hey everybody00:00:13
welcome to today's episode of building00:00:15
worlds in unreal00:00:17
today we're going to focus on creating00:00:19
landscapes00:00:21
so the first thing that we're going to00:00:22
do is come into here in unreal00:00:25
and we're going to create a brand new00:00:26
map so i'm going to go file00:00:28
new level and in this case i am going to00:00:32
create a landscape or i'm going to00:00:34
create a map that does time of day00:00:37
all right so here i am in my new map and00:00:40
since we're going to go over00:00:41
landscapes today the first thing that we00:00:43
need to do in our new map00:00:44
is create a landscape so i'm going to00:00:47
come up here00:00:48
to the top left and i'm going to select00:00:51
modes and that's going to open up this00:00:53
little menu and i'm going to pick the00:00:55
landscape00:00:56
mode now at this point we haven't00:00:59
created anything yet this green00:01:01
grid that we see is a preview that's00:01:05
going to show us what we will be00:01:06
creating once we hit the00:01:08
create button right here so unreal gives00:01:12
us the opportunity to00:01:13
experiment with this with the size and00:01:16
divisions of the landscape00:01:18
before we create it a landscape is a00:01:21
large uniform00:01:22
grid of vertices each vertex represents00:01:25
a00:01:26
point on the landscape when creating a00:01:29
new landscape00:01:30
unreal assumes that we want a vertex00:01:33
density of one vertex per meter00:01:37
so as you adjust the settings it keeps00:01:39
this spacing00:01:41
if you want to control the grid density00:01:43
the only00:01:44
control that you have at this stage is00:01:46
the scale00:01:47
setting here i recommend that you leave00:01:51
the scale alone for now00:01:52
we'll stick with one vertex per me per00:01:55
meter for now and adjust it later00:01:57
after the grid is created i'll show you00:02:01
that in a minute but for now just keep00:02:02
in mind that every grid square here00:02:05
every little green00:02:06
square that we're looking at is one00:02:08
meter00:02:10
and here at the bottom where it says00:02:11
overall resolution00:02:13
that is the size approximately00:02:17
in meters that we're going to create for00:02:20
our grid00:02:22
so let's zoom out here a little bit now00:02:24
for efficiency00:02:25
unreal breaks the grid into sections and00:02:28
components00:02:30
a component is the largest unit of the00:02:33
grid00:02:34
and you can see the components here00:02:35
outlined in this bright green color00:02:38
the actual quads or00:02:41
individual little squares00:02:44
use the dark green but the components00:02:47
are outlined in00:02:48
light green each component has a cpu00:02:51
cost to render so you can make your00:02:54
landscape more efficient by reducing the00:02:56
number of components you use00:02:58
one method for reducing the number of00:03:00
components is to control the component00:03:03
number directly00:03:04
so here we see number of components and00:03:07
i've got eight00:03:08
and i can increase it and decrease it00:03:10
but you can see that as i change this00:03:12
value00:03:13
the actual size of the landscape is00:03:16
changing00:03:17
so if i set this to 4x4 in order to00:03:20
reduce the number of components00:03:22
now i also also have only a quarter00:03:25
of the available landscape size that i00:03:28
did before00:03:29
what if i want to keep the landscape the00:03:31
same size but00:03:32
still reduce the number of components00:03:35
that's where this00:03:37
section size comes in and00:03:40
sections per component can also help00:03:42
with that00:03:44
so by default we have one section per00:03:47
component00:03:48
but it's also possible to change this00:03:50
setting00:03:51
so we'll have four sections per00:03:53
component if i drop this down and pick00:03:55
two by two now you can see that our00:03:58
components are split00:04:00
up and divided so that there are four00:04:03
sections in each component you can see00:04:05
that a section is outlined kind of by00:04:07
this00:04:08
medium green color our components are00:04:11
the light green color00:04:12
and our individual quads are the dark00:04:14
green color00:04:17
so and i don't know if you noticed but00:04:19
when i switch back and forth00:04:20
forth between one section per component00:04:23
and00:04:24
two or four sections per component it00:04:26
now doubles the size of my landscape00:04:29
so whereas before i had eight components00:04:32
by eight components and one00:04:34
section per component if i choose00:04:38
two sections per component it doubles00:04:41
the size00:04:42
and now i can reduce my components down00:04:45
to four by four and get the same size of00:04:48
landscape00:04:49
so i used to have 64 total components00:04:52
and now i just have 16 but i have the00:04:55
same landscape00:04:56
size and that's going to help me save on00:04:58
some cpu costs that's a really nice cost00:05:00
savings there00:05:02
another control i have is this section00:05:04
size here00:05:05
it defaults to 63 by 63 quads per00:05:09
section00:05:10
and this controls the number of quads or00:05:12
grid squares that we have00:05:14
in each section since the quads are set00:05:17
to one meter size00:05:19
increasing this will set the size of the00:05:23
section00:05:24
instead of increasing the quad density00:05:27
i'm going to double this value from 6300:05:30
up to 12700:05:32
and notice that my landscape doubled in00:05:34
size again00:05:36
and now to keep it the same size i can00:05:39
either switch my sections back to one00:05:41
section per component00:05:43
or i can reduce my number of components00:05:46
down to00:05:47
two by two and now00:05:51
after increasing the section size00:05:54
and decreasing the number of components00:05:56
i've got the same size00:05:58
landscape but i've reduced the total of00:06:00
numbers00:06:01
the total number of components down to00:06:04
four00:06:05
so you might think that i just want to00:06:07
set my components down to00:06:09
one00:06:12
and then set my quad size up to00:06:16
256 or 25500:06:19
and now i only have one component00:06:21
overall00:06:22
um and i have the same size landscape so00:06:25
this will create the lowest cost on the00:06:27
cpu00:06:28
but there is a downside to having large00:06:31
sections00:06:32
when you're playing the game as you get00:06:34
further away from00:06:35
a section unreal will reduce its quality00:06:39
to save performance on the gpu00:06:42
larger sections don't reduce as well as00:06:45
smaller ones00:06:46
so a large section will cost more on the00:06:49
gpu00:06:50
than a small one the challenge is to00:06:52
find a combination of component count00:06:54
and00:06:55
section size that's a balance between00:06:58
cpu and gpu cost00:07:02
a good rule of thumb is to make sections00:07:05
larger00:07:06
on larger landscapes and make them00:07:08
smaller00:07:10
on smaller landscapes now luckily for us00:07:14
epic has created a really nice table in00:07:17
their documentation00:07:18
that has a nice set of optimized00:07:20
settings for many different sizes of00:07:22
landscapes00:07:23
so here you can just pick the size of00:07:26
the landscape that you want in this left00:07:28
column00:07:29
and then it has all the rest of the00:07:31
settings already outlined for us00:07:34
so we don't have to figure out and do00:07:35
all the crazy balancing between cpu and00:07:38
gpu00:07:39
we can just use the settings that00:07:40
they've already come up with00:07:42
so let's jump back to unreal00:07:45
and we're going to go ahead and use the00:07:47
default setting of00:07:49
63 quads uh one00:07:53
section per component and eight by eight00:07:56
components and that's going to give us00:07:58
a terrain or a landscape that's roughly00:08:02
half a kilometer by half a kilometer now00:08:05
you might be saying00:08:06
oh heck no i want to jump in and create00:08:08
an eight kilometer by eight kilometer00:08:10
train and just make this huge amazing00:08:12
awesome world well what i recommend00:08:16
is that we start out small and create a00:08:19
couple of little landscapes00:08:22
and then move on to something bigger and00:08:24
this is kind of like creating a bunch00:08:26
a bunch of thumbnail drawings before00:08:29
painting the ceiling of the sistine00:08:31
chapel00:08:32
so once you've done several little00:08:34
practice areas00:08:36
you can take what you've learned and00:08:37
make something huge00:08:39
so we're going to stick with the default00:08:41
settings of 63 by 6300:08:44
one section per component and eight by00:08:47
eight components with an overall resolution of00:08:51
505 by 505 and now00:08:54
all we need to do is hit the create00:08:56
button00:09:00
and unreal just built a beautiful00:09:02
landscape for us00:09:04
now i'm going to zoom in back here to00:09:05
the center of the map00:09:07
and you can see that our initial little00:09:11
square that we had created is kind of00:09:13
buried under the terrain00:09:15
in order to fix that i can00:09:18
go back to select mode select00:09:22
our landscape and we're just going to00:09:26
move our landscape down to zero00:09:29
instead of 100 and now our initial00:09:32
little cube00:09:33
is no longer buried all right let's talk00:09:36
about00:09:37
vertex density or landscape resolution00:09:40
for a minute00:09:41
i'm going to switch over to wireframe00:09:44
mode00:09:45
and you can see that now we can take a00:09:48
look at the00:09:49
density of our terrain00:09:53
and right now the landscape is sent to a00:09:55
density of00:09:56
one vertex per meter and this might work00:09:59
well for some things but what i really00:10:02
like to do is increase the density00:10:04
so that we can have more details so that00:10:06
when we're sculpting our terrain00:10:08
so that when we're painting our00:10:10
materials we can make changes00:10:12
more frequent than just once per meter00:10:15
and so the way that we can do that is00:10:17
come up here to modes00:10:19
go back to landscape select the manage00:10:23
tab and then come here to the resize00:10:26
button and now this will make00:10:29
allow us to change the the layout of our00:10:32
landscape00:10:33
without actually having to delete the00:10:37
landscape and start over00:10:39
so here i have section size and i've got00:10:42
my section size set to 63 by 63.00:10:45
now before i created the landscape when00:10:47
we were looking at that nice green00:10:49
grid if i were to change this section00:10:52
size it would actually00:10:53
increase the size of our section00:10:57
but now what i can do is increase this00:10:59
section00:11:00
size and instead of increasing the size00:11:03
of the section00:11:05
as long as i have resize mode set to00:11:07
resample00:11:09
this is going to increase the density00:11:12
of the section here so i'm going to go00:11:14
ahead and hit apply here00:11:17
and you can see that now i have00:11:19
significantly00:11:21
more detail on my landscape00:11:26
now you might be saying oh man that is00:11:28
just totally gonna kill the performance00:11:31
and you're right uh in in normal00:11:34
situations especially if i look off here00:11:36
toward the horizon00:11:38
that is an incredibly dense landscape00:11:40
and i wouldn't want to do that00:11:42
and so what i'm going to do is in order00:11:44
to make up for the increase00:11:46
in density close to the camera00:11:49
i'm going to reduce the amount of00:11:51
density that i have that i have00:11:52
further away so the way that we're going00:11:55
to do that is i'm going to go ahead and00:11:56
select00:11:57
my landscape and i'm going to come over00:12:00
here to00:12:01
my log distribution settings and these00:12:04
are the settings that i have to control00:12:07
the way that my detail falls off as i00:12:10
get further away from the landscape00:12:12
let's just zoom out here and you can see00:12:14
that as i get further away00:12:17
unreal reduces the density of the detail00:12:20
the00:12:22
the quads actually change00:12:25
so that it's drawing fewer quads as i00:12:27
got further away but00:12:28
with our current settings you can see00:12:30
that our landscape is still00:12:33
really dense i have way too many00:12:36
vertices00:12:37
here for the distance that i am00:12:40
so i'm going to go ahead and adjust00:12:42
these settings00:12:43
to reduce the amount of density00:12:46
at this distance so first i'm going to00:12:49
change my00:12:50
log0 screen size from 0.500:12:54
to 1.5 and you can see that my density00:12:58
was reduced00:12:59
now i'm going to set my lot 0 setting00:13:02
from00:13:03
1.25 down to 100:13:06
and again the density is reduced some00:13:08
more and i'm going to set my00:13:10
other lods from 3 down to00:13:13
1.7 and now you can see that i have00:13:16
significantly less detail00:13:19
here when i'm further away but00:13:22
more detail is added in as i get closer00:13:25
and closer00:13:26
until finally when i'm as close as i00:13:28
want to be up00:13:30
up here i'm getting that four verts per00:13:33
meter00:13:34
that i really want that really tight uh00:13:36
detail close up00:13:38
but as soon as i move back you can see00:13:41
that the detail is removed00:13:44
and i'm able to get a nice balance00:13:46
between tight detail00:13:48
up close and less detail00:13:51
further away which is exactly what i00:13:54
want00:13:55
in games when you're troubleshooting or00:13:58
when you're trying to increase00:13:59
performance00:14:00
what you want to do is to be able to00:14:02
give the player00:14:03
a lot of really nice detail close up but00:14:06
get rid of that detail00:14:08
further away where it can't be seen so00:14:10
that's what we've done here00:14:12
and so now we're going to be able to00:14:14
paint uh we're going to be able to00:14:16
sculpt our cur terrain00:14:18
and paint our materials with a lot of00:14:21
tight detail close up00:14:22
and the detail will be removed for us by00:14:25
the game engine00:14:26
uh when we get further away so that's a00:14:28
pretty cool feature00:14:32
all right the next thing that we want to00:14:33
do is talk about sculpting00:14:35
the terrain but before we get too far00:14:38
into that i want to come up here and do00:14:40
file save current as00:14:44
and i'm going to give our map a name00:14:46
just so that we can save it right now so00:14:48
i'm going to name this00:14:49
my my new map00:14:54
and we'll go ahead and save that now00:14:56
what i want to do is switch back00:14:58
to the other map that i was working on00:15:00
and this is the example00:15:02
this one's called uh landscape test00:15:05
and we're just going to take a look at00:15:06
this really quick and so i want to show00:15:09
you what we're going for so here's a00:15:11
little00:15:12
creek that i created and basically this00:15:15
is just00:15:16
a little depression in the landscape00:15:19
with a nice little creek flowing through00:15:22
it and this is the goal this is what we00:15:23
want to create00:15:24
so i wanted to take a look at this and00:15:26
show you and then we can00:15:29
jump back into our map and do something00:15:31
similar maybe even a little bit better00:15:33
than this we'll see00:15:35
the other thing i want you to notice is00:15:37
that i have this mannequin character00:15:39
standing here00:15:40
and the reason that i have him in my00:15:42
scene is just for scale00:15:44
scale is something that's really00:15:45
important and so when we jump back into00:15:48
our other map i'm going to add this00:15:49
mannequin00:15:50
into that scene so that we can see how00:15:52
big things are00:15:54
if we don't have something that is00:15:57
recognizable as an everyday object it's00:16:00
really hard to know00:16:01
how big and small we're making things00:16:04
and so it's important to have this guy00:16:05
in here or something else that we know00:16:08
the actual size of so that we have00:16:11
everything so that we have something to base the00:16:13
size of everything else on00:16:15
so let's switch back to our other map00:16:20
and we'll go ahead and add our mannequin00:16:22
in00:16:23
so i'm going to come it down here to the00:16:25
content browser at the bottom00:16:27
and i have this folder called mannequin00:16:30
characters00:16:33
meshes and here's my sk mannequin so i00:16:36
can just drag him into the scene00:16:38
and you can see how the mannequin is a00:16:40
little bit smaller than maybe that you00:16:42
thought the scene was00:16:44
and that's because this render ball here00:16:46
is actually much00:16:47
larger than you probably thought so now00:16:50
with the mannequin in the scene it's00:16:51
really easy to see00:16:53
how big i need to make my stream so like00:16:56
i said it's important to have this real00:16:58
world reference00:17:00
so that you know how big and small to00:17:02
make things in your scene if you don't00:17:04
have the mannequin folder here00:17:06
you can come here to add new and then00:17:10
add features or content pack and just00:17:13
pick the00:17:15
third person and this will include the00:17:18
mannequin character00:17:20
so once you hit add then you'll have a00:17:22
mannequin folder here and you can add00:17:24
that00:17:27
all right so let's jump into sculpting00:17:28
terrain i'm just going to zoom out here00:17:30
to give myself a little bit more space00:17:32
and we're going to come up to modes00:17:34
landscape00:17:36
and then click on this sculpt tab00:17:39
and now what this gives you access to is00:17:41
a whole bunch of00:17:43
tools for controlling the shape of your00:17:46
terrain00:17:47
we're going to start out by talking00:17:48
about the sculpt tool what this allows00:17:50
you to do00:17:51
is to raise and lower the terrain00:17:54
so i'm going to pick sculpt and you can00:17:56
see that i have this white circle here00:17:58
this white circle shows me what parts of00:18:00
the landscape i'm actually going to be00:18:03
influencing when i paint so if i click00:18:06
and drag00:18:07
you can see that it's actually raising00:18:10
parts of the terrain and the more that i00:18:14
paint on this the higher that gets so00:18:18
you can see that i've made a nice little00:18:20
hill for my mannequin guy now00:18:23
and i'm raising the terrain what if i00:18:26
want to lower the terrain i can use the00:18:27
same sculpt00:18:28
tool and just hold down the shift key00:18:31
and that will lower the terrain00:18:35
so now i'm kind of pushing down the hill00:18:38
that i created00:18:41
and over here on the left i have00:18:43
controls that control00:18:45
my brush so this is how much power i00:18:48
want to put behind it so if i00:18:50
turn this way up and then sculpt you can00:18:52
see that00:18:54
now when i raise the terrain it's00:18:56
raising it a lot more00:18:59
i can also control my brush size so00:19:01
right now my brush is set00:19:03
to 5 meters but i can reduce it00:19:08
so if i want to create something that's00:19:11
even smaller than a meter00:19:13
i can set my brush size really small00:19:20
and also here is my brush fall off so00:19:23
this is kind of the softness you can see00:19:24
that00:19:25
right now the white circle in the middle00:19:28
there has a nice little fall off at the00:19:30
edges00:19:33
but if i turn the follow-up all the way00:19:35
up to one it's even00:19:36
softer and if i turn it down to zero now00:19:39
my brush has a really00:19:40
hard edge and it's going to create00:19:43
really sharp00:19:44
features so it's really nice to be able00:19:46
to control00:19:48
uh the settings of the brush like this00:19:49
to create smooth00:19:51
brushes or hard brushes and also to be00:19:54
able to control the00:19:56
the size of the brush that you're using00:19:59
to paint on your terrain00:20:03
all right so we've got a tool that00:20:05
raises it00:20:06
and we've got a and if we hold shift we00:20:09
can lower it00:20:11
what if we want to get rid of what we've00:20:13
done00:20:15
we have kind of messed up our terrain a00:20:17
little bit here00:20:18
and for that we have the flatten tool00:20:20
and what this does is00:20:22
wherever i click first it's going to00:20:24
take that height00:20:26
and it's going to paint that height00:20:27
across wherever i stroke the brush so00:20:30
if i click here in a flat area and then00:20:33
paint00:20:34
here across the areas where i've already00:20:37
painted00:20:38
you can see that i'm getting rid of what00:20:40
i did before00:20:41
it's kind of like using an eraser if i00:20:44
click00:20:45
here in the flat area then it brings00:20:48
everything up to that level and it also takes00:20:51
things00:20:52
down to that level so if i00:20:55
sculpt something kind of high here and00:20:57
then i go to00:20:58
flatten and click here where it's flat00:21:01
and then00:21:02
go across that it will reduce that00:21:07
that big large kind of bumpy mountainy00:21:09
area to the flat that i've selected00:21:12
just the same if i have a large bumpy00:21:15
area00:21:16
and i pick flatten and i click first in00:21:19
that area it's going to flatten00:21:20
everything00:21:21
up to wherever i clicked first00:21:24
so this is nice if you if you have kind00:21:27
of a mountainy area and you know there's00:21:28
going to be some combat00:21:30
in in a specific spot and you need to00:21:32
kind of level out that area so that00:21:35
it can be open for some gameplay to take00:21:38
place you can use this nice flatten tool00:21:46
i'm just going to go ahead and go over00:21:48
my terrain and just kind of flatten00:21:50
everything out here so we can get back00:21:51
to00:21:52
what we had before all right if you have00:21:56
some nice rolling hills and soft smooth details00:22:00
let's just go ahead and add some some00:22:03
soft smooth details here and this is looking00:22:06
like00:22:07
a little bit too smooth and soft00:22:11
you can use this noise tool to go ahead00:22:14
and bump things up00:22:16
so i'm just going to zoom in here so00:22:18
that you can see a little bit better00:22:19
what it does but right now00:22:21
these these rolling hills are kind of00:22:23
smooth00:22:24
but if i click on noise you can see that00:22:27
it's just gonna kind of rough things up00:22:30
and add in some more uh noisiness to my00:22:33
surface it's kind of00:22:35
uh adding crazy bumps and ridges and00:22:38
things00:22:40
and so this is a good way to add00:22:43
additional tight detail00:22:45
there's all kinds of controls over here00:22:46
to change the scale00:22:49
and the size of the noise which is00:22:51
pretty cool00:22:52
the opposite of the noise tool is the00:22:54
smooth tool00:22:56
so if something is too rough and bumpy00:22:59
you can use smooth tool to kind of00:23:02
soften it out00:23:03
and you can see that it just kind of00:23:06
melts everything00:23:07
and gets rid of noise i'm going to00:23:10
reduce the strength of this a little bit00:23:13
so they can get a better idea of what's00:23:14
going on so if i just go00:23:16
over this you can see that that tight00:23:19
noise that used to be there00:23:21
uh is completely going away00:23:25
so i'm just going to kind of smooth00:23:26
things out00:23:28
and it just averages whatever you're00:23:31
painting with whatever00:23:33
is around it so it removes really tight00:23:36
detail00:23:37
and leaves you leaves you with the broad00:23:40
overall00:23:41
uh smooth detail00:23:45
so there's some really nice controls00:23:46
there for painting terrain00:23:53
you're able to get the the look that you00:23:56
want00:23:59
with sculpt smooth00:24:03
and noise now there's some other tools00:24:06
here and i'm going to post a link00:24:08
in the description to the documentation00:24:11
that unreal gives so that you can go00:24:13
ahead and take some homework for yourself and play00:24:16
around with what these other tools do00:24:18
ramp erosion hydro00:24:21
etc but for now00:24:24
what we need to do is make our little00:24:26
creek so i'm going to come over here00:24:28
just to give myself a little space00:24:31
and i'm going to pick this sculpt tool00:24:34
and maybe increase the tool size just a00:24:37
little bit00:24:40
and we want to make our uh creek kind of00:24:43
an indention so i'm going to hold down shift and kind00:24:46
of paint along here maybe00:24:48
curve it around00:24:53
so we're going to make a creek kind of00:24:55
flowing through00:24:57
the landscape here and i'm just going to00:25:00
kind of keep00:25:01
painting00:25:06
[Music]00:25:08
and curve it just a little bit00:25:15
[Music]00:25:17
so this creak's going to be a little bit00:25:18
longer than the other one that i created00:25:22
just kind of00:25:26
keep painting to indent this creek00:25:30
into our landscape and now i'm going to00:25:33
paint without holding shift i'm just going to00:25:35
raise up the00:25:37
sides around the creek a little bit00:25:46
just to make it feel a little bit more00:25:49
natural00:25:51
maybe lower this part here00:25:59
and then raise up the banks a bit00:26:11
all right that's not too bad now maybe00:26:13
i'll use the smoothness tool just a00:26:15
little bit00:26:16
i'm gonna switch over to smoothness00:26:19
and i'm gonna turn the tool strength00:26:23
down quite a bit because i just want to00:26:25
smooth out00:26:27
the the largest details i'm going to00:26:30
shrink my brush down as well00:26:34
so i did get a little bit of noisiness00:26:36
in here and i want to get rid of some of00:26:38
that so i'm just going to go over it00:26:40
with the smoothness tool00:26:42
to kind of smoothen it out00:27:00
one thing that i forgot to mention just00:27:01
kind of while i'm doing this is00:27:04
when you first create a landscape unless00:27:06
you provide it an initial material00:27:09
the landscape is going to come with this00:27:12
nice gray checkerboard on it00:27:14
and in future videos we're going to be00:27:16
talking about creating a landscape00:27:18
material in fact i think that's what00:27:20
we'll dive into00:27:21
next week unless you guys have some00:27:24
major questions about00:27:25
sculpting terrain i think we're just00:27:27
going to go ahead00:27:28
and start talking about landscape00:27:31
materials00:27:32
next week and that topic is a little bit00:27:35
complicated and so it'll probably take00:27:36
us00:27:37
a couple of weeks to get through it but00:27:39
we're going to do some cool things like00:27:41
i'm going to show you how to00:27:43
uh download some materials from00:27:47
from quixl mega scans and how to format00:27:50
the materials and how to optimize them00:27:53
and we're going to go over several00:27:54
different techniques for getting rid of00:27:56
uh tiling in the distance on the on the00:27:59
landscape00:28:00
so that's going to be pretty cool i00:28:02
think we've got a pretty decent00:28:04
riverbed here00:28:08
one thing that i do want to mention00:28:10
about landscapes is a lot of people00:28:12
make landscapes using height maps and00:28:15
that is a00:28:16
really good idea to download00:28:19
heightmap data from from geological00:28:23
surveys there are a lot of different00:28:26
sites available on the internet where00:28:27
you can get real-world height map data00:28:30
and that's really cool you can actually00:28:32
bring in real world00:28:34
topology data from the earth and apply00:28:37
it to your landscapes in unreal00:28:39
that's something that we're going to go00:28:40
over in a future episode00:28:42
for this section of the tutorial where00:28:45
we're talking about building the creek00:28:47
we're just going to go ahead and stick00:28:49
with the height maps that we've painted00:28:52
but in a future episode we're going to00:28:53
talk about how to bring in00:28:55
height maps from real world data and00:28:58
create00:28:59
uh terrain that that actually mimics00:29:01
real world places so00:29:03
that's gonna be that's gonna be a neat00:29:04
episode i hope you're looking forward to00:29:06
that00:29:07
the last thing that we're gonna do today00:29:09
is actually play the game that we've00:29:11
started00:29:12
to create so i'm going to come up here00:29:14
to world00:29:15
and we're going to pick world settings00:29:18
and under game mode override we're going to00:29:21
pick third person game mode00:29:24
now if i come up here and i press play00:29:27
you can see that we've got our little00:29:29
mannequin in our scene and i've started00:29:31
out00:29:32
on my beginning platform but i can use00:29:36
third person game controls w to move00:29:39
forward as00:29:40
i hold down the right mouse button to00:29:42
look around00:29:43
and i can run my mannequin around my00:29:45
scene00:29:47
and i can jump with the space bar and00:29:49
you can see00:29:50
that here is the little stream bed that00:29:53
we created00:29:55
and you can get a good idea for how big00:29:58
this area is by running around with your mannequin00:30:02
now this is important00:30:04
because if you create something that's00:30:06
too large or too small00:30:08
uh and like for right now i can see that00:30:11
i've made this kind of too00:30:12
deep so i'm probably gonna go and go00:30:14
ahead and fix this before the next00:30:16
episode00:30:17
but my mannequin is kind of stuck down00:30:20
here in my stream bed00:30:22
and i want to play test this as i'm00:30:25
going along even at this really early00:30:27
stage00:30:28
so that i get the terrain or the00:30:30
landscape the right00:30:32
shape for uh for my player00:30:37
so it's really important that as you go00:30:39
along each step of the way that you're00:30:41
play testing to make sure that00:30:43
your landscape is doing what you need it00:30:45
to and especially that things are the00:30:47
correct00:30:48
distance away if you create a game where00:30:51
your player has to just00:30:52
run forever uh in a direction the player00:30:55
is going to get really bored so00:30:57
you want to make sure that you're00:30:58
jumping in here with your mannequin00:31:00
and play testing your game so that you00:31:03
can ensure that you're getting00:31:05
a good balance between uh things being00:31:08
really far apart and not00:31:10
making your player really bored as00:31:11
you're running around00:31:13
all right like i said next week we're00:31:14
going to talk about starting to create00:31:17
materials for our landscape so i hope00:31:18
you come back for that00:31:20
be sure to hit the subscribe button if00:31:22
you haven't already and we'll see you00:31:23
next week everybody00:31:36

byeDescription:
Landscapes are the foundation of your world in Unreal Engine. In this episode, we go over how to create a landscape. We go over all of the settings for tuning the landscape performance, vertex density, and distance detail reduction. Then we go over the tools that Unreal provides for sculpting the landscape - including Sculpt, Flatten, Noise, Smooth, and more. Finally, we sculpt a small stream bed to begin the process of creating our forest scene that we went over last episode. What, you haven't seen the previous episode?
