Lava-Casting Inside A Mountain! ▫ The Minecraft Survival Guide (Tutorial Let’s Play) [Part 292]

Hello everyone my name is pics riffs and welcome back to the Minecraft Survival Guide I hope you guys are having a good day today we’re starting out over here on the back of this mountain that I’m building which is currently the tallest mountain in our mountain range and is

Certainly proving quite the task to built I’ve got quite a decent amount of it set up including what I think is going to probably be an entrance to a dwarven base build I’ve been thinking over this and I originally wanted this to be a ski slope but then it happened

To meet up with this section of the rock face where we built this kind of overhanging section I actually really like this I think this is one of the cooler elements that I’ve added to this mountain and I thought what if we have some kind of redstone door with honey

Blocks and slime locks that can open up this entire section of the mountain allow us to step through onto the inside where we will hopefully end up having some kind of dwarven ruin in there maybe even an active dwarven base although there aren’t exactly you know dwarfs

That we could populate it with but I think it would be kind of cool to have some kind of Lord of the Rings esque build in there with giant pillars reaching super high up relatively speaking at least and I reckon we can do some cool stuff with the interior of the

Mountain and I’ve been thinking about that more and more as we continue with this project I’d say we’re probably about halfway done so I still intend to continue it into at the end of March and possibly the beginning of April as well but I think we can come up with some

Pretty cool stuff to do inside these mountains and that’s a question that I’ve been asked more and more as this project continues is what are you going to put inside of the mountains there is so much empty space in here that people seem like it’s a wasted opportunity if

We don’t build something inside of here and you know what I kind of agree but I think some of these mountains especially this smaller one over here gives me a good chance to explore some other interesting building techniques and we build into this mountain in previous

Episodes and seen quite how vast it is and quite how difficult it’s going to be to light up this entire place but I have been wondering what if we attempt to fill in sections of this mountain now I know what you’re thinking that’s going to be a lot of blocks and you are

Correct I’ve not at all considered filling in these mountains manually because the sheer amount of blocks it has taken me to build them so far would be exponentially multiplied by filling up the entire inside of this like it’s a difference between drawing a line and drawing a square and filling in the

Square and considering how much ink you need for each of those things you probably need the most ink to fill in everything in the middle here so what I think we will end up doing is attempting to lava cast the inside of at least a section of this mountain to give it a

Try and see what we can do with that as a technique so what is lava casting you may be asking well in previous episodes of this series we have taken a look at cobblestone generation in fact over here in this very project we have a cobblestone generator using water and

Lava to create cobblestone and then creating it infinitely pushing it around with pistons and allowing it to form into blocks that we then break up for cobblestone in this case though I think we might actually try generating a bunch of lava and a bunch of water at the top

Of the mountain letting them fall down and spread out and then building up a layer of cobblestone by alternating a water and lava in that fashion so every time the lava hits the bottom of the mountain down here it would start to form a flat area and then you could

Cover that with water to turn it into cobblestone and then repeat that process lava and water lava and water until you end up with a kind of mountain of cobblestone basically rising to fit the inside of the mountain itself and we might even be able to use dispensers in

Order to automate this process a little bit now there are going to be some advantages and disadvantages to this approach I think one of the disadvantages being that once we get closer to the top it’s going to be more difficult for the lava to flow down the

Sides but I think we’ll at least be able to end up producing quite a large kind of inside mold like kind of used the mountain as a mold and fill up the inside of it with lava and we will definitely be reducing the amount of space in there where mobs can spawn the

Amount of space we will need to light up I think it might be a good thing to attempt at least and if you want to use techniques like this in order to build a mountain in the first place it won’t necessarily look like the most organic

Thing but it could certainly save you a lot of manual stone placement so for this we will need one or two buckets of water I’ll grab a bucket of lava from a nearby lava lake I’m pretty sure we still have one of those over here on the opposite

Side of the project the one that we used to grab the lava sources for this cobblestone generator and we’re I’m also going to bring my camera account in so we can see this in action on the underside of the mountain not an essential part of the process but

Definitely one that’s going to allow us to time-lapse some of the process because let me tell you it’s going to take a while hey folks welcome back so here we are at the top of the mountain on the back side of it where we haven’t quite placed any

Snow blocks yet and in here I’m gonna be setting up a couple of dispensers facing inwards towards the same block we want to have one there and we’re gonna set one up here as well so I’m just going to pillar around a little bridge around a

Little bit here and we will pop down this now I’m also recording this using my camera counts which is probably why you guys can hear a little bit of spider and skeleton noise as they roam around in the background I’m gonna be placing a lava bucket in this dispenser here we’re

Gonna place a water bucket in this dispenser here and we should be able to make a couple of buttons like so yes there we go okay so now when I press this button here that should just activate this dispenser underneath here there we go and oh okay that has just

Destroyed that lava source I guess weird I wasn’t expecting that button to power that block but I guess it didn’t it powered that dispenser okay that’s my mistake let me go ahead and grab myself another lava source real quick okay let’s now put the lava bucket in there

Let’s break out the block above it so hopefully now putting a button on this block here won’t affect it we could also put buttons on the site of the dispensers which all-in-all might be a slightly better move there we go so we now have a lava in this dispenser and

Water in that one best to remember that now as you can see the water is still making its way down the pillar that we’ve got in the center of here I thought it was probably best to have this thing basically against the pillar here and it’s trickling its its way down

Into this section down here by the river now what I’m thinking about doing is maybe setting out the lava now the water will probably end up dispersing before it gets to that point and this is why you need a little bit of space around it

Or maybe even a block there just to make sure that the lava doesn’t flow anywhere it shouldn’t but the idea here is that we are going to be dropping lava from a great height and waiting for it to spread out at the bottom of this pillar then we’re going to remove the lava

Source we’ll wait for it to drain off a little bit and then pour water down on top of it what that’s going to do is cause the water to turn all of the lava at the bottom of here into cobblestone creating a platform from which we can continue the lava casting

Process now naturally this is going to take a while primarily because lava moves incredibly slowly even when it is flowing downwards affected by gravity like this it is moving at a snail’s pace and that is why I figured we could do well to time-lapse some sections of this

Video to see how we get on but as you can see in the camera account view now the lava is making its way down to the bottom here where it’s going to start spreading out lava and water having fluid physics will both take the direction that causes them the least

Obstruction to travel down so that is going to mean that they will spread out a little bit but they will not spread out in a perfect circle around the bottom there however we are seeing a fair amount of spread towards the bottom and that will create a platform that’s

Going to even out the landscape once it is turned into cobblestone and allow the lava to spread even further so I’m going to remove the lava source now it should be spreading out plenty at the bottom down there we’re going to wait for some of the lava to disperse and then before

It reaches the bottom so that the water has time to flow down as well we’re going to release the water and hopefully that should convert all of the flowing lava down there into cobblestone and there are really two ways of doing this there is the patient way where you wait

For the lava to get all the way to the bottom of this and there is the impatient way in which you turn on the water immediately and cause the water to flow down there turning the lava into cobblestone from higher up and causing it to spread out a little bit further

The problem with that being that you end up creating air pockets that way because the way the lava flows and when it turns into cobblestone the way the water flows over the top of it will create some gaps in the foundation that you’re building so it’s often better much as it is maybe

A little bit painful to sit around and wait for this long to wait for the lava to disperse a little bit more before you end up casting your first platform of lava so I’m gonna wait around here for a little while just to wait for this lava

To drain off and then once it’s got to the bottom will activate the water and we’ll get a platform a cobblestone down there Okay I think I would estimate that the lava is now getting close enough to the bottom that it will be safe to release the water remember the water is gonna be flowing a lot faster than the lava so we do need to give it a little bit of extra

Time for the lava to disperse but I think from now we should be able to activate the water dispenser yep there you go it’s flowing down very very fast it’s gonna hit the lava before it reaches the bottom and it’s gonna start converting all of the lava and its

Surrounding flow into cobblestone so this should impact the top of it there yep there we go and now it’s turning every single piece of lava that we had there into cobblestone including the sections which are now flowing down the site as you can see it’s creating a lovely little kind of lava fall

Cobblestone area and once we remove the water that will remain in place and you’ll notice it’s done that on both sides of this pillar it’s done that in a kind of bowtie butterfly kind of shape and has now converted a lot of that down there into cobblestone as well and that

Will form the foundation of an ever expanding mountain at this point and now with the top section of the cobblestone being a little bit higher over there it’s gonna split off in new and different directions each time meaning that every time we cast the cobblestone it’s going to end up flowing in a

Different way once the water flow has disappeared for a little bit it is safe to release the lava again because the water is going to flow away and disperse a lot faster than the lava does so at this point we can basically keep repeating this process over and over

Again and this is the point where the time-lapse is really going to kick in [Applause] Hey folks welcome back I hope you enjoyed the time-lapse and I think I’ve seen more or less all I need to see for the effects of this it’s pretty clinical it’s pretty cool I think although there are a couple of weird drawbacks to it especially while we are still trying to

Cast the inside of a mountain that I’ve already built because it is definitely not the most evenly applied process and you do have to time things a certain way to make sure that you get even coverage as you can see from that time-lapse we aren’t exactly working with a pyramid

Kind of structure the entire way down there are some sections where we had to alter the flow of lava here and there and as you can see that’s currently resting along the top side of that row of blocks over there and then coming down the site here where less

Cobblestone is formed throughout the process also there are still of course at mob spawning because the entire thing is not completely covered in lava but lava is making its way down and toasting the creepers and zombies and so on as it goes down there and I’m kind of

Enjoying seeing a few of them burn up in lava to be honest with you I’m gonna try and take out some of these mobs from up here for a minute because I’m actually kind of interested to hop down there and show you the texture that we have underneath this because while this

Obviously looks like a solid thing of cobblestone it is actually underneath the surface a little bit more holy it’s got more holes going on in there and it sort of resembles almost like a honeycomb a kind of structure in a sense it’s just kind of alternating every

Other block under the surface like that and the reason for that is fairly straightforward I mean once the lava comes down in this kind of lava fall pattern like this when the water cascades down over the top it’s creating cobblestone on the top layer of the lava so it’s effectively creating cobblestone

Over the top of where the lava block is at when lava and water meet that way they create cobblestone in the block in between them rather than creating it out or one block or the other and that’s what allows the water to continue flowing down over the top of the lava and the

Lava is just getting extinguished by the water and forming cobblestone in the block between the two of them which is really odd as an effect and if you fly through this with the camera account which I did afterwards it actually kind of got this very porous feel to it as

Though it has been created in a sort of igneous of formation kind of with air bubbles and stuff getting trapped in there of course a single block high one by one space is not gonna be enough to spawn any mobs inside so this entire structure would theoretically be mob

Proofed on the inside anyway and we wouldn’t find too much stuff getting trapped inside of there even when the game is spawning a a one block tall mob like a baby zombie it still checks for two blocks high space because it’s checking for the space in which it can

Spawn a regular zombie before it decides whether that’s gonna be a regular zombie or a baby zombie so we wouldn’t get any mobs spawning inside of there after all unfortunately I’m probably not going to cast the entire inside of this mountain today mainly because there is a large

Area down in the opposite direction which I’m not going to show you right now but I will try and get a better vantage point on yeah there we go there’s a fair amount of stuff down there which has yet to be touched by any of this lava and cobblestone and would

Be eventually if we keep piling it up but I think it might be better to create another set of dispensers over there instead because yet there’s gonna be a lot of a lot of work going into making sure all of the lava and water flows

That way and this has taken me in total I would say about two and a half hours to get this far which is not bad I mean looking at the amount of material we have here considering that that is probably about as many blocks as have gone into the outside of this mountain

In their entirety it’s almost making me wish I had done something like this to begin with except I wouldn’t have exactly got the desired effect I didn’t want to make these mountains out of cobblestone I wanted natural stone and getting natural stone is still possible with lava and water

But it’s a lot more difficult to get it in formations like this because water runs faster than lava and so you can’t create natural stone at these kind of speeds and so while I think I might continue to lava cast a little bit more of the inside of this

Off-camera I think that’s all we’re going to cover in this episode over at the Minecraft Survival Guide I do hope you’ve enjoyed at taking a look at some lava casting and maybe it’s a technique you guys can use if you want to create some quick mountains in your own worlds

For now that’s gonna be it from me and my name’s ben picks or ifs leave a like on this episode if you enjoyed it subscribe if you want to see more and I’ll see you guys soon take care bye for now
