What Are Chunks In Minecraft?
Chunks are a 16×16 block area which also includes the 256 blocks underneath each surface block that is found on the Y-axis corresponding to this area. It totals 65,536 blocks and is loaded as soon as you enter its vicinity. As you move through your Minecraft world, chunks get loaded on the basis of the direction you walk in.
Why Do Chunks Become Buggy?
Minecraft chunks are constantly getting rendered and de-rendered at every turn during your playtime. You might see the horizon disappear behind you and assume that’s because it is outside your field of view. But that’s not the case. Once a chunk is outside your draw distance, it gets de-rendered. In the same way, chunks get rendered once they enter your draw distance.
Due to this constant influx and efflux of chunks, the assets can sometimes become buggy and unstable. This is why it is advisable to reload chunks when you face problems in your game.
How To Reload Chunks?
In the Java version, things become a lot simpler. You can obviously quit your current session and log into your server again. This will reload Minecraft chunks. But the JE offers a solution that does not require you to quit your game. You can hold down the F3 key and then press the A key.
You will know whether this works when you see the game reload visible chunks all around you. Depending on the specifications of your computer, it may take some time for this process to be completed. Remember, it only works in the JE and nowhere else.
Some More Useful F3 Commands:
Pressing F3 only in Java pulls up the debug screen. There are other functions you call up by clicking F3 along with the keys mentioned below –
- S to reload all resources from the web
- T to reload textures
- D to clear your chat history
- F to increase draw/render distance
- P to turn auto-pause on and off when another window is open
- H to turn detailed item descriptions on and off
- B to toggle mob hitboxes
- G to turn chunk borders in the world on and off
- N to switch between being a Creator and a Spectator
- I to copy block and entity data to the clipboard
- ESC to pause your game without bringing up the menu
How To Reset Chunks?
Your world will not stay the same after resetting aka regenerating. That’s right — you will lose all your progress including your cool farm buildings, houses, castles and what not. So keep that in mind before you try this.
Now why would you need to hit the reset button? Sometimes, when your world becomes too large, game performance may take a hit. In instances like this, a temporary solution would be to delete an active chunk or two from your world to alleviate the performance lag.
As long as you have a computer, you should be able to reset chunks within your Minecraft world. Before doing this, it is advisable to create a back-up of your game world. It can be found in the “.minecraft” folder under the “%appdata%” file. Just hit Run and search for “%appdata%”. To know how to create a back-up in detail, check out these helpful articles on it by Mojang.
Once you download it, select File and then Open Region. Next, you need to navigate the location of your world’s folder under AppData. The entirety of your Minecraft world is nestled under the region folder. When you open a segment of your world, you will see a grid representation of it in the MCA Selector app.
Each square in this grid is a chunk in your world. Selecting the squares turns it orange. You can select all the chunks you want to edit out of your game and then hit the reset button. To do this, click on the Selection menu item and then hit Delete Selected Chunks. This will turn the grids you have selected black in color, which denotes deletion of the chunks corresponding to the grids.
Once you’ve done that, you can load into your world and find that the chunks have been reset into their original states.
For the Minecraft Bedrock edition on PC, you’ll need to use a different third-party app called Amulet. And the process here is a bit different from what we’ve explained for the MCA Selector. You can learn how to use Amulet by checking out the above video.
How To See Chunk Borders?
In the Minecraft Java Edition, you can hold down F3 and press G on your keyboard to bring up the chunk grid. The chunk grid in the game is represented by a multi-colored wireframe that moves when you transition from one chunk to another.
This wireframe will only appear in the chunk that you’re currently standing on and when you move to a different one, the multi-colored grid frame then shows the boundaries of that specific chunk in the game. To disable this feature, hold down F3 and press G again. To properly see the actual size of the chunk, go higher in creative mode and then look down. You’ll get an accurate idea of how big a chunk really is.
Wrapping Up
Reloading and resetting chunks have entirely different consequences. Resetting will delete chunks and anything you’ve built on them. There is no way to bring a deleted chunk back unless you’ve already backed up your world folder which we advise you to do before using the MCA Selector or the Amulet tool. When you experience a problem with your game world, always reload first. Only use the reset option to regenerate chunks if reloading chunks doesn’t work.
