stand to reason that these chunks can sometimes become bugged and not load properly for your game. You may even want these chunks cleared of all player-made modifications and reverted to their original state.
What are Chunks in Minecraft?
Chunks are clusters of blocks that act as the basis for your Minecraft world. They take up a space of 16 by 16 blocks horizontally and 256 blocks vertically. This gives them a total size of 65,536 blocks.
Chunks are loaded every time you boot up your Minecraft world. Moreover, depending on your render distance, only the chunks in a certain vicinity are loaded at any given time. Additional chunks are loaded in as your player traverses the world.
How to Reload Chunks in Minecraft
The game dynamically renders and de-renders chunks throughout your playtime. It is, therefore, possible for one or a few of the chunks to become glitched. This means that they do not load properly or are not displayed properly at your end. In such a situation, you may have to reload or ‘refresh’ the chunks in your Minecraft world and force them to be rendered again.
Thankfully, a simple keyboard shortcut on the Minecraft Java edition can get this done. Hold down the F3 key and press A. You will now see your Minecraft world being reloaded in chunks around you.
This may take a few seconds, depending on your system’s specifications, but once it’s done, any glitches or errors you may have had in the chunk rendering previously should be rectified.
The aforementioned method is useful for reloading chunks in a single-player and on any online server. However, if you’re on the Minecraft Bedrock edition, you won’t be able to use this shortcut. Your best bet will be to exit and re-enter the world or rejoin the server.

How to Reset Chunks in Minecraft
Sometimes, you may want to have certain parts of your Minecraft world completely reset so you can start afresh. This can be desirable if your world has become too big and laggy or if the file size has become too much for your system storage. Otherwise, maybe there’s a new update on the way, and you simply want those beautiful new biomes closer to your house. In a situation such as this, your best bet is to reset some chunks in your Minecraft world completely.
- Do note that unlike reloading chunks, which only load up the same chunk from memory, resetting chunks in Minecraft will completely clear any player-made modifications within those chunks.
- Then, once you load up the world again, chunks will be reverted to their original state.
- This also means that resetting chunks where no modifications were made will not have any effect.
- It is also important to make a backup of your world folder before making any changes to it since the changes are irreversible.
Here’s what you should do if you’re playing the Java edition of Minecraft on PC:
Installing the software
You will first install the software that you need to use for resetting chunks in Minecraft Java. This software is the MCA Selector. To download this, go to this site. Scroll down to the Download and Installation section, download the latest version, and install it.
Making a backup
Your next task will be to safely create a backup of your game world. This is especially important here because MCA Selector will delete chunks from your Minecraft world in real-time, so any mistakes cannot be reverted easily.
- First, open up your start menu and type %appdata% in the search bar to find your game world folder.
- Then go to the .minecraft folder and open saves.
- After that, find the folder with your world name, copy it and store it in some other location. Now you have a backup, and if you accidentally mess up while resetting your Minecraft chunks, you can copy this folder back and overwrite your edited world folder.
Opening the world in the software
- Now start up MCA Selector. Here, you will see a black screen with a grid. To load in your Minecraft world so that you can reset the chunks, click on File and then on Open Region.
- Navigate to the path Drive C > Users > [user name] > AppData > Roaming > .minecraft > saves > [world name].
- Note: If the AppData folder is not visible, you may have to enable your settings to view hidden files and folders.
- The next step is to open the folder corresponding to the Minecraft world you want to edit.
- Main game: open region.
- The Nether: open DIM-1.
- The End: open DIM1.
You should now see the world start to load in. It will take some time for it to load in entirely, but you can start working while it continues to load the outer regions.
Selecting chunks to reset
The smaller grids you see will represent the individual chunks in your Minecraft world. From this screen, you can select those that you want to reset. These selected chunks become highlighted as orange.
If you zoom out enough, you should a larger grid, where you can select blocks to reset larger spaces of your Minecraft world.
If you want to select which areas to keep instead of which areas to reset, you can simply select the areas that you want to stay unaltered in your world, and then go to Selection and select Invert. Doing so will unselect the chunks you want to preserve, and select all other chunks that need to be reset.
You can also select the chunks based on the time you’ve spent playing in them by going to Tools, selecting Filter chunks and using the Inhabited time filter.
Resetting the chunks
Once you’ve selected the parts you want to delete, simply go to Selection and click on Delete selected chunks.
The deleted areas will now become black or grey, and the chunks will be reloaded to their original state when you open your Minecraft world again. Note that there is no need to save the file since this tool edits your world in real-time.
Minecraft Bedrock (including Pocket Edition)
Installing the software
For the Minecraft Bedrock edition, I will use a tool called the Amulet Editor. This software can be downloaded here. Once downloaded, follow the installation process.
Finding coordinates of chunks to be reset
To use this tool, you first need to know the rough coordinates of the chunks that you want to reset in your Minecraft world. For this, open your world in-game and turn on the Show Coordinates option in the game settings screen.
Now go to the place you want to reset and note down the coordinates.
Finding the game world folder
Another thing you need to do in-game is to memorize the world icon for the Minecraft world that you want to edit. This will help you in finding your game world folder.
To find the game world folder in Minecraft Pocket Edition, go to your phone’s File Manager and open its internal storage or SD card, depending on where you’ve installed your game. Open the games folder and then open the com.mojang folder. Some phones may have the minecraft folder instead of this. Afterwards, open the minecraftWorlds folder.
To get to the same folder in Minecraft Bedrock edition on PC, open your start menu and search for %USERPROFILE%. Now follow the path AppData > Local > Packages > Microsoft.MinecraftUWP_8wekyb3d8bbwe > LocalState > games > com.mojang > minecraftWorlds.
Here, you will find multiple folders with random alpha-numeric names. These are the folders for your worlds in Minecraft.
To find which world folder belongs to the world that you want to edit, open each folder and check the image named world_icon.jpeg. See which folder contains the image that matches the world icon you previously memorized for your world.
Once you’ve found the correct folder, copy it to another location on your PC. If this folder is on your mobile, you will have to transfer it to your PC through online platforms such as Google Drive or through a USB cable.
Opening the world in the software
Now open up the Amulet Editor by going to the installation folder and clicking on amulet_app.exe.
This will open up a command prompt window as well as a small program window for the Amulet Editor. On this window, click on Open World, and select Open other world.
Now navigate to the location where you saved your game folder, and open it. Your world map should now begin to load in the program. You can move around the map freely as it does use the mouse or the WASD keys.
Selecting chunks to reset
Click on the button in the top right bar that shows your coordinates, and enter the in-game coordinates where you want to reset the chunks. You can shift your view by clicking on the 2D/3D button next to it.
Once this world has loaded, click on the Chunk button in the bottom bar. You can now start selecting the chunks that you want to reset in your Minecraft world by clicking or holding the left mouse button. The selected chunks become highlighted in white.
Resetting the chunks
You can now delete the selected chunks by clicking on Delete Chunks. When you reopen the game afterwards, these chunks will get reset to their original state.
Once you have deleted all the chunks that you wanted to reset, select File and click on Save. Doing so will save the changes to the world folder that you opened.
All you need to do now is to copy the game folder back into the game directory where you copied it from.
You have now successfully reset your chunks from your Minecraft world, and will see them as good as new when you reopen your game!
