- [Voiceover] Let's create a simple procedural terrain.
It will be kind of a quick and dirty sculpt
and we won't have to think about it very much.
This is gonna be a very simple and easy process.
Go to the top view and dolly forward a bit
with the wheel until we're zoomed in to about 100 meters
and center the view with the right mouse button,
and create a procedural terrain.
We can do that from the object tool bar.
We've got our terrain button, we right click
on that and hold the mouse down.
We can choose procedural terrain,
with a little f next to it for function.
And now our procedural terrain is created
and centered wherever I had positioned
my camera in the top view.
Let's position the object in the world.
With it selected, go to the object properties,
numeric input, we've got the move, or position, tool.
We'll just center it in x,y, and z.
Give it a value of zero in all three dimensions.
Jump over to the size or scale
and it's defaulted to one kilometer,
we want it to be 200 meters.
Before changing this, make sure
that the lock icon is enabled.
That padlock constrains the proportions.
We'll set the x value to 200 and press enter.
Now it's proportionally scaled down.
We wanna position it a little bit lower in the scene,
going back to the move tool, or position,
and let's set it down to a value of negative 15 meters in y.
And wherever it's below the ground plane,
you'll see in our OpenGL previews, it's being cropped,
and if we go over to the top view,
we can see where the shoreline of our island will be.
We're not gonna worry much about the shape of this,
but we do want to level the elevation off.
To do that, let's go into the terrain editor.
If you've been working on your scene
for more than a few minutes, you might want to save
to a new version at this point,
before entering the terrain editor
because it does have a few issues of stability
and undo not being recognized.
So, save your scene at this point if you wish
and now let's position our view
so that the object is not visible.
Therefore, it won't attempt to update in the OpenGL preview.
I'll maximize the top view, double click
on its title bar here and use the right mouse button
to position so that we see no terrain visible,
and before we open up that terrain editor
there is one option that we want to enable
in the options, the preferences.
Go into File and Options, and we're looking for
under Display Options, View Options,
Center views on objects selected in world browser.
Let's disable that so that our view will not jump around
when we select things in the world browser.
Click okay, and with the procedural terrain selected
and not visible in the view port,
click on the Edit Object button,
and the terrain editor opens up.
First thing we want to do is to enable
the view of the scene, so we've got a button up here
and click on that to show the entire scene.
And now we can navigate in our view.
Use the right mouse button to orbit around the scene.
To position the view hold down shift
and space bar and the right mouse button all at once.
It's called horizontal pan.
To dolly forward and back use the mouse wheel,
and if you want to zoom in and out,
the field of view is control and right mouse button.
Now let's choose our brush.
I've already got Force 2D enabled,
you probably do want to turn that on
if it's not all ready on, and choose the raise brush.
And we wanna change up the settings here.
The size is a bit large.
We can set that down to a lower value, about 12 or so.
We can control that interactively in the view if we wish
and the shortcut for that is shift and left mouse button.
Bring that down to about 12 meters.
Click and drag and you see we are raising.
If we wanna push down, we can invert the operation
and the keyboard shortcut for that is v.
Now we can push that back down again.
The flow controls the strength of the effect.
We can use a very low value of about .1 or so,
and just click, have a bit more control.
And if you've got a graphics tablet,
then you want to enable pressure sensitivity
on one or more of these parameters.
I've got it turned on for the flow,
so when I use my tablet, I will be able
to control the strength by merely
the amount of pressure I apply,
and that will make it much easier for me
to quickly sculpt up this simple background landscape.
After a little bit of the raise tool,
I can switch over to the smooth tool perhaps,
and even out some of these rough areas.
That's influenced by the flow amount,
I can increase that.
The shortcut is control and left mouse button.
Just increase the flow up all the way for the smooth tool.
We can soften out some of those rough areas.
After a little bit more sculpture with the raise brush
set to a smaller radius, we wanna check our work
by disabling Show Entire Scene,
and tumble around with the right mouse button.
Check it from different angles
and make sure that it seems to make sense
in the context of a rock island.
Very good, now we can execute that change
by clicking okay in the terrain editor.
And then admire our work.
Double click on the top view, and then double click
on the main camera view so we can see
how it looks from the camera perspective,
and, of course, if we wish, we could go back in
to the terrain editor with this view enabled
and check it in real time, I just chose
not to do that for performance reasons.
