Converting Old Worlds To Minecraft 1.18

All right everybody welcome to the real caves and cliffs update i’m sorry i don’t buy into any of that part two nonsense i don’t know exactly what 1.17 was maybe the axolotl update but it wasn’t caves and cliffs 1.18 this is caves and cliffs he says well clearly

Still on 1.17 in the bottom left corner hold your horses okay we’ll be on 1.18 in a minute but we’re here to do science and in order to do science we got to start off at 1.17 because i’m sure there are some people who are thinking yeah

1.18 looks super cool and all new extreme world generation but what happens when i bring my existing worlds into 1.18 that were made in previous versions so we’re going to test that well yes i might have already tested but i don’t like to go into videos completely blind okay i gotta know my

Stuff so this would be blendy too and we’ll set it to creative and make a new world and while we’re loading this is a great time to tell you all about our incredible sponsor the like button which you should be sure to click or tap below the video depending upon what

Device you’re watching on look at us here in a new world where i’m not going to move around what i’m going to do is just fly up and i have my render distance set very very low to six chunks reason being i just want to get a nice little area here

Loaded and then we’re going to take this into 1.18 and then we can just up the render distance and all of a sudden we’ll get a bunch of 1.18 chunks loading on the borders here and we’ll get to see how well they blend in because that was

Like a huge thing that they announced during minecraft live but with blending it will smooth out the terrain so it looks like it fits more together oh good forest fire i wonder if that’ll carry over to 1.18 anyway i think maybe even cooler than just blending the

Chunks together on the surface is that in our existing 1.17 chunks here that we’ve already loaded it’s actually supposed to retroactively insert the negative y value parts of the terrain where the deep slave is and what not so right now the world ends at y equals zero obviously that’s where the bedrock

Begins we can’t do anything below it but once we bring this into 1.18 we’ll have all of the stuff that would be under here as if we had just created the world so your old worlds will have all the deep slate stuff a bunch of new ores places to strip mine and uh

I want to check that out in action so that said i think we’ve got a good overview of what this place looks like so let’s bring it on into 1.18 and see how it blends together oh hey that splash screen’s more like it now i can actually say welcome to the real

Caves and cliffs update okay so we’re gonna open up the same world on 1.18 here the interesting thing is it doesn’t even prompt you like hey this world is from a previous version are you sure you want to load it you could have issues it’s just like nah we’re good we’ve

Tested this a whole bunch we know that it’s going to fit right into 1.18 you’re not even going to realize that it was an older world like usually on when you’re moving from previous versions to a new one it’ll like give you that little prompt but here’s just like no no

You’re good we we got you here we tested this extensively uh your world’s gonna be fine so here we are everything looks the same because again we haven’t upped our render distance but now this is gonna be the uh moment of truth here okay so let’s go into our video

Settings and we’re just gonna bring it way way up and it blends in the swamp just continues turns into planes over there the mushroom forest continues wow this is pretty impressive actually honestly you can’t even tell dude we got some mountains going they’re forming over there that’s some caves and cliffs

Terrain over there look at that look at that over you can’t even tell though it just like just blends together that’s one cold swamp over there and look the forest fire you can carry it over what do you know oh there we go now it’s blending into some new terrain

It’s really cool yeah you cannot tell where the initial chunks stopped and where the new ones began there’s no like jagged edges let’s go underneath look at this okay so this is really cool so we’re gonna get to y equals zero right here and you can see right like

All of the previous bedrock has been turned into deep slate and you can see that there’s a little bit of a cut off there right it’s not a it’s not a smooth ending and you can see all across this area in these chunks that we first

Loaded like you can kind of tell if you’re in spectator mode like where it ends but then if you dig through you’re just gonna right end up down here we haven’t moved in the x or z direction yet so this is still this is right underneath spawn

And you have all these new caves and cliffs caves and and deep slate areas and you know more diamonds over there chilling oh that’s so cool that’s so cool and obviously we only loaded a few chunks in our existing world like you take a world

That you’ve been in for a while a big existing one and you’re gonna have like so many so many new areas and then of course what we can do is if we move over a little bit as we struggle with like the 30 chunk render distance i want to

Try to make it to like the edge of where we generated before and see if we can notice a cut off i think i think we might is this a cut-off it’s see it’s even it’s hard to tell actually the fact that it’s hard for me to actually find the edges even underground

Is really really impressive i’m sure if we look closely enough we can kind of find where like one of these caves just runs into a wall and doesn’t keep going kind of like this over here but still it’s like pretty smoothly integrated i think this is it right here yeah

You can kind of see that this uh this whole area just gets cut off right and then this gets cut off here so yeah i believe that this right here might be our might be our boundary you really you really can’t even tell where the old

Chunks were like if i if i keep flying around i’m just gonna end up actually losing track of where my spawn location was so um color me impressed they were confident about not needing to warn you and i can see where that confidence came from it’s uh it blends

In like super super duper well and this is like this is probably the most extreme example where i can see in all directions very little trunk loading and then all of a sudden everything loads and blends together and still it’s hard to tell so if you have a world where it’s bigger right

It’s going to be almost not noticeable at all let’s go again let’s go again these chunks generated in 1.17 let’s increase our render distance and see how it blends this is a new series on youtube called will it blend never before seen never before done look at that oh my god

There goes the swamp into big old caves and cliffs mountains over there oh oh and it’s going and it’s going and it keeps oh and then there’s a village on the mountain okay this is oh look at that oh look at that up it goes look at the blend will it

Blend the answer as always yes apparently oh that’s so cool oh this was like this was an absolute unit of a mountain range that generated like we were in like a a valley bowled here oh wow dude this is sick look at how this turned out mountains on

All sides is crazy this is the real caves and cliffs that’s what i’m talking about it’s perfect just blends together incredibly okay one more time now we got a jungle there’s a couple of rivers it’ll be interesting to see how those continue let’s go again will they be super cool

It is it’s continuing the river the river’s still going oh look at that still looks like fairly jungly no like super big cliffs or anything like that but it transitions into a desert you just can’t see the boundaries of where it starts and where it ends as far as the new

Chunks of the old chunks then we get a little bit of a hill over there up to a meadow maybe and then you know if we go down underneath you don’t even notice like the mine shaft looks like it’s continued as you expected if i were wandering through that i wouldn’t have

Even realized that i i crossed into new chunks and then this is all underneath the uh existing stuff anyways you can see where the uh the cutoff is here that’s really the only thing that you can still see is if you’re in spectator and you get right along y equals zero in the

Existing chunks you can kind of see that divide of deep slate where the upper caves don’t connect into the lower caves but beyond that it’s like i mean look at this look at this this is sick this is awesome i did want to show a couple things though in that first world

That i i tested out in before i started recording because there are sometimes little things that can happen but not really a big deal and compared to how well the whole blending together seems to work because works really well it’s very impressive oh it’s so cool overall everything works

Really well as you’ve seen but occasionally there’s a hiccup like a village starting to load on the edge of your 1.17 chunks and then you bring it into 1.18 and it’s like hey look the ground blended together really nicely but uh the house might have gotten cut

In half and the rest of the village didn’t generate but it’s a small price to pay for the beautiful chunk blending we get everywhere else also this tree might have lost a few leaves but you’re still a beautiful tree you’ve still got plenty of leaves on that side

You might you only look slightly like two-face if one of two faces halves were just not there the one nice thing about this though is that in previous worlds i was having trouble figuring out exactly where the edge of the new and old chunks was this

Gives us a really nice indicator so we can go underground and see exactly what it looks like right on that border and now that we’re here and we know it like it’s a little bit easier to see right you can see this cave kind of ends a bit

Abruptly it happens kind of on on either side here but ultimately like if you’re down there mining or in a cave right you’re not in spectator mode it’s gonna be pretty hard to notice right you’re not gonna reach the end of this right here and be like

Oh that cave was definitely supposed to go further but it definitely just got cut off due to the uh the new terrain generation like no it’s it’d be really really hard to tell actually so um even even knowing exactly where it is like it’s it’s well done

Other than the chopped in half house so sorry again villagers but uh those are the the casualties of progress all right well anyway i think that pretty much wraps it up here so thanks everybody for tuning in i’m i’m thoroughly pleased by how this has turned out hopefully you found it

Informative make sure to like the video subscribe to the channel stay tuned for more stuff from 1.18 or whatever comes in the future and that’s pretty much it i’ll see you next time
