All language subtitles for 27-Creating our custom branch texture

Okay.

So now that I went over on how to actually create an atlas texture.

What I want to do now is I just want to go to text.com, and I'm going

to download these cherry tree leaves over here, which you can find

down here under your 3D scan Atlas.

Now, once again, I explained this in last chapter.

The reason I'm going to use these ones is because I'm going to

generate a branch that we can use on the tree.

However, because this winter, I was only able to find ivy leaves,

which

actually stay alive during winter to scan.

So the eggs, the techniques are all exactly the same.

The only thing is that I'm going to download this one's and I will, of

course just Supply these because I am allowed to supply them with text

that calm.

So I'm downloading those.

And then what you want to do is you want to go into speedtree and just

go ahead.

And if you go create a new tree, you actually want to go down here and

you want to use a cluster over here.

So it is a template that you can use.

So, this one's really nice as you can see it pretty much already.

Of shows what we are going to create.

So it shows like over here are branches.

Now by default.

It has displaying you do not want to move this.

If you want to go ahead and move out your camera.

You can always go down here and go to perspective and then you are

able to move it around so you can see how that this works.

So as you can see it pretty much the same as the IV, that's like this

trunk over here and then it basically just uses one single punch.

And then what it has it has like a multiple different branches on.

On top of this.

Now this one single punch.

I honestly I do not really like over here.

It's like broken off but it looks way too specific.

So what I'm going to do is I'm going to go ahead and I'm going to

delete this and let's see if I just grab this one on here now, so we

do definitely need to like, that's a buck.

Okay, let me just that's a buck.

The that should never happen.

That's a when I try to in do it.

So let me just try it again.

So over here, let's go into perspective.

So I want to just see if I can maybe like change these branches around

a little bit.

So I guess maybe the easiest ways actually if we hide the branch also.

So that we only have this one left over here.

Then if you go down here and click on perspective, and go back to your

X and Y plane.

Was it the xz-plane.

Oh,

Except I play, I don't know why my camera is so high.

But basically what we can do is we can basically move this down and

this will give us like a bit of like a better bunch and now we can

just basically go in here and we can mess around with things.

So we have like our default Branch over here.

Now, you do not want to really play around with like two threshold

renting.

Let's just leave those things for what they are.

What I do want to do is I probably want to go ahead and go to spine.

And over here.

I can control my length.

Which should be fine?

I think.

Let's see the thickness.

I probably want to go into my skin and I'm going to set my take this

like a little bit tin of over here, and I'm mostly then want to go

into spine, and just if we scroll down, I just want to basically play

around with my noise little bit.

So we get like some noise for what you can also do, like some early

noise, but it does not really matter.

So we basically just have like a basic punch.

Now if we just quickly, hide our Leaf match so that we can actually

see what we're doing over.

Here we have now.

These bunches like this.

I don't really like this.

So what I'm actually going to do is I'm going to go ahead and I'm

going to delete these and I'm just gonna use a normal part geometry

and normal branches, like this and then I should be able if I go to

generate.

Maybe let's set this to like here for.

So this was the original one proportional over here and then I can

play around with the numbers.

The reason we are seeing this is because if we go to

Show we want to turn off our normals.

So okay.

So we now we see this I can see that, I just need to go into my spine

and actually set my length a little bit larger over here.

And then over here, we can now go ahead and we can work on these

punches.

So what I'm going to do is I'm going to set in my generate, we get set

like the number.

You can hold it around a little bit.

But what I like to do is I like to often, it doesn't always work.

But let's have a look.

If we go to forces and grab a plane of force.

Okay, you are really far down.

Like this, it's sometimes allows us to basically flatten out our

branches.

So if we just go to our branches and go to forces, internal planer.

You see, it allows us to sort of like, flatten out of branches and it

this will require a little bit of custom work this type of workflow.

So if we now go back to X and Y plane, move this back into location C.

So they are now a little bit more flat.

You let me just move this down.

And now if I just go into my branches, I can go to generate and let's

set our first a little bit lower over here.

And I lost.

Yeah, I lost is fine.

I'm just gonna go into my spine and I'm going to set my length over

here.

Quite a bit smaller near the bottom.

And see.

So you have to cast you can maybe like move them around a little bit

just to give them like somebody Randomness.

But that's looking pretty good.

So we got some punch over here.

Once you have these binders, you can go ahead and go to node editor.

And if you have like one that you don't like you can always just go

ahead and delete it and just like that we are able to.

Also, for example,

Mess around with things.

Now for some reason, I'm not able, there we go.

I was not able to select them.

I know maybe I want to just do like some randomization.

Let's just go to generate.

Let's just see until I get something that I like.

So.

I like try to like, get like quite a bit of evenness.

A like, something like this looks actually quite good.

So, let's try again.

Let's go now into note and carefully select it and now you can kind

like move this around the way that you want it to.

Now this is nature.

So we don't want to go like to to uneven.

Let's go ahead and see your start angle.

I don't think you will be able to

Some Pablo tation.

No.

Oh, yeah.

Wait, here we go.

Now, we are able to do some proper rotation to little bit tricky.

To get it white, but it does work.

It's just because we are working from like this angle.

And what I'm going to do is I'm going to actually delete one of these

Move this one down over here and let's just get started with something

like this.

And let's just actually add our leaves so that we can see if this is

what we want.

So we now have a bunches.

Let's also do a quick save as because this one is quite buggy and we

are going to call this Branch underscore material.

So, if we are leaves, your leaves are pretty much the same.

You just want our geometry, and you can try to go to leaves and do

like a scattered leaves, but I'm just going to go ahead and I'm going

to go up here and you do like, a basic normal one.

So, we got some leaves over here.

Now, let's go into forces and turn on planar and maybe we can like set

the planer a little bit to make our lives a bit more interesting.

Next.

I want to have my leaves kind like sticking out words.

So we want to go public.

Only to our orientation.

And mess around a little bit more with like are aligned.

Also mess around a little bit more, like a folding over here.

And are facing your sister that until we got like a pretty decent.

Look, let's go into generate and let's set this to I just like

proportional.

It's one that I'm comfortable with.

So let's go for proportional steps.

Yeah, I'm honestly I'm fine with the generate settings.

I think at this point we can start by doing our actual textures

because we fully defamation.

We need to have our actual texture and everything.

So I think yeah this probably the correct one for now.

So if we go ahead and go up here, we can add a new material and call

this leaves.

And then I'm just going to import so make sure to set them to

two-sided.

and I'm just going to import our

Where are you?

Tree leaves over here.

So color, opacity and normal.

Oh, no, wait for this one.

We also want to actually have our roughness and our subsurface over

here, maybe set the subsurface to.

Oh, no, I think I actually want to have that in here.

There we go.

Okay, so we got this stuff.

That is fine.

Now what I'm going to do is I'm going to go to my cut out and I'm just

going to go for like four different leaves, or maybe like five you can

choose yourself but it feels a bit unfair.

If I use more than 4 because we only created for for our custom Atlas.

So you basically want to go in here.

And these leaves, you can go fill on Geometry because they are going

to be texture.

So you can really like.

Bush geometry so I can go in here and I can just start like a bunch of

desolation like this and then I get out them.

And we just want to do that to it.

Four of them.

Let's do this one.

And a bunch of tessellation.

So that we can just like nicely bend them around and stuff like that.

So that will be nice and if you want you can also show like the

backside of the leaves but those are always like a little bit of risky

because they might not always look good.

So I tend to just avoid that.

And finally, let's do pole like this one over here, seems pretty fine.

Okay, bunch of tessellation.

There we go.

Okay.

So those are our leaves.

We can now go ahead and we can just drag this onto our, actual Leaf

meshes.

And now you can see that we have some leave.

So you can imagine that.

If we break this down later on, we will be breaking down all of these

leaves.

So I'm just going to go into my skin.

One, two, three, four.

Set all of them to the leaves material.

And then set the mesh.

To the different meshes that we nicely, randomize these over here.

And now what we can do is we get first of all, just like play around a

little bit more.

We like to generate now.

I don't want to have too many.

You can very quickly out, like, too many of them and then, it will not

look as good next is.

Maybe we can try like a collision here like a high-quality collision

and then play out a little bit more.

So that we are at least avoiding having them, actively Collide.

And yes, next.

You can play around your job role a little bit.

So in general, you can just play around with a bunch of different

settings.

May be like with your first over here, to give it like a little bit of

spacing.

And, of course, let's not forget going into orientation, and then we

can do like, some folding over here.

So these ones I want to probably fold, probably fold upwards.

Give the like a little bit of curling here and there, give them like a

little bit of twisting.

Play around with your vertex amount and maybe like, set a noise a

little bit smaller here.

See so small noise, and then little bit of vertex amount and then

maybe also like mess around a little bit more with the Y scale.

So you can go in here.

You can definitely like make the top ones like a little bit smaller

and photographs.

You can like just in general play house with things.

To add some variation.

Same thing in generate with your size scalar.

You can go ahead and just make the ones at the top a little bit

smaller.

And then you can kind like just mess around with all of these

settings.

Over here so that we have like a bunch of different settings.

Okay.

So now that we have something like this.

Let's have a look.

I'm going to make them probably like a little bit bigger in general.

So that's looking quite nice.

And then, what I want to do is I sometimes just want to go back into

my branches and then in our note editors, we can go in here and we can

basically

Playa how it would for example over here like a hoe tations and

everything and just get something nice out of this.

So you have full control over this.

You can make like spent a lot of time making this absolutely perfect

if you want.

That is no problem.

So I'm going to go for something like this.

Also this kind of overlapping you have down here.

You want to often swine like avoided?

Like don't have it too strongly because then it's will look a little

bit strange because we are, of course, just form this direction is

what we will.

Take down.

So if we see the leaves like over here, then it will be a little bit

difficult to make them look nice because they do not really baked as

well.

So I'm going to go into my orientation.

I'm going to see my eyeline is pretty good, like my align, I'm fine

with it.

My facing, I'm not good.

So I think I will need to use forces.

These forces are not working as well.

Let's go into perspective.

And see.

So maybe if we go.

What shall we do magnets or Direction?

Maybe direction will work?

So, let's just set the direction.

Let's move it up.

Let's go back into X and Y plane and just see if this does like a

better result.

So if I go into my leaf Direction,

Yeah, yes, that does give better result.

And then at the very end once you think, like Okay, so let's call this

down, like

And I'm going to move this one over here.

A little bit higher.

Because cells, I feel like it will does fit.

You know, that's move it like this.

And I'm going to maybe like set this one down like a little bit.

Maybe move this one around a little bit.

and these lie that's a little bit annoying, like

Let's see.

I'm going to move this one in so sometimes you just need a guide like

play around with it.

I'm going to delete this these two leaves over here.

So, okay, so we got this.

Now with these what you can do is you can rotate them.

The only tricky thing about this is when you rotate them is that the

Collision might have other ideas.

So here, see, I am rotating them and sometimes it takes a second to

find the correct.

One you need for rotation by here C.

So that's, that's the anointing.

So with the Collision because it is colliding with it.

It basically just tries to avoid it.

So sometimes just deleting.

It is often better here.

These ones are fine.

Like this one.

I don't like so I can delete it and delete this one until I get like a

favorable position.

Same with these fancy.

He has a once I delete these I got like more favorable positions and

the only thing is that it's a little bit unreliable.

That's the only thing I have to say about it, so you can't like what?

You see, whatever works best for you.

Over here.

It seems like we have to sitting on top of each other, which I don't

really like.

Once again, like this one away, that's a scaling.

So it's probably

I cannot even see which one is the rotate.

Let's just delete it.

This one is how tight.

And this one?

Here we can move like down here.

This one.

I don't like.

So let's delete it.

This one.

I don't like.

So, let's delete it.

See that now looks better.

This one.

I don't like

This one, I don't like.

This one I don't like so yeah, basically it can be a little bit

fiddly, but it's a texture so you can like just want to spend your

time on it and I'm definitely not spending as much time as I shoot on

this, but that's because I'm just making this likewise quickly.

Okay, so we got those.

Let's delete this one and there you go.

So I after a while, you will get some really nice and favorable

positions and you just get in general like a quite a nice-looking

texture.

If you would look down on this,

Another something that we roughly have right now over here.

Yeah, I can even try to like move some stuff down here and there, so

perfect.

So once you are happy with it, the next thing that we need to do is we

just need to download a fairly quick bark texture for our actual

branch.

So let's go ahead and go to text.com and this time I'm going into 3D

scans and then if you go down to Wood bark, I'm going to probably grab

like this one.

Seems fine.

Like, that's more than good enough.

Do we all of them?

Yeah, of course, that's typical that all of them are not Square,

should be fine.

Like it should be able to register.

In speech.

We so we're just going to have the Albedo no map and roughness.

And now, if we go in here and out a, another material, call it back.

We can now go ahead and we so I didn't mean to do that.

Park go into settings.

Art.

Your textures.

And as simply drag the settings on the, like, your base over here like

this.

See, so now we also have a bug done and now you have a taxi done.

Okay.

So at this point, of course, you just want to go ahead and like play

around with whatever you want.

For example, I'm going to publish that my radius to be like a little

bit thinner.

Although that might mess up my leaves again.

If it does that.

Yeah here.

So that does little mess up my leaves and I'm not really in the mood

for that.

So I'm going to

Yeah, let me just make that I just like a little bit thinner and then

I will just pass the video and I will just like met play around with

the leaves again because else this won't take very long.

Okay, here we go.

So I got something pretty decent.

So at this point, I will save my scene and let's say that I'm now

happy with our bark.

Oh, and sorry, the reason I don't have my back material yet or again

is because I crashed.

Like seconds after I press pause.

So let me just very quickly re art.

Maybach material over here.

There we go.

Okay, perfect.

So, we now got these pieces over here.

That's all totally fine.

So, what we can do now is we can render this out to become an actual

texture.

So the way that you want to do that is you want to go down here and

you want to export material like this and what a export material will

do is it will keep overall.

It will basically register our viewport and then it will export a

material based upon this viewport.

You can also do this with, for example, if you want to have

Distant trees on a plane or something like that.

So buildbot billboard trees.

Sorry.

So what we can do is we can go ahead and do like a another texture

that will call Branch or actually custom.

Branch texture.

Over here.

So let's just use this one.

So 2048 by 2048.

Yeah, that's more than enough.

So I'm not too worried about that.

We don't want to have shadows on because then it will try to bake in

the shadows.

So often most of this stuff is totally fine.

Like, it's already by default.

We we are.

We want to have an opacity definition, that it will have like an offer

around all of our Lives.

We want to have a normal.

We want to have a gloss or do.

We will call it roughness.

We do not need an AO map.

We do not need subsurface, scattering that those ones.

I'm not going to have in this instance.

So this should be like quite easy.

So, Bessie, normal roughness, and this one should be like the base

color.

So,

We probably want to just call it base color.

And once you are done with that, you can press.

OK.

And then it will ask you.

Where do you want to save it?

So we are going to save the near it.

Will ask you the file format.

So I like TGA and then we can press save and let that run, which will

take a second.

Once it is done, it will automatically close the window.

And now she can see you will have these four pieces.

So if we go ahead and we're going to go into Photoshop to open them up

over here.

You can see that.

Now we have a normal map.

We have a base color map.

We have a roughness map and we have an opacity map.

You can clearly see on the opacity map.

The other Maps if you, for example, dragging your opacity,

Over here.

Then what you can do is you can, for example, quickly, go in here and

this way, you should be able to guide like she told him or what or

what I can do is of course I can just quickly just to Showcase you

select color range just like like the black pieces and then I can go

ahead and I can

here.

See.

So now you can see that everything is working.

Totally fine.

I just want to also do a very quick check with my base color.

So select color range.

Okay, and then I just want to go ahead and just add like a solid

color.

There we go.

Okay, and that's basically how we can generate punch textures.

And of course you can use your generate functions inside of speedtree

to generate multiple different variations.

Now, of course, at this point, what you want to do is you might want

to like play around a little bit more with your colors, like maybe

like the grayscale cause anything like that.

I will also play around with that but I always like to first of all

get started with actually having a tree so that I can properly preview

it.

So what we are going to do in the next few chapters is, we are going

to create our first three and we are going to actually use these punch

textures as the main textures on the tree along with of course, just

like a trunk texture for

Um taxes.com, but I hope that you can now understand how that I would

go over on how to quickly generate these type of Branch textures.

If I need to do them myself.

The next stop would be if you want to do much more advanced than

everything would be to actually do to your 3D modeling program.

Like for example, my or Max, and then bake it down just like, you

would bake down the decals that we create like the hood.

Decals.

You would basically just bake it down like that.

And then you would basically get the same result.

But of course, it would take.

Much longer to add some small, variations to your leaves and stuff

like that.

So let's go ahead and continue to the next chapter where we will work

on how to create a
