SPEAKER: Hi, everyone. Welcome to this new
Twinmotion tutorial. In today's video, we
will be looking at how to add vegetation to your project. Let's start by the basic. Let's cover the simple drag-and-drop. I will come to my vegetation folder-- trees-- and I will simply drag
and drop an asset from the library inside my scene. When I'm releasing my mouse, that
object is added to my project-- pretty basic. [MUSIC PLAYING] What you can also do
is use the multi-drop. Here, I'm going to click one time
on my object and release my mouse. And once I've done that, now
this object is under my mouse. And now, at each time, I'm
going to click in my viewport. This will add a D
object to my C So it's a quick way to add some trees or some
vegetation assets to your project. You can also use the multi-drop to
place down a selection of assets. So here, I'm going to
select the Norway spruce. I'm going to press Control
on my keyboard, click on the Austrian pine. And let's say, also, I want
maybe to add that Koyama spruce. So here, I've selected
three different trees. Now they are all under my
mouse, and at each time, I'm going to click in the viewport. Twinmotion will randomly
select one of them, and it will add it to the project. [MUSIC PLAYING] So it's a quick way
to add more variation and randomness to your project. When you add a tree from the
library to the viewport, by default, it's added at its medium age. But each tree introduction
comes in three different age, so let's have a look at that. So here, I'm just going to
place the same tree three times. The one on the left-- I'm going to select him. And on the right, in
the property panel, here, the first option
we can see is the age. So here, we can play with
the age of that specific tree that I have selected. I'm going to lower
the age of this one. I'm going to select
the third one, and I'm going to raise the age of that one. And here, as you can see,
it's really the shape of the tree that has
evolved over time. It's not just a basic scale. We can really see that that
Norway spruce started pretty young with that shape. Then it will get thinner, and
we have some branch a bit over. But the adult version that is most
likely to grow inside the forest lost some of the branches and leaves
towards the bottom of the tree trunk, to have more
foliage towards the top. So as you can see here,
it's really the evolution of the tree across several years. In the property panel, we have
other options-- like, here, we can change the season. This specific tree doesn't have any
season because it's a pine tree. Let's have a look,
maybe, at an apple tree. So here, I'm going to type, apple. I'm going to drag and
drop that apple tree. [MUSIC PLAYING] So here, as we can see, we have
some apple growing on the tree. Let me select it. I can switch to the summer
version, autumn, and winter. In the details, there are
even option to customize the color of the leaves,
the bark, disable the growth, that we are
going to cover a bit later, and finally, disable the wind. [MUSIC PLAYING] Often, the position of a tree
is defined in your CAD software. So here, in the My Viewport,
you can see some white box. It's the folder that I have in my
scene graph called Tree Placeholder. In that case, that tree
came from my CAD software. I created a basic box, a
dummy, to position the tree where I wanted them, precisely. And now, in Twinmotion, I
can replace them all at once by some Twinmotion 3D trees. So what I'm going to do here
is click on Select My Folder. I'm going to right-click on it. I'm going to click on Replace Object. This open that property panel,
the Replace Object panel. Now what I'm going to do is search
for the tree I want in my project. Let's say, for example, this tree is
supposed to be an Indian sandalwood. I'm going to drag and drop
that tree in that dropbox, and I'm going to click
on Start Replacement. This will replace, automatically,
all the box, all the dummies by that Twinmotion tree I
have added to the folder. And because it's a tree, you
take a random color variation and a random scale, just
to break up a repetition. So as you can see here,
now we have those tree that has been placed in the exact
correct position defined by my CAD software. While adding trees one
by one is pretty cool, you can precisely place
the object where you want. You can also use the Paint tool to
populate a large area very quickly. So here, I will come to the Populate
dock at the bottom of the screen. I'm going to click on Foliage,
and I will start with the Painter. Here, same idea. I have a dropbox that
I can expand, and I will need to drop a set
here to start painting them. So here, let's say I want to paint
the same tree, so the Norway spruce. I'm going to add that tree once. I will select my brush,
and now I can start to paint my tree on my terrain. When you use the Paint
tool, it creates a layer that you can then edit afterwards. The layer is defined by
those small green triangle that you can see on screen right now. If you don't want to
see them, you can just press G on your
keyboard to hide them. So now that my layer
has been defined, I can then further customize it. So let's say I want to add
a new tree to that layer. I can simply take my Austrian
pine and add it in my dropbox. This will scatter that new tree
on my layer that I have set up. Now, let's say I actually don't
want that much Austrian pine. I can select that
specific tree species, and I can lower the
density of this one. You can also change the scale of
one specific tree in that property panel. So let's say that the
Norway spruce here-- I want, maybe, this one
to be at an adult age. a I'm going to the age slider,
and I'm going to grow this one. Let's say, maybe, in that forest,
there is the same tree species but in different age. I can drag and drop, another
time, the Norway spruce inside that dropbox. That second time, here,
I will leave him at 50%, and I will add him a third time. And this one-- I'm going
to make it a young version. So here, we have, three
time, the same tree-- one at an adult age, one at a
medium age, and one at a young age. Even after that, I can customize
the density of each tree. So for example, if I want
to have more adult variant, I will select the adult, and I will
just raise the density of this one. Let's say, now, I want a slightly
a larger area so I can paint more. I can obviously also change
the diameter of my brush. But now what I want to do is add a
bit of ground cover in that forest. So let's come back in the folder. Let's start, maybe, with
some rocks, actually. To add a new asset, Same thing I will
drag and drop it in that dropbox. Here, there is a bit too much
rock, so I will select my rock and just lower the density. I'm going to do the same, maybe,
with that smaller one here. Same thing. I can change the density. Maybe a third one-- that one. Yeah, something like that. Let's say that now I
want to add some bushes. I will come to my vegetation--
bushes, and same thing. I can drag and drop some vegetation
asset in the folder like that. Those bush here looks a bit
too bright for the forest, so what I'm going
to do is select one. I will come to the Details, and I
can change the tint of that one. Also, if I want to change the color
of the fern on all of them at once, I can simply select all of them
and edit the color of all of them at once. In my Paint tool, I can
also add some grass. So let's get a bit
closer to the ground. And here, I will come
to the Grass folder, and we can maybe add
some dry, wild grass. So here, it's scattered
all around-- some grass, so we don't even see
the ground anymore. So it's a quick way to make your
terrain look way more realistic and add details to it. As you can see here, just a couple
of clicks, and a couple of-- let's say-- one minute
with all the speaking-- I've really vitalized that whole
area in front of our project. While the Paint tool can be used
on a really large area like that, it can also be used on
some smaller spaces. Let's come closer to our project
to show you another example. We'll come over here, and I
will come back in my folder, to the Misc folder. Here, we have some ivies. So ivy-- you can use some one
at the bottom of the folder that you can place down
manually, one by one, like that. Yeah, I can have some
coming from the ground. That's the growing ivy. We have some that fall. That's the falling ivy. So here, you can place
something like that, but you can also use the
Paint tool to paint some ivy. So what I'm going to do now is
come back to the Populate panel. I'm, again, in the Paint tool. And here, I want to
use the brushable ivy. I'm going to drop that one here. I will select my
brush, and I will just set up a really small diameter--
something like 0.2, maybe. I will come closer to my project. And now I can start to paint
that ivy directly on my building. Obviously, on that
specific project, it's not perfectly suited to have
some Ivy growing on the glass, but just to give you the idea. So here, I'm just, again, painting
exactly where I want that to ivy. So it's a really
quick way to visualize some pieces of your project. [MUSIC PLAYING] So now that we covered
the Paint tool, let's have a look at the
Scatter tool, going back a bit so we can have a big
picture of our projects. We'll come to the Populate tool. And actually, before using the
tool, I want to show you something. Here, I will click somewhere
in my viewport to select, for example, that mesh. When using the Scatter tool, it
will scatter the selected object on the geometry you
will be clicking on. Let's just raise that
mesh above the terrain so we better see what will be
happening in that part of the video. So now what I'm going to do is
come to the Populate, Vegetation, Scatter. I'm going to drag and drop the
Norway spruce in my dropbox. With this tool, I need to select
the asset I want to add to my scene, and I will need to click on my
Scatter tool to activate it. Now that my tool is
activated, where I will click, it will start to add
the selected object. So here, once I start
to click on my mesh, it will add the trees on to
that geometry and nowhere else. Let's say I want to add it to
that piece of the terrain-- so as you can see here,
it's a really large square that is going a bit beneath my road. So if I click over
here, this will-- same ID-- this will scatter the
tree on that wall mesh. That mesh is going
underneath the road. That mean that we have
some change, that we have some tree going under it, and
that will collide with the road. To fix that, you can
simply select your eraser and just erase the tree data
just where you don't need them. Of course, you can use the
Scatter tool to scatter tree, but also smaller object like bushes. So if I come a bit closer to
that mesh, we're going to select, again, my Scatter tool. This time, I'm going
to add some bushes. I'm going to add them in my dropbox-- maybe also this one. And again, this doesn't work--
similar as the Paint tool-- it doesn't have a layer system. That means if you want to
add those to your project, you need to select them. You need to activate the
scatter tool and click somewhere in your scene to add them. Same thing here. Let's say I don't want some of
those asset over the small puddle that we have here. I will just select the
asset I want to erase. I'm going to enable the eraser. I'm going to set the diameter. And I'm just going to erase the
asset where I don't want them. [MUSIC PLAYING] You can use the Scatter tool
on a large area like that but also on smaller one. So let's say the top of our project
here is not a water material. Let's say it's actually some grass. So I'm going to the Library,
Materials, Ground, Nature, and I'm going to add that grassy
material onto that geometry. I will come back to the foliage here. I will come back to
my Populate, Scatter. And here, what I want
to add is some lawn. I'm going to drag and drop this. I'm going to select it. Click on Scatter. And I'm going to click on my Mesh As you can see here, it started to
add some grass onto that geometry. So you can work in
smaller area like that. Right now, it's
lacking, a bit, density. So what you can do is click a
couple of time to add more density. What you can also do-- let's
actually remove everything. What you can also do here is
just drag and drop the lawn a couple of time in your dropbox. So when you will just
add that to your project, it will have more
density, by default. [MUSIC PLAYING] Now let's come to the Ambience. And here, I'm going to
open the Weather Details. Here, we have a
vegetation growth option. The growth defined the
age of all the tree that you have added
inside your project. So here, I have some tree in
young, medium, and adult age. We have some bush. We have a bit of everything. So here, if I'm starting
to work with this slider, you will see all the vegetation
surrounding your project-- you will see it evolve over time. You can use this option to present
your project at delivery when the project will be
built, but then you can also showcase how it will look
like maybe 10 or 20 years later. There is a bit of wind
on the trees, but it just happening on the leaves
themselves, as we can see here. You can increase the wind in the
Environment, Weather, Details. Here, we have a wind speed. So you can increase that. But it will never make
your tree trunk move. To do that, I have small tips that
I'm going to show you in that video. So the first thing
I'm going to do here is add the Norway spruce
inside my project. I'm going to make this
one an adult version. Now what I'm going
to use is a rotator. So I will come back to Library, come
back to Tools, Animators, Rotator. I'm going to drag and drop
that rotator inside my scene. The first thing, here, I want
is that-- the X of my rotator should be at 90 degree, like that. I'm going to place
that rotator exactly in the middle of my tree trunk. And now I'm going to make that Norway
spruce a child of that rotator. It will look weird, but
after a couple of sittings, it will be a bit better. So I will select my
tree to make it a child. I can just move it underneath the
rotator itself in the scene graph. So I told you-- right
now it looks a bit weird. The first thing I want to do here
is set the animation to ping-pong, so it will move and come back
to its original position. Now I'm going to change
the animation speed-- something like 0.01 to start with. Now what I want to change is
the angle of that animation. 90 degree-- way too much. For that tree, let's start by
maybe something like 4 degrees. So right now, it's that straight, and
it's bending 4 degrees to the left. To not have the tree just bending
4 degrees to the left, what I'm going to do is give
him 2 degrees to the right, so it will go 2 degree to the
left, 2 degree to the right. So here, it's bending
a bit in all direction. Right now, it's maybe a bit too fast. I will select, back, my
tree rotator, and I'm going, just, to define
0.005, something like that. It's not because the
minimum value of a slider is here that you can't type the
value you want in the box itself. So here, I just typed
that lower value. I'm pretty happy with the result. Now what I can do is
duplicate that rotator. So I'm going to select
the rotator in the graph, And I'm going to duplicate it a
couple of time in my scene graph. So it's not perfect,
but just a quick tip on how you can add a bit of
animation to your project. And that's it for this
video on the vegetation. Thank you everyone for
watching it, and we will see you all for the next one. Bye, everyone.
