Minecrafts Most BROKEN Seeds Were Just Discovered…

About three weeks ago now I was casually browsing the Minecraft seed subreddit when I came across this strange post sinkhole’s breaking minecraft generation a seed collection looking through the 20 or so images attached and in my over 11 years of playing Minecraft I had never seen anything like them before in the

Middle of these gigantic Lakes were these massive holes containing various unique terrain generation as well as large structures almost as if somebody had World edited a hole into the world to say the least it was extremely unusual and fascinating and then I saw this the most bizarre and broken

Minecraft seed I’ve ever seen with half a dozen structures generating either in the wrong biome on top of one another or all in the exact same location so what exactly is going on here well the story mostly begins with this seed in a post only a few days earlier on the Minecraft

Seed subreddit a user by the name of cracked magnet shared a seed upon generating the world all seems normal until you approach this large lake now large lakes entirely enclosed by land like soy are already quite the Rarity to see in Minecraft terrain generation but upon seeing a massive hole in the lake

It doesn’t seem as unusual by comparison anymore if we swim to the center of the lake you can see there is what seems to be a large hole with various caves trees grass and of course lava at the bottom which is that Bedrock level and yes this

Is a naturally generated tree all the way down at y level negative 46. let me know if you’ve ever seen lower I personally haven’t if we look at the anomaly from the outside we can truly see how odd the terrain generation is and it’s almost like somebody uses

Sphere tool and world edit to crudely form the sinkhole from the outside in the generation was truly odd and clunky with seemingly no proper flow at all but hey because it’s so deep you have direct unobstructed access to Diamonds if you can swim down from y level 60 to Y level

Negative 30 and mine the diamonds without drowning that is things got even stranger on Bedrock though with this other seed cracked magnet would post only a day later if we go to these specific coordinates where we get the most absurd thing I’ve ever seen in Minecraft period not only is there a

Super odd ocean Monument but there is a massive Woodland Mansion stacked right above it which is nowhere near dark oak forest mind you with a village to the side of it a Pillager Outpost above it which ascends above the clouds and two floating aquifers if we walk inside the

Mansion slightly you’ll also find a Buried Treasure and then below the ocean Monument you guessed it a God damn stronghold in what seems to be a suspended cave in the middle of this massive body of water none of this should be possible in Minecraft it shouldn’t happen the structure should

Have failed their biome checks the ocean Monument isn’t even in an ocean the Mansion isn’t in or near a roofed forest and yet here we are here we are almost at 500k Subs be sure to subscribe for me would you no pressure of course so after seeing the abnormal seeds another known

Seed finder Geron decide to look for more and would eventually make the post I mentioned at the beginning of the video I got in contact with the charot to try to understand what exactly is going on and how to find such seeds Giro used a program called qbiome’s viewer to

Find the seeds cubaam’s viewer is a cool program which creates a graphical interface of a Minecraft seed allowing you to view the seeds many biomes structures and other unique terrain generation features in a top-down bird’s eye point of view the program also allows you to search for seeds with

Specific and unique properties analyzing the seed crack magnet found in cubaims viewer jaroon noticed that it generated a ring of the Lush cave biome at y level negative 64. you can see this in game if we go low enough and fly around the sinkhole in spectator the biome is

Always Lush caves coincidentally prior to this Giroud was looking for a seed with a lush cave combined with an ancient city while doing so Giroud discovered that when the Lush cave biome showed up a y level negative 64 and there was no Ocean or river around it it

Meant a lake had formed on the surface of the Minecraft world so knowing that crack magnet seed had a ring of lush biomes at White level negative 64 and having the previous knowledge that these rare Lakes generate when there is a lush cave biome at White level negative 64 as

Well Giroux updated his Q by Monsieur settings to look specifically for this Lush K5 ring the first set of sinkhole seeds were found using this method but they were very small nothing worth sharing with the community fortunately though cracked magnet C discoveries had sparked much discussion among seed

Finders in Minecraft at home and the Minecraft seed subreddit discords who decide to look into the game’s code to figure out what exactly is causing these abnormalities to generate they found that the primary driver for these weird sinkhole seeds is something known as the weirdness value you can see the

Weirdness value on the F3 screen here and in a normal Minecraft world the weirdness value generally fluctuates between 1.2 and negative 1.2 rarely exceeding either mostly hovering around zero as weirdness is normally distributed however as you can see on cracked magnet seed the weirdness is at a very rare number below negative 1.2

Being being negative 1.9 and this was the key to the sinkhole Minecraft seeds and just to clarify weirdness is one of Minecraft’s noise values used in terrain generation basically having a strong influence in the height or depth of land you can see here that this graph displays that when certain conditions

Are met extreme weirdness values lead to terrain depth rapidly decreasing there’s a lot more to it though I’ll leave an article below if you’re curious so with that knowledge shuru went back to the coupon if you were to search for scenes with abnormally low weirdness values but there was a problem qbiome’s viewer

Allows you to search for weirdness values between a certain range but that range was far too big being from negative 9000 to infinite weirdness so Giroud tinkered with the session files to set a search radius of negative 19 000 to negative 23 000 weirdness geru

Then over a span of a week search for seeds getting back over 1 000 with low weirdness of which 33 to 50 percent roughly generated sinkholes adding a depth biome layer filter to the GUI allowed Giroud to determine whether the sinkhole generated or not you can easily

Tell when a sinkhole is present as there’ll be a big black circular blotch which you can hop your mouse over to get a depth value generally depth values in the negative six to seven thousands indicate large sinkholes because the biome checks don’t properly exclude the placement of structures in these

Sinkholes although you can find odd structures generating in or near them which only make them even more interesting you can check this in chunk Base by looking for marks on the map like this and adding in structure filters but that still doesn’t explain how we got that absolutely busted

Bedrock seed cracked magnet showcased well let me explain as the recent sinkholes generate and the structures generate all in the same place like the seed are actually related in Minecraft Bedrock there are values which determine what biomes generate what the layout will be and what structures can generate

In that world at specific locations when a structure is being put into the world it’s given a midpoint with a small parameter of blocks you can generate above and below it so for example the midpoint could be 64 going 32 blocks up to 96 and 32 blocks down to 32. the

Midpoint for structures when they generate is determined by world’s preliminary surface height which is basically an estimate of the height the highest block will be at when a chunk generates when that surface height is below the minimum World height which is negative 64. it outputs the highest number it can 32

767. when that happens any number added causes this value to roll over or overflow and become negative and thus break leading to structures ignoring the biome check altogether and why does the preliminary surface height go below the world height well it happens when weirdness reaches unusual values the

Same reason the sinkholes generate on Java in the first place cracked magnet has more detailed information in this video here so is this a Minecraft bug well we don’t exactly know you see in Minecraft Java 1.19.3 sinkhole generation was actually fixed however as crack magnet told me he couldn’t find

The fix anywhere in the release notes and even more strange without going to detail for this fix to work the preliminary surface height still has to break and dip below negative 64 leading to the Overflow making this entire situation very unusual if you want to see the sinkholes or player world with

Them create their own than 1.19.2 and generate the sinkhole and then update it to 1.98.3 and keep playing so let’s take a look at some of the more interesting sinkhole Seas found by Giroux shall we here’s the first a smaller sinkhole but with a gigantic Woodland Mansion protruding out of it

Would make for a cool base in addition with the jungle terrain that is generated down the side of the sinkhole from a more vertical point of view the matching actually looks really cool isolated in the middle of the lake C2 here is unique because the lakes around the sinkhole is actually Frozen in

Addition the random mine shaft platforms look like the beginnings of a cool parkour that could end at this open amethyst geode seed 3 is certainly one of the more picturesque sinkholes surrounded by a beautiful mountain-sided Meadow you may notice that the water’s tint is a much nicer dark blue due to

The meadow biome making the water which spills into the sizeable sinkhole look Enchanted and beautiful just on the side of the sinkhole is a village which has sprawled over right to the very edge of the hole my personal favorite seed so far seed 4 looks quite boring by

Comparison from above but what’s coolest about this sinkhole is what lies at the bottom of it at the bottom of the sinkhole is the beginnings of a gigantic ancient city part of which is entirely some emerged in an underwater cave seed fire features a village of which some of

Its residents who are daring enough to settle in but ultimately is one up by seed six whose Village residents were so gigachad but they decided to live entirely at the bottom of the sinkhole itself now this is a site you don’t see every day an entire Village primarily

Built on deep slate surrounded by not only lava but also exposed Redstone and Diamond oars as they say life finds a way seed seven found by cracked magnet also showcases a group of villagers tempting fate at the bottom of the Minecraft Earth although these guys seem more organized this sinkhole Village

Combo is also surrounded by a frozen lake if that’s more of your thing however the most unique thing about this seed is the igloo which has generated in the middle of the frozen lake with an entirely exposed basement section I bet you’ve never seen anything like that before enabling the large biome setting

Allows us to find some more unique variations of such sinkhole seeds here’s a Badland seed with jacket like pigs sticking out of it if we switch to bedrock Edition there are also some very uniquely broken scenes here we have a Seed where there’s a floating village connected to a small sinkhole which has

A photo voting aquifer and Island right above it with this water pouring in then we have a super broken ocean Monument sinkhole seed combination of which the ocean Monument has had its supporting pillars generate all the way down the sinkhole into Bedrock level by far the deepest ocean Monument I’ve ever seen

There’s also some strange floating water behavior and not just like floating water we’ve seen on Java before this is seriously uncanny to look at cracked Magna actually found this seed only five days ago now which almost Rivals the sixth structure one we saw earlier now not only is there significantly sized

Sinkhole right at spawn but there are various aquifers throughout the sinkhole that Ascend far above it into the sky even Beyond Cloud level oh and let’s not forget the absolute extreme survivalist desert Villages who decided that out of all the perfect normal land out there that the middle of this anomaly will be

The perfect place to build just imagine casually exploring the desert and seeing this monolith show up in the distance it would be a memorable Discovery that’s for sure and finally I’m going to show you a special world crack magnet generated by overriding the weirdness noise value manually basically if the

Stars aligned this is how big a sinkhole could get in game and Jesus Christ this thing is ginormous and even contains a massive Village which is quite literally floating on lava at the bottom of it now this is truly extreme survivalism the thought of randomly stumbling upon this

While playing your Minecraft world is hilarious to consider I mean what would even run through your mind I know that I would probably have thought it was some obscure chunk error or World corruption a base in the dead center of the sinkhole could look so cool as well it’s very unique Terrain

The recent discovery of these sinkhole seeds is awesome and there are still many more unique ones that can be found in both Java and Bedrock if we go to this seed here which is a roofound that was generated with the large biome setting you can see that the sinkhole

Has removed the layers of Bedrock leaving only the absolute bottom single layer separating the void and the normal Overworld when this location is analyzed in chunk base it displays a y value of negative 116. this should be impossible as the loss of Minecraft world can go is

Negative 64. and that is correct but what chunk bass is doing is taking into account extreme weirdness values which makes chunk base think of the Minecraft world goes down to why negative 116 instead Minecraft most certainly has some code in place to prevent such An Occurrence from actually happening but

There is a very small chance that certain seeds where Bedrock has been broken giving access to the void could be found in the future I hope you enjoyed the video be sure to check out Giroux and crack magnet of course both were super helpful in explaining the technicalities behind how such seeds

Came to be subscribe to me as well while you’re at it thank you all so much for watching
