How 3D Minecraft Maps DESTROYED 2b2t

if you've played minecraft before there's a good chance you've crafted a map at least once but have you ever seen one do this what you're looking at is not an illusion or a mod it's a legitimate map players on the oldest anarchy server in minecraft have found a way to make three-dimensional maps and in the process have weaponized them what was supposed to be a fun novelty at first has ended up as one of the most catastrophic crash exploits in 2b2t's history these maps have crashed the server multiple times over the past week with the downtime often lasting hours they've caused massive amounts of lag to everyone online completely brought the q server offline and can even softband players from the server if they're in the same chunk as one it is completely different from previous crash exploits which is why it's been so destructive and hard to deal with so why has a simple minecraft item been capable of causing so much chaos today we'll be discussing how 3d minecraft maps were weaponized on 2v2t and the technical explanations behind the exploit we'll even see these maps cause havoc in person on the actual server and witness the fallout of them being pushed to the absolute limit i've played on 2b2t for over 8 years and i've never seen anything quite like this so buckle up this is a pretty crazy exploit but i do have an announcement before we start you know how in the past honey has sponsored several of my videos they recently told me that all the fitmc fans that have used it saved a combined total of almost thirty thousand dollars on their online purchases that's insane if you don't know honey is the free online shopping tool that searches the internet for promo codes and applies them to your shopping cart automatically when you're checking out from online

deals honey works on lots of your favorite websites if you don't want to waste money make sure to get honey it doesn't cost anything and finds coupons with a click it's legit get honey for free at joinhoney.com fitmc that's joinhoney.com fitmc now then let's get started so who exactly was the first person to figure out how to do this on 2b2t well it all started a few weeks ago a player named city boss was playing around with maps in single player he made an area full of item frames and different copied maps during this process one accidentally glitched and the markers on it became 3d which caused his game to start lagging he didn't understand what was happening so he brought it to the attention of his friend rebane who's a known map artist in the community rebane was surprised but he knew exactly what was happening he gave an in-depth explanation as to how it worked in the java version of minecraft a green marker on a map represents an item frame and this marker is placed onto the map as a two-dimensional icon normally if two or more markers were in the same location it would cause visual tearing also known as z fighting to get around this minecraft maps are programmed to put the icons slightly on top of each other to prevent this tearing from happening so anytime you see a marker on a map it's not actually touching it most of the time this effect is not noticeable but once thousands of markers start showing up it becomes very clear that they are being stacked in a three-dimensional space once you get up to around a thousand markers the maps begin to require additional resources to render this puts a strain on computers causing fps lag and other issues if they were starting to lag at just 1 000 markers what would happen at ten thousand or a hundred thousand or even higher they hopped on a testing server to try it out and their results were absolutely insane they found a way to duplicate the map markers by going in and out of the nether this allowed them to stack more markers without requiring additional item frames so they could in theory stack the icons forever but it turns out there was a hard limit when enough markers were in render distance it dropped your frames per second low enough to effectively crash your game to get around this they developed a mod that would hide the icons from their screens preventing the crash with the frame rate issue solved they attempted to make the icon stack as large as possible but this brought about a new issue the map was becoming so big that it was sending too many data packets to the testing server causing it to become unstable if multiple copies of the maps were placed in the same location it completely crashed the server the fact that this exploit was capable of crashing someone's game as well as the server they were on made it especially dangerous and both city and rebain realized how powerful it would be on 2b2t the maps did have some weaknesses though if the server restarted it would remove every duplicated marker from the map so they would have to be added again and because 2b2t had far more powerful hardware than their testing server it would require a greater number of maps to crash but it was clear that city and rebain had effectively found a way to weaponize maps but just how much destruction could they cause it turns out a lot [Music] the two began sharing knowledge of the exploit and they started testing their first map they called it the pop bob crash map as a joke since they knew how much chaos it was going to cause on the first day of the exploit being used they managed to kick many unsuspecting players back into the queue with it and were able to discreetly start lagging the server after hearing about what was happening i was invited to come see the map in person i still had one of my alt accounts at the valley of wheat so i requested they meet me there they showed up and quickly began the demonstration i was handed a map with 40 000 markers on it just holding it in my hands brought my frames per second from 600 to 36 when they started placing multiple copies of it in item frames it dropped even lower eventually crawling all the way down to just two looking away from the maps was the only way to not get lagged out if my pc were any weaker i would have easily crashed out of minecraft altogether one poor soul that showed up went too close to the maps and actually had his game crash while he was suspended in midair having multiple players around these maps caused the server to begin lagging even more and that was only with 40 000 markers they told me they were planning on making a map with even more i knew things were about to go from bad to worse the next day a new map was constructed that contained hundreds of thousands of markers when i visited this map all it took was just one of them in render distance to bring my frames per second down to zero what you are seeing on screen is real time footage not screenshots so even my top of the line gaming pc couldn't handle a single map the stack of markers at this point extended over eight minecraft blocks away from the map itself and i was even able to see the markers extend in real time at that point i was instructed not to pick up the map itself as just having it in your inventory would automatically kick you from the server for sending too many data packets as the map was extended even more players began placing them in common areas around the server spawn the nether highways and even the end dimension rebain ran some calculations and found that each map was sending two megabytes of data to the server per second by having thousands of them loaded it was sending gigabytes per second the sheer amount of maps being loaded across the server at once caused it to go haywire in computer hacking sending too much information to a server is called a ddos attack or distributed denial of service all the major minecraft servers have protection against these attacks but only from the outside these maps were causing 2b to perform an attack on itself from the inside and so the server began to collapse first the q server stopped working causing players to be stuck in position zero or unable to join at all the online player list was reduced to a single column of players for the first time in ages the majority of the community had no idea what was happening and this confusion caused even more chaos many of those that survived the kicks were frozen in place and couldn't move for minutes at a time eventually the map was pushed to the extreme limits with 700 000 markers on it stretching over 10 minecraft blocks long this single map was now more powerful than every previous crash and banning exploit in the server's history combined you couldn't hold it look at it or even be online when someone else was looking at it right after the 700k marker count was reached the server completely crashed 2b2t's admin housemaster immediately intervened by forcing a restart which removed all the green markers from the original map he world edited the crash map's location while also implementing a temporary limit on how many item frames could be loaded in a single chunk while 2b2t was safe again for now the knowledge of how to perform the exploit began spreading and was attempted on several other anarchy servers as well it's a common joke in the community that 2b2t players can find a way to weaponize anything that exists in minecraft but seeing how effective these maps were as weapons is actually shocking the fact that my pc almost burst into flames recording this video you better be hitting that subscribe button also follow me on my socials but that's it so take it easy fit fam and stay away from maps alright
