Hello,
everybody.
And welcome to a new section in this section.
We're going to be creating a tree in Blender 2.8 will be using an add on called the sapling
and on,
and we will start creating the tree with some different settings and getting it looking
just right,
and then we'll move on to the material,
the leaves,
and then we'll render it out.
The first thing that will do in this video,
though,
is enable that add on,
so go up to edit down to preferences and then in the search bar underneath the add ons.
You're just going to type in the word sapling,
and you should see a sampling.
Add on right there.
Go ahead and check that box,
and then you're good to go.
Next,
go ahead and delete this cube and then per shift a and underneath curb.
You should see a sapling tree generation out on right there.
If you click on this,
you'll see a tree pop into your scene,
then over on the left.
Here,
you'll notice that this loads up with a bunch of different settings and values that weaken
tweet to get our tree looking just right keep in mind,
though,
If you do anything like for example,
if you select a lamp and you try to go back to those settings,
they will disappear and he won't be able to change your treat.
So make sure before you do anything else in your scene is you get your tree settings
correct,
and then you move on.
So the first settings right here are the geometry settings and this 1st 1 is the bevel.
This controls if you want bevel in your scene.
So if I turn that off,
you can see that the entire tree just becomes lines and curves.
If I turn it back on,
it has a three d effect.
You can change the bevel resolution if you want to.
I'm actually going to go up to two right there,
and I'll leave this one at four.
You want to be careful with this value because if you add a lot of branches,
this will really slow down your computer.
Then under meet the shape,
you have a couple different presets for the different shapes that you want.
If you want a spherical shape,
you can change that.
They're the one that will be using,
though,
is the 10 flame.
So go ahead and select that one underneath that we have this value here.
And if you turn this down,
the branches will go closer to the bottom.
If you turn it up,
the branches will go higher.
And so on.
The value,
though at 1.5 is actually perfect.
So I'll leave it as it is.
The branch rings controls How many rings are on your branches?
And since we don't have a ton of branches in the scene,
we don't really see this doing too much the random seed.
This will just give a random variation,
and sometimes you can get lucky and find a cool preset.
We're gonna leave it at zero,
though,
because I want to do it myself.
The scale of this,
we're gonna be setting this to a value of six to bring that up just slightly.
Also underneath here you have a bunch of different presets as well,
and the one that will be playing with is the small able to go ahead and select that one,
and we can see those settings change.
I'm gonna set this back to six.
Okay,
Now that we're done with the geometry,
we can go ahead and move onto the next one,
which is the brands radius.
And this controls how thick the branches are and how big the trunk is.
If I turn up the ratio here,
you can see what it's doing.
It's really making the branches a lot bigger.
I'm gonna leave it at a 10.2 the ratio scale.
You can change this if you want to.
This just controls how it basically does the same thing as a ratio except in a smaller
version.
So you can see here it just changes of the size of the branches.
You can go ahead and turn on closed tip and this will just make sure all of the branches
here have a closed off tip and there's no holes in the branches.
So make sure you do that if you want to,
you can change the roof layer,
and this will just make your trunk right here.
Flare up.
I'm gonna leave it at a one,
though,
because I don't want that to happen next.
Underneath the branch splitting,
we can change some of these values and this is where we get into the angle of the branches
,
how tall they are on big and where they're positioned on the tree.
The first setting that we have is the levels in this controls.
If I turn that up to three,
you'll notice that the branches now have a lot more branches.
So it's taking the number of levels and then just adding to it.
So this trunk is the first level,
and then these branches here is the second level.
And then if we change it to three,
the branches will also have branches.
This value is for how maney splits you have in your tree.
Right now we have one.
I'm gonna said that 20 and we can see it closes that up the trunk height.
This controls where the branches are on your tree.
I'm gonna leave it as it is,
a hand that's a pretty good value.
And the split height controls where the split is on our tree,
and I'm just gonna leave it at its default settings.
Here is where you can set how many branches you want in your scene.
And for this tree,
I'm going to go with a value of 60 branches.
Actually,
let's go with 70.
I think that would be a little bit better,
so we'll set that to 70.
The split angle here just controls where the split is on your branches.
As you can see,
if I zoom in right here,
you'll notice if I turn this up,
those branches spread further apart.
If I bring him in closer,
they become closer.
I just like it as the default of 18.
I'll just leave it right there.
You can move the branches around your tree if you want to.
And you might notice there's four different values here,
and these are for the levels up here.
So you see,
if I change the third level,
nothing happens.
If we were going to set this to three,
then those branches would be affected.
So the only options that we have right now since there's only two levels are the first to
you can see this one doesn't do anything.
This one does.
And this one does as well.
Once we're done editing our tree,
I'm going to set the levels 23 But for announces,
we're changing the values.
I wanted to move a little smoother,
so I'm gonna leave it at two and will change that in just a little bit.
The next one that will go to is the branch growth.
And here is where you can set the size of the branches and the angle of them.
And for this you can see if I drag this up,
you can see the angle of the first branch and hear those will grow if I want to,
I'm gonna leave him at the default settings,
and the one value that I will change is the down angle right here.
I'll just drag that up slightly and the curvature.
I'm also going to drag this down so that the branches are angled up a little bit more.
I'm liking how our tree is looking so far.
I might change the length of this first value to be about a 0.9,
so it's just a little shorter,
and I think that looks pretty good.
Now that we've done that.
Let's go ahead and switch back over to the branch,
splitting and change the levels 23 And as you can see there,
we have a lot more branches in our scene and that is looking pretty good.
You can change it to four if you want to.
But keep in mind,
it will slow down your rendered time,
and it will slow down when you're adding the material.
Next,
go over to the leaves and here is where we can add in the leaves.
So what we'll do is we'll click on show leaves and then you can see all of our lives pop in
our scene.
And the next thing that I'm gonna do is come over here changing from a hexagon over to a
rectangle,
And there we go.
We can see what this is doing to our leaves.
Now you might be wondering why we're doing this,
and that is because we will be adding in a texture.
And it's a lot easier to UV unwrap a rectangle than it is a hexagon.
So we're gonna switch it over to rectangle and for the number of leaves,
we're gonna be setting this value to 64.
Once we do that,
we can see that there are a lot more leaves in our scene.
And you know what?
What I'll do actually is go back to the branch splitting and I am going to change it up to
a level of four.
And there we go.
We can see it looks a lot more dense,
and I actually like that a little bit better.
Okay,
so now we're done messing with the branch settings.
You can if you want to change the angle of the leaves.
But I'm just gonna leave them at the default settings.
I think that looks pretty good.
In the next video,
we will start you be unwrapping and adding the materials.
