0:15and welcome back everyone to Unreal
0:16Engine 5 beginner's guide to building an
0:18environment. In the last lesson, we left
0:21it off by creating a very basic gray
0:23box. And this time we're going to
0:25continue on working on this project and
0:27set up a landscape for our scene. So
0:30let's go ahead and get started. Within
0:32the upper left corner, we're going to go
0:34from the select mode and we're going to
0:37change it to the landscape. So let's go
0:39ahead and click on that. And then right
0:41away, we're going to get ourselves a
0:42different tab to work with. I'm actually
0:44going to go ahead and close down the
0:47content browser just so I could see the
0:48entire tab like so. And now we get
0:51ourselves a green type of an
0:53environment, a type of grid that just
0:56visualizes the type of landscape it's
0:57going to create. So right now all of
1:01this is showing us the type of landscape
1:04that we're going to create based on the
1:06type of properties that we're setting up
1:08within these settings. It's going to
1:10give us 100 by 100 scale with 63x 60
1:15quads and the number of components is
1:18going to be an 8x 8. So you see these
1:21large squares that are highlighted with
1:23the smaller squares inside. So the the
1:24large squares are going to be 8 by 8.
1:27Anyways, we're just going to keep all of
1:29the settings as in and as is. And we can
1:31actually delete the squares later on or
1:34even add them up in the future. But for
1:36now, all we're going to do is we're just
1:38going to click create. And we're going
1:41to get ourselves a sort of a landscape
1:44base for us to work with. And I think
1:46that's a nice starting point. We can now
1:49go back to the selection for example and
1:51change the way it is placed within our
1:54world. I'm actually going to select it
1:56like so. Click F and then we're going to
1:58scale out like so. And I'm just going to
2:01rotate it by holding Alt and the left
2:03mouse button and just going to bring it
2:05up just a little bit like so.
2:10So, it's going to be slightly covering
2:13up our platform. So, I'm now going to
2:16select my asset in the middle. Click F
2:18and kind of reposition my camera to be
2:20back within where we started placing
2:23this gray box for the housing. And
2:26actually even we can just select the
2:28landscape itself. And within a lock
2:31transformation, we can uh click and hold
2:34on the Z value on the blue one over here
2:36and then drag it up a little bit just so
2:38we could have it right where our
2:42platform is being positioned. This way
2:44when we're going to be building our
2:45house, it's going to position be
2:47positioned right on the very top of it.
2:49And now we're actually going to kind of
2:52start molding and modeling the entire
2:54section for this area. And the way we're
2:57going to do it is actually we need to go
2:59back to the landscape tab. So let's go
3:01on the upper left corner and select
3:03landscape.
3:05And it'll just open up uh the tab type
3:07of tab that we had previously which once
3:09we create the landscape we get. And we
3:12have three options. We have manage,
3:14sculpt, and paint. And we'll start off
3:17with the manage tab. Actually, let's go
3:19into it. And we have a couple of
3:20choices. The main ones that we need to
3:23think of are the add and delete. So, if
3:26I were to, for example, want to delete
3:28couple of settings, couple of locations.
3:30We can go ahead and select this one over
3:32here, the delete one. And then, if you
3:36were to click on the corner, for
3:37example, over here, we can delete part
3:40of the section. If we want to bring it
3:42back up, we can select add and add
3:45another section like that. And we can
3:47even add up more of the parts to this
3:49terrain. But for now though, because our
3:52main camera is going to position be
3:54positioned towards this area over here,
3:56I'm thinking that we can delete some of
3:58those uh parts from over this area over
4:00here. And then that way we'll just be
4:02saving up on the performance and just
4:04not use anything unnecessary for
4:06terrain. So just going to delete this
4:08bit over here. maybe even another one
4:12actually. Actually, we're going to leave
4:13it as is and we're just going to sculpt
4:17it out afterwards. So, right now, once
4:19we're done with that, going out of the
4:21manage mode, we're actually going to go
4:24onto the sculpt mode over here. We're
4:26going to select it. And what this will
4:28allow us to do is it allow us to shape
4:30the terrain. So, using the basic sculpt
4:32tool selected, we have a couple of
4:34options with it. and we'll just leave it
4:37as the basic brush type default with a
4:39basic fall-off. And right away, we're
4:42just going to get right into the
4:44modeling part, the sculpting part for
4:46the terrain. So, with the brush size set
4:50as uh let's say, yeah, let's go ahead
4:52and keep it as 2,00. If you wanted to
4:54make it larger, we can click and hold
4:56and then drag it to the right and make
4:57it larger. Or alternatively, we can
5:00click and hold our left mouse button and
5:01drag it downwards to make our brush
5:04smaller. And this way, as you can see,
5:06if we vis if you hover over our
5:08viewport, we can see the type of size
5:10we're going to get. We're going to keep
5:11it as a default 2,00ish. We don't have
5:14to be accurate. We can be accurate by
5:16clicking on it and just typing in the
5:18value ourselves, but we don't have to.
5:21Then the other one that we have is the
5:23brush falloff. And we're going to get
5:26that in a bit though. So, first of all,
5:28let's just go ahead and make use out of
5:30the terrain uh forming sculpt brush. So,
5:34if we were to click and hold, we're just
5:36going to raise our entire terrain
5:38upwards. And in general, if we were to
5:41want to lower this down, if we hold
5:44shift and left mouse button, we can just
5:47lower this entire terrain down. And
5:50actually, looking back now, I should
5:53probably delete the
5:56part that we had previously, the
5:57platform. So, I'm just going to delete
5:59the larger one. We're going to keep uh
6:01the smaller ones for now, the ones that
6:03we created previously. Just going to go
6:05back into the landscape like so. And
6:07now, actually, we're just going to be
6:09sculpting out a nice kind of area for
6:12where our water is going to be. So, the
6:14height is going to be kept as more or
6:16less the same for where our platform
6:18was. So, I'm just going to lower the
6:20value of the terrain so I could see
6:22barely where the terrain is positioned.
6:26And then the next part that I'm going to
6:28use is going to be something called
6:30platter. This is my favorite brush to
6:33use for having more control because in
6:35default by default the sculpt tool will
6:38just give you a lot of noise when you
6:39try to kind of um have more control over
6:42your area and that just not going to
6:44give you the type of great result. So by
6:46using a flatten tool, it'll basically
6:48pick the type of a height from the
6:51middle section of your brush. And
6:53that'll just basically apply that type
6:55of height for the rest of the size of
6:58this brush. So for example, if I were to
7:00hover over this kind of slightly
7:02downwards elev elevation of this terrain
7:06and click and hold, you can see that it
7:08flattens everything to the size of a
7:10height that I had my middle section of
7:12the brush selected. And that just
7:14creates some nice results. Alternatively
7:16though, if I were to hover over the high
7:18area and then click and hold, it'll just
7:20kind of bring the entire terrain back
7:22onto this entire kind of uh uh height.
7:25And that just helps us to have more
7:27control of how we want to have our
7:29positioned brush to be. And also, if you
7:33want to make sure that uh we don't cut
7:35off too much of this hill, we're going
7:37to make use out of the brush falloff,
7:40which if we were to lower this down to
7:42zero, it'll give us the harder kind of
7:44edges. But of course, we don't want to
7:46be too hard with the edges because it'll
7:48give us these sort of results, the
7:49artifacts. So, we never want to go uh
7:52lower than the value of let's say 2 or
7:540.1. We never want to go basically to a
7:56zero. And if we were to set this to 02,
8:00we're going to get uh somewhat of hard
8:02harder values like we did previously,
8:05but it's not going to cut off uh it's
8:08not going to give us the type of
8:09artifacts that we had before. So bear
8:11that in mind. Alternatively, if we were
8:13to set this all the way to a value of
8:16one and try to use the same kind of
8:18brush, you'll notice that we're actually
8:19going to start getting kind of a
8:22feathered off effect. And it'll
8:24basically smoon off the type of an edge
8:27for the terrain. But anyway, we want to
8:29make use out of this kind of a base that
8:32we had previously and set it up in the
8:34right kind of a height for our lake. So,
8:37what we're going to do is we're going to
8:39set up our brush just to be a little bit
8:40smaller, like so. And we're going to get
8:42ourselves a brush actually back to 0.5.
8:45I think the default one was quite fine.
8:47Then we're going to position the height
8:49of this brush to be more or less the
8:51same as we had previously. Like so. Uh
8:53to the terrain. And we're just going to
8:56basically get it to be the same kind of
8:59a height as we had this terrain. It
9:01doesn't have to be perfect. As you can
9:03see, my section for the terrain is a
9:06little bit lower than the platform
9:07itself, but that is quite fine. And then
9:10we're just going to hold our left mouse
9:12button. And just like that, we're able
9:14to shape out our entire terrain. And
9:17what we want is basically we want to set
9:20it up in a way that we have sort of a
9:23body lake over here. And we'll want to
9:27set up uh somewhat of a stream, a river
9:30coming from this area and going into
9:32this area over here. And then we'll want
9:34to have an overall kind of rundown for
9:37the water going off into the distance.
9:39So the way we're going to do it is just
9:41we're going to set up a nice location
9:43for the water like so. We're going to
9:46have actually more of an area over here.
9:50Just make sure we're not having it
9:52perfectly shaped. Of course, we wanted
9:54to have it looking more organic and
9:57whatnot. And I think that's going to
9:59look quite nice. We can even hit play
10:01and see how it's going to look like. And
10:03I think that's quite a nice depth for
10:05the water itself. I think that's going
10:07to look quite all right. So, we're going
10:09to keep it as is. So, now we just want
10:12to make sure we have sort of a let down
10:14over here for the water to go off. And
10:18we want to just have it somewhat of a
10:20straight stream going all the way to the
10:23back like so. So, by holding the flatten
10:26tool, making sure I'm always centering
10:28on the lowest area of the terrain, and
10:32then holding my left mouse button, and
10:35just shaping out this kind of a canal
10:38for the river. So, we're going to have
10:40it go all the way to the back like so.
10:42Now, for this part, we can shape it in a
10:45way that would have a somewhat
10:49of
10:50a terrain hanging out from this end over
10:52here. And we can even use this terrain
10:56that's higher up and kind of build this
10:57terrain back up like so. So that's going
10:59to look quite nice. I think that's going
11:02to look quite nice as a shape. Maybe we
11:04want to be a little bit wider over here.
11:07Think that's going quite nice. We might
11:09want to add some rocks over in this area
11:11as well for the water. It all depends
11:13how the water is going to be uh behaving
11:16within this terrain. And so far it looks
11:19quite nice. We now want to set up some
11:21hills. That's actually quite going to be
11:23quite easy to do. We're going to start
11:24off by getting a nice sculpt brush and
11:26kind of increasing this overall area.
11:29And we'll want to have one hill like
11:31this,
11:33a bit higher than this elevation over
11:35here. And then we'll actually want to
11:37have another hill that's even higher
11:39than the previous one, like so. So, now
11:41that we have two elevations to work
11:43with, we're actually going to go back to
11:44the flattened brush and we're going to
11:46be working with these types of
11:48elevations. So, we're going to be
11:49setting them up like so. But actually,
11:53we're running out of time, and I think
11:54we'll need to work on it a little bit
11:57more than before we actually continue on
11:59with designing our little house by the
12:01water. And I think for now, we're going
12:04to end it as is. And in the next lesson,
12:06we're going to continue on working with
12:08the larger scales for the terrain in
12:11order to shape this environment. So,
12:13thank you so much for watching, and I'll
12:15see you in a bit.
