Insane Blender Trick Creates Minecraft Worlds

Hello and welcome to the how to use video for the my craft world generator there’s a couple things you’re going to need for this so you’re going to want to have blender installed um in this video will be using blender 4.0.1 um but anything above blender

3.6.5 U roughly you’ll be able to use um just the same and you’ll want to go ahead and download the project from my website it’s free you can find that in the link in the description also if you haven’t seen the original video you can

Go ahead and watch that the link is also going to be in the description so let’s go ahead and dive into it so first of all when you first open it up everything is gray but you can view the textures here and display render preview and

Those will load in you’ll want to make sure that you unzip the file completely um or else the textures won’t show up and everything will be pink so if you see pink textures make sure to um unzip everything and you should be good to go um of course if you have any questions

Or comments um or any issues leave those in the comment section and I’ll do my best to help out but let’s get into it so first things first um just a couple notes on things we can do um first is if you have shift Tilda um if you press those you can

Enter this like fly View mode and that lets you use WD to move around and then shift let you speed up and so you can kind of fly around these worlds and you can also use the center scroll wheel to teleport to wherever you’re looking so teleport over to this

Pig and just jump around like this and of course we can switch back to our camera with zero uh there’s a camera here by default or if you don’t have a full number pad you can use Tilda and then View Camera so let’s go over some of these uh

Tools that you have in the side panel if you don’t see those go ahead and make sure you have the actual node setup selected if you have for example like the camera selected it’s not going to show up here so make sure you select the world that

You have and then under the modifiers tab these will show up um so you can switch back and forth between these overlays by hitting this button so if you just want to see the world without all the outlines and cameras and stuff you can hit this so

Our first option option is size so by default it’s set at 50 um you can do this all the way down to if we do one it’ll just be a tiny little World um actually zero is the smallest so a one by one um the default maximum here is

250 um but if you’d like to go above that you can hit it and manually type it in those parameters are there um for performance and just to keep the worlds from breaking but all of these even though they have set limits you can override those by just typing in any

Number especially this world size if you go much above say like 300 350 uh it’s going to take a really long time to generate those worlds because they get exponentially bigger so just keep that in mind but um you can play around with any of these settings and uh adjust them

To your hearts content but let’s go ahead and plug in 250 and it’s going to take the world uh quite a while to generate um up to a minute 2 minutes um but once it generates we’ll have a pretty stable fast running uh view of it so I’ll go

Ahead and cut to when the world actually shows up all right so now we have a much larger World um but you can see it’s running very stably um good frame rate we can actually look at the frame rate specifically by turning these overlays

On and if we just hit play here you can see it’s running out of about 60 frames per second so that’s not bad at all let’s go ahead and use that shift Tilda to fly around our world let’s teleport over to this mountain here we can see it’s quite a decently large

World size um plenty to see in the distance and of course we can fly um in this case through the floor could fly into these caves take a look around at the ores all the way down so yeah there’s a lot of exploring you can do

Um and again it runs at a pretty stable frame rate so no issues there one uh thing about world sizes is if they are large you will have to wait for the world to entirely regenerate if you mess with any of the settings so um what I generally recommend is keeping

This world size fairly small like 30 to 50 um so any world changes you made are pretty quick and they don’t take like a full two minutes every time and then once you find settings that you’re happy with then cranking the world size up to something bigger so let’s go ahead and

Bring this back down to 50 okay much faster and um we can start playing around some of these other things so squirrel X and Y let you move the world over a block at a time so just uh pretty much what it says Scrolls X or

Scrolls along on y um so you can you can even animate these values uh if you’d like so for example if we go to zero we’ll change this scroll X to Zero and then put a key frame in here by hitting this Dot and then we can jump to frame

250 and then change this to like 50 and then just so we can see it in real time better let’s just change this to a world size of 20 and then if we play this you’ll see that it’s it’s animating the scroll um so you can also animate

These it’s a lot of fun to see the world change and um all that but most of the time you’re going to have to render those out so you can see them in a reasonable frame rate because let’s see this is running at who knows yeah around five frames a

Second so they’re definitely are limits but um if you’re doing renders then um you’re going to see those results a lot better so let’s go ahead and clear those key frames just reset this to the default value you can do this by just selecting the value and then heading back space same with

This cool so one of the new features is the time this is in 24hour time so 12:00 noon um we can do say midnight 24 hours and this will spawn in Hostile Mobs so you can see like a zombie appeared here and then of course he will

Despawn when we go back today so if we go to let’s say 8 o00 in the morning he’s gone there also are special lighting for uh Dawn and and sunset so if we go to 6 uh 6 in the morning you’ll have this nice red light same with say

Say like 6:00 p.m. there’s this this Sunset lighting so um yeah you can mess around with that get some more interesting lighting and then of course have Hostile Mobs the seed I’m pretty self-explanatory just like actual Minecraft you can just type in a seed here um so let’s say like

84 and then we get a totally new world you can just click these um arrows and just you a new seed in in either direction now the stone layer height affects the Bottom Stone layer so you’ll notice there’s a top Stone layer with coal and iron and then there’s this

Layer that has the gold red stone it’s got diamond and Lapis as well and so we can move that down so for example if we go all the way to zero that layer just completely disappears and we can even go say 150 if we type that in take a while to

Generate and then we have this really tall uh chunk here with all the caves and everything and so yeah that’s quite fun to mess around with you have these caves tunneling into each other going all the way down so um yeah sweet now we have the terrain height and prom

These are both pretty similar settings that allow you to control how uh High the train is so for example if we go down to 0.5 the train is very very flat and we can go up to the max setting here is 7.5 um but of course we can make that

Even higher if we type in say like 25 and it will go go a little crazy um with these large large worlds that are uh at this point they’re kind of falling apart because there’s um there’s almost too much prominence but um you can mess around with this get some really funky

Results and part of this the reason these are showing up is because these caves are in here so if we turn these caves off this will just become stone again um but you can get some pretty neat looking stuff here so let’s reset that to the default and then this biome size changes

How big each uh terrain feature is so by default 7.9 if we go all the way up Scroll to .96 um the biome sizes become much larger now keep in mind that um they are they look quite a bit flatter like this mountain is now a lot smoother so there

There’s this lock height to size feature that um tries to compensate for that so it makes the terrain size taller as the biome size gets bigger and vice versa and so uh we can always of course manually do this so if you’d like to to manually override this

Setting um by turning it off and then we can go and change this to like 25 or something and then we get this nice tall mountain now it’s kind of hard to see this um biome size um in its fullest with with a world size that’s not very

Big so let’s change this back to 250 we’ll wait for it to generate and then um you’ll be able to see more of the biomes one eternity later all right so that took some time to generate um but here we have quite an impressive site this massive Mountain

Even got some cliffs in here um but uh yeah so this is manually overriding the large biome size with a massive terrain height and we get this absolutely huge uh mountain and so you can really get some cool stuff to show up um with just playing around with the

Settings so this is just one example of that but let’s go ahead and reset this to the more default values here so back to 50 back to default all right so now caves um you can see caves are off if we turn them on these you can completely disable them

But there’s also some settings to adjust them so first we have cave roughness so the higher this value is the more rugged the edges of the caves will be so you get more of this um like grainy texture to them but they’re smoother if this is lower we have cave

Openness and so pretty much what it sounds like the higher this value is the more open the caves are and so you get um more caves connecting to other caves um all the way down to if this is zero just get pretty much no Caves at

All and last but not least we have cave scale so as we change this scale down it opens it up um so it’s basically scaling up the individual caves um or making them smaller next we have mobs on slof so we can completely disable mobs this will also disable uh hostile mobs at

Night but we can also change how rare they are so this this value moves pretty quick so you might miss it but um all the way down to this pretty much no mobs appear but if we go to The Other Extreme then we have mobs everywhere and

So um yeah happy medium between those two mobs don’t spawn on water but they spawn everywhere else so if we change this to say like 0.5 then we can change like time to 24 so midnight and then we’ll see those hostile mobs are also multiplied back to the defaults for

Those now we also have tree Rarity which is almost the exact same thing except instead of mobs it’s trees so we can have pretty much no trees if we turn this to zero or we can have total dense forest if we go all the way up to one

Now trees only spawn on green grass so they don’t spawn on snow sand or water um but I think it looks pretty cool when you have super dense forest let’s go to say like 7 uh maybe let’s say 055 we’ll get this nice dense forest here we can fly around that

Just kind of walk around the forest it’s a little too dense to walk around but still looks cool from the outside there we go um reset that to default value and then last but not least we have grass Rarity same thing as mobs and trees just for this uh top layer of

Grass so this next next uh feature is an interesting one coal internal faces so the way the actual game of Minecraft works is if two faces touch each other they get deleted or not rendered at all basically um because if two faces are touching they’re not visible and so it

Saves a ton of rendering so the old version of the world generator each face of every Cube so all six phases would get rendered and that adds up pretty quickly and so you can imagine that um even a small world would have just tons and tons of polygons that are

Unnecessary so this coal internal faces will get rid of those faces that are on the inside so if we change our view to the inside of the world we can see that it’s Hollow actually we can especially see this if we turn caves off um this

Whole area is just empty um so this is a ton of faces that aren’t being unnecessarily rendered if we turn this on I’m sorry off if we turn this off if we turn this off you’ll notice that the um faces are everywhere so one thing to note about

This is it does take some time to calculate so um yeah if you have a large World say like 250 by 250 you’re saving a lot of polygons that blender doesn’t have to render anymore but it still has to calculate which faces are touching um

It will make the end product run quite a bit faster it will just take more time to get to that but it can be the difference between a frame rate of like 10 and a frame rate of 60 um so what I would recommend is if you’re using

Smaller World sizes like 25 um even up to like 50 the frame rate difference is pretty minimal but it’s a lot faster for changes if you have this off because it doesn’t have to calculate all those touching faces so you’ll notice if we have a world size of 20 and we use this

Scroll X it’s almost Instant versus turning coal internal faces on and there’s a lot more of a delay and that delay just gets Amplified as you get bigger worlds so just keep that in mind um not a bad idea to have this off for

World sizes of roughly 0 to 50 or 75 but anything bigger than that I definitely recommend having this on now the next feature is the netherite button and as you might imagine hitting that will convert our world into The Nether version and some of these settings work

Some of them don’t so for example um the size still works um the scroll X and Y works as well um the time does not because the nether doesn’t has the sun this seed does work um so you can regenerate the the nether just like you do the Overworld the stone layer height

Doesn’t work cuz there’s not a stone layer in the nether but we also have some settings that are unique to the nether like this nether ceiling height so this affects the um how tall this is you can get some cool results with this so if we bring it all the way

Down to Here For example then these will these layers will collide almost making this cool like cave look and of course you can bring it all the way up to say zero and then it will be quite a bit removed now the last setting we have on

Here is the nether floor Rarity this is essentially the same as just like these tree mob and grass Rarities it just affects how many of these mushrooms and fire show up so if we change this to zero nothing all the way up to one where there’s just fire and mushrooms

Everywhere so this gives a lot of flexibility a lot of control um to make these unique worlds and customize them um just a couple final notes um first of all by default the renderer is set to eeve but you can get better results if you use Cycles the lighting

Just looks better although it’s not real time so if you have this render view it’s not going to be uh quite as quick and snappy um but you’ll notice the lighting just seems more realistic uh this especially is true of the nether because um the

Lava has this um this glow to it if we switch back to EV you’ll notice uh not quite not quite the same so um depends on what you’re doing with it if you’re trying to get some cool looking renders then I definitely recommend Cycles but if you’re just messing around with the

World settings EV is probably the way to go because you have um real time rendering the default camera zero of course you can move that around so if we go to the scene here select that camera can go to the settings so if you make a

A bigger world we can change that scale to zoom in and out and of course with the camera selected we can also move it around so yeah that’s pretty much it again if you have any questions or comments leave those in the the comment section below and I’ll do my best to to

Help you out and get back to you um thanks so much for watching I hope you enjoyed and found this useful and I will look forward to seeing you in the next Video
