How To Clear Unwanted Chunks In Minecraft 1.18/1.19 Java Edition | MCASelector Tutorial
Вставка
- Опубліковано 2 лип 2024
- With each new Minecraft update we have to travel further and further out to find the new additions, but today we're going to solve that problem. Using a tool called MCASelector we can easily, and very precisely, reset parts of our world.
Whether this is to make exploration easier, restore destroyed terrain, or even fix chunk errors, it can all be done with just a few clicks. Even the sprawling worlds of servers can be easily cleaned up without destroying anybodys bases scattered throughout the world. This application can also be used to do things like remove entites or change biomes, though we won't be covering that today.

First Minecraft tutorial that treats us like real people with brains that figure out the simple things... much appreciated. Great video!
heres our problem how do you get this to work on linux
@@markbrannan in the download and installation there's an explanation on how to install it for linux
you know, there exist people who play minecraft and at the same time don't know much about computers, believe it or not
If you run in to an error trying to open the "region" file in MCA Selector, then select the entire "world"-folder. Then you can pick it from there. It worked for me :)
Oh gosh thank you so much!! I'm glad I found an answer to my problem, thank you again! :))
thankyou so much !
13:54 for anyone who wants to delete chunks that havent been used much
Use this feature for my server, except selection is anything less than 3 minutes.. another useful one is to delete chunks with an Inhabiatated Time of 0 Ticks .. surprizingly it saves a lot of storage.
Also, I also found that chunks' InhabitatedTime can actually integer overflow to the lowest negative value (I believe 32bit? I forget) Basically occasionally I set any chunk's InhabitatedTime that had exeeded 10 hours, or near the integer limit (Max difficulty, eventually mobs stop spawning after this) to just under 10 hours or so... I had one accidental Thanos event without a backup due to storage constraints...
Well done overview. Exact use case scenario I was looking for!
Thank you for the tutorial! I was really struggling with backing up my 4 year old world that was just getting bigger and bigger. This is a lifesaver for me and my backup storage drives!
Tysm now just wait for 1.17 :D
@John 건 Benton wdym
@John 건 Benton vertical chunks have been in the game for literal years my dude. they're 16 blocks high within the 16*16 block walls of what you would normally see as chunks. it's the reason why mob farms work best when they're low down in the world as the mob spawning algorrhitm begoins in the bottommost chunks. next time you're playing minecraft use the f3+g command and you should see chunk walls and grids, but every 16 gridlines on the Y axis one of them is blue. that's the boarder of a vertical chunk.
gonna just factcheck that it's still got the blue gridline, so if you see this comment i've literally opened the game to double check i'm not Bullshootin'
fact checking correction the vertical chunk gridline marker is blue, for some reason I thought it was red, corrected before posting.
This is perfect for 1.18, because new and old chunks blend perfectly. I deleted some boring dead chuncks next to my base, now there is new, awesome, 1.18 generation next to my 4 years old home
And I finally got to fix my redstone testworld, which reset the preset once with updating and new chunks would be grass! I deleted them and changed the preset!
glad to hear that. I was wondering if they would all just look like chunk errors on all the borders of old and new
my old chunks dont blend evenly with the new one its so wierd
@@Infamous_wu13 you should check for Mods and game version.
@@arthuralpaca i had my world for years so its originally from 1.15 but since the 1.18 update things got wierd
what a life saver!! i was so worried i was going to have to start a new world to experience the new caves, this helped a ton!!
This will solve all my problems when 1.17 comes out, I hope.
It doesn’t :)
@@m1iles no thats just snapchot
yes hopefully cause it can cause chaos on my survival world
@@m1iles um why? the chunks get deleted and updated. Theres no reason why it shouldnt work?
@@bjorkws you obviously aren’t up to date new 1.17 worlds are 128 larger in height
Thanks. I have a lot of ‘mountains’ around my base area that I’ve never built on, it’ll be awesome to delete the loaded chunks and reload them as the new mountains.
depending on how old the world is they may not even be mountains after clearing them. chunk generation works very differently now.
Might not get the expected results. Could just as easily be a different biome now but should blend into the existing chunks.
I didn't know about the filter. That's useful. Thanks!
I just want to say that I love you man. Thank you for this!
Thank you so much for this video!! I'm gearing up to finally update my longplay server to 1.16.2 when it releases, this will make pruning so much easier! also you explained everything very well, thank you!!! subbed
My hard drive thanks you. This was a great video: clear, concise, exactly what I needed to know.
Thank you so much! I run a server for my friends, and we recently had one member who kept exploring new chunks excessively, even though we asked him not to. This takes a major weight off my shoulders; now we can get new 1.20 content without having to explore ridiculously far.
Your videos are so much more appreciated then I think you realize
Just used this application to trim my world for 1.17, will likely do the same with the next update considering all the world generation changes on the plate. Thank you for bringing this to my attention!
Thank you so much! this helped me find new terrain so quick and my performance is better now
Hey man! Any reason why the 'selecting filtered chunks' loading bar isn't moving? I've been sitting here for like 20 minutes. I'm a little confused. Thanks! 😅
Big thumb up to you mate ! Clear and understandable tutorial, perfect ! 🤙🏼
Extremely Helpful, Thanks for the Tutorial
very clear and helpful tutorial.
just straight to the point telling you how to download and use the tool and also giving some good advice on using the tool without creating problems
very well done
This is i was exactly looking for! Thank You for showing it off
THANK YOU! You helped me with my corrupted survival world! Works with 1.17 caves and cliffs previev datapack!
My world gen was wonky and this worked like a charm. Ur a legend.
thanks so much ive been playing survival throughout every version collect all unobtainable items and i have had to deal with terrible chunk errors due to changing generation this will fix everything
thank you very much i been looking for while to reduce the size of my world for a while now your the only one that had an actual solution +sub
Thank you! I can now fix my nether and play the update properly
This solved all the 1.17 update new terrain problems, thanks
Super helpful video, I just used this method to transplant my builds into a mostly new 1.18 world!
Thank you so much for this! With MC edit going the way of the dinosaurs, I was out of options for repairing corrupted chunks. Your video was the second google result for deleting chunks, and MCASelector is by far the fastest and easiest way to do so. Better than MC edit even.
I couldn't even delete a single chunk no matter what I select. With mcedit. With this like a charm.
@@norbucso it's says that this can take your pc to risk
@@ViShNu_K3 I always make backups of my world. But a small warning. If you delete a large portion of world and a render distance is 8 or more and the pc is slower like mine than the chunks freeze up with entities freezing. Like sheep and cows. So put it to 4 and walk around the parts slowly to load them up in newer minecraft versions. I thought I messed up but only problem was my laptop is not strong enough for the game. I mean AMD cards are not good for minecraft. My laptop is brand new and strong. Anyway. Make backup and you can use it pretty easily. Just make sure you have no hidden base under surface you forget and can't have it back after deleting.
@@ViShNu_K3 technically anything that can change files on your pc can be flaged as a risk to your pc.
McEdit is a god-like program for worlds before 1.12. It does absolutely everything possible in relation to editing a world. But in 1.12, file formats changed and McEdit was deemed useless moving forward and the 'new' version that was stated to be worked on never came to fruition.
MCASelector is awesome in the absence of anything better, but it can't even compare to function McEdit was back in the day. You could even write your own terrain generation code to use in McEdit as a filter. I created an entire fully furnished small quest map for my friends within a week using a combination of McEdit and WorldEdit with most of the heavy lifting done by McEdit. WorldEdit was only used to finalize smaller details. Custom spawners and Command blocks are then done with just vanilla.
Thank you for such a brilliant tutorial, Muriako! Very well presented; very useful information. I have learned a lot!
I wanna say thank you so much for this. I knew there was some program I could use to reset chunks to the new update while keeping the areas I wanted. I can't thank you enough!
Do you know if u should do it on a backup or on your actual world
@@RiceEater-xt9uy Make a backup but do it on the actual world incase it goes wrong, you'll have a backup
Thanks for the tutorial, this was very useful in fixing a ticking entity crash. 10/10
This Video helped me so much, know my survival world will get better
Thanks for this beautiful guide!
Thanks a bunch!!! I've been looking for that for a while.
@Roblox trading when you delete "chunks", it is already saved. You don't have to do anything else. That is why you need to be careful for what you want to delete.
I am so glad this exists as i may or may have not put a repeating command block to always active with the /kill @e command...
This is really helpful! Thank you, I will try it miself on my minecraft server
An youtuber from Brazil called Davi which has a series called Craft games, recommendend this video
Hummmm

Lifesaver, thank you so much!!
oh my godness i've been looking for a way to reduce my world size (it was huge, impossible to upload on any hosting server ), for like... forever- i just needed a video exactly like yours, thank you so much, ur epic!!! >
i love you, you save my server for the new generation
Super helpful! Thank you so much!
Fantastic walkthrough, thank you very much, this saved my existing world with some mod updates that added things I wanted.
What a great tutorial m8
Thank you very much!
Great video dude! Guess for getting the new 1.18 generation we will need to blend our builds in with worldpainter.
Thank you for this video! Very Helpful
Thank you! This helped a lot for me and m friends' server where we only had 5 GB of disk space and our world was getting too large, also it'll help out when 1.17 releases i hope
THANK YOU!!! i was worried about my world because i was stupid enough to play iit in the snapshot and chunk borders appeared but this fixed everything! never play the snapshoot in worlds you care aboout guys!
Great tutorial, thank you very much!
Super nice tool and review
Thank you man, you really helped me a ton
this helped me A LOT!! Thank you!
@Roblox trading The video explains it far better than I can. Just as he said, once it has done its thing it is irreversible, that is because the changes are saved the moment you start the process of chunk deletion.
Thanks. Since MCEdit doesn't work anymore, this has been insanely helpfull.
Will be using this on my SMP! thank you for making this video!
Can you please tell me how to do it in smp
I also have a smp and I have trouble figuring out how to do it
@@minecore1373 for sure! dm me on discord Dreeft#9664 and ill get back to you
@@DreeftYT Thank you
I sent you a friend request so you can message me and my discord tag is ConquerorAres#2542
This going to be so helpful thanks
really good video that is nice to follow. thanks for the work
Man you have to do more tutorials of this tool and all the things it can do
Like the copy n paste or chunk import/export. Thank you
This was very helpful, Take a subscription!
thanks for the help, absolute life saver
Great software, I previously tried MCedit and Amulet, both crashed and/or took ages
Thank you so much for this!!
Thank you so much! You saved my day! :D
This will really help me as my laptop isnt that powerful. Plus its better to have the new caves near your base rather than going out thousands of blocks
Thanks, helped alot!
very good application i was able to reset the already explored chunk from 1.13 world to 1.17
Amazing tutorial
This was very helpfull now i can debug my Minecraft server world
thanks bro at last i find my base!!!!!!!!!!!!!!!!!!!! love from india
Excellent video... now getting Ubuntu 18.04 to run Wine 5.0 to run MCASelector was a little tricky (wine repository pubkey issues).. but it works (text fonts are ugly, but I can deal)
tysm, i found my lost base with this
Are you feeling better about your video production process? I genuinely enjoy your videos and would be ecstatic to hear you were content creating again.
I've still been struggling to make anything I'm actually happy with to be honest, but recently I've also been more motivated to try harder on it. Sorry for taking so long, I'll do my best to get back to it!
This video is finely made.
thanks, this really helped
This is great. Now I don't need to abandon worlds when I add new mods or cheat to get blocks
Thank you SO MUCH
Thank for video it be very helpfool
Best explanation!
Thank you very much!
Thank you, so much.
Thank you so much!
Dono do canal: quem caralhos e davi
Great tutorial
Excellent tool for 1.18
Thanks for this, can update my server to 1.18
thats the tool i was always missing! in wonder if it can merge parts of seperate worlds. i always wanted ouur own worlds to be in a far away location in our current one, so we could visit. but for now, im happy to reset some chunks for the new world generation. thanks for telling us!
Could you please make a separate video on those Instructions? Because I honestly don't understand anything within those instructions and I'd like to delete quite a few chunks on my worlds to generate updated areas
Thanks man
Easier way to delete chunks outside an selected chunk(s):
- Select the area you want to preserve
- Then go to selection and click invert
- Done :)

Great video.
thanks bro
My oceans were 1.5 generated however they have like 4 monument in them. The 5th is in my spawn chunk. Which seems impossible yet it's there and a guardian farm with high yield. So those ocean monument will be raided and then if I delete those gigantic oceans will be full of life after. This program seems to be the best for this. Mcedit just don't do anything or I can't seem to use it. This works like magic. Thanks
AMAZING THANKYOU
I searched my pc for this because I downloaded it before, it found the directory from me downloading the source code
I then downloaded the source code again
usually there's an exe or equivalent and I didn't think that download button was different from what I was doing
thanks for pointing out the obvious bit that I could not for the life of me find
i thought this'd be a miracle application that i was crazy looking forward to. but, because it seems like it bases generation off of the world seed, no matter what, you'll always get the same generation in the new areas that you cleared each time.
my main world is from beta 1.8 and has chunk errors from release 1.2 when jungles were added and were plopped into weird areas on my world. since i've never done this kind of thing before, if i select the chunk errors, all it will do is spawn a new chunk and look like another chunk error. it doesn't blend new chunks with what's around it.
like i said before, since you'll always get the same new chunks to spawn every time, near my spawn, it's trying to spawn oceans not far away on two separate places and so it looks like my plains and mountainous areas are an island and just looks wrong.
i appreciate the video, but it doesn't really change anything since it just creates the look of chunk errors anyways and spawns the same thing every time. i did use it to redo my nether which doesn't look at all unnatural due to how the nether is, so that's nice. and i may use it to change biomes in a couple places because those have slowly shifted and changed in every update. oh well i guess.
and this comment is probably exhibiting “of course it works like that, duh.” this wasn’t a negative thing towards you or even the application devs. simply my ignorance on this and being disappointed because of it lol.
Unfortunately what you need is vastly more complex and niche, there's not really going to be an automatic way to solve that.
However, what may be of use to you is a program called WorldPainter. It's mostly for making custom terrain, but it would allow you to essentially "paint" your terrain to blend those different areas together. This is a much more manual process and you would need to do this for every area you wanted fixed, but it's definitely your best bet. I actually went through that process quite some time ago on the world I used in this video for similar reasons, though if you rush it like I did at the time you can have some artifacts like distorted trees lingering around in some spots.
As always, make sure you have a backup before you start doing any of this if you want to try that method out.
Muriako well, i will look into that. like i said, this video was still useful and well put together. i at least got my nether sorted with this method. i appreciate the other recommendation.
thank you
My hero
Very good tutorial, thanks.
I got a bit of a obscure problem, I guess. I am playing a very, very old world. That world was first created in Alpha 1.8, I think. God knows how many years ago that was. I remember how the update that introduced beds somehow screwed with my previous world and I had to start that new one, but ever since, I stuck with it, because I didn't want to give up on all the stuff I had built. So I rather ventured out further and further, every time new biomes and other stuff was introduced.
That made everything outside the center of my world pretty uggly. Many jagged, unnatural cliffs, many biomes overlapping each other in ugly, angular shapes. For example there will be a snow biome with a 10 block wide strip of a desert biome running through it and nonsense like that.
I also used MCEdit, when that still existed, to copy and paste cool stuff into that world.
Unfortunately, it got pretty screwed up over the years.
There are certain areas where the game always starts to stutter and the frame rate drops like crazy, even though I run the game on a pretty powerful computer.
I guess something I did somehow screwed with the world in those places, somehow damaged it.
Now I hope to either, somehow be able to use MCASelector to either clean up and repair my old world, or maybe copy and paste the stuff I don't want to give up into a new world.
Maintaining such old worlds is definitely a challenge. The world I was modifying here is probably 8 or so years old at this point as well, and had already gone through some massive surgery due to updates and prior corruption.
Cleaning up those old areas will still result in broken generation with blatant edges on all sides, but if you can do it with large areas it may still help clean up some of the mess at least. Unfortunately I don't think there's any particularly easy way to actually make that terrain from different versions blend nicely. In the past I used WorldPainter to smooth out the transitions, but it's a lot of work and can cause some messy results if you're not careful with it. Worth considering for any areas you particularly care about though, as are mods like VoxelSniper/WorldEdit, just be sure to have backups before attempting any of them.
@@Muriako Thanks.
I'll check it out.
I did delete an object I had copy and pasted into my world years ago, but didn't like anymore and that one apparently caused some stuttering too, because I think that got better when I am in that area, since I removed it.
One strange thing remains (besides my problems with copy and pasting, I mentioned in another comment). I can't open my Nether or End with the program.
When I select DM-1 or DM1 with it, all I get is a blank, black map, as if I never had been in either dimension.
I
have 12 gb world and i need it to be less that 5 gb. Thank you so much, this will difenetly help me
