All language subtitles for 06-Setting up our folage materials and test scene

Okay.

So what we will be doing in this chapter is we will go ahead and

create a smaller seen that we can use to just quickly preview our

foliage and then import our textures and set up our materials.

So I'm just going to go ahead and I'm going to go file and just do

like in but a new level over here and I'm gonna go polevich like a

simple.

Default level.

That should be fine.

Here we go.

Okay.

So this is going to be very simple.

First of all, let's go ahead and go to file and just do a quick save,

current level s

And let's save it into our editor.

Where are you?

Oh God.

So many photos.

I'm looking for easy.

There we go, easy for each toil saves preview on the score map.

That's this.

What I will call it.

Here we go.

Okay, perfect.

So what I'm going to do is this scene over here.

It is still the old seen from Unreal Engine 4, and I do not like that.

So I'm going to pretty much get rid of my, let's see my

Oh, no, you know what's yeah.

Players start.

I can get rid of I guess I can really use the rest.

I guess I can just reuse whatever we have here.

So let's also get rid of the base Cube over here and I'm going to go

to create shapes, create a brand new Cube now in your location.

If you press the little arrow button over here, it will reset 2000.

And then I'm going to just make it like 0.1.

So I'm going to make it quite thin like this.

And then maybe like 30 by 30 over here that we just have like a simple

plain.

Next.

What I'm going to do is I'm going to go create shapes and create

another Cube over here for this coupon.

Just going to go ahead and I'm going to scale it up and out a little

bit.

Like this and this will be for previewing our actual IV over here.

Now, if we go to our source light, we just want to go ahead and set it

to movable so that it is real-time lighting.

I'm going to go ahead and go into my light color and maybe like, give

it like a little bit of like an orange color like this next, maybe,

rotate it a bit.

Or not.

I don't know.

Let's do something like this.

Let's rotate it a little bit like this over here, Skylight.

You also want to set your Skylight immovable.

You can do a real-time capture, but then it will require a sky

atmosphere.

So I'm going to go ahead and I'm just going to leave it as default

right now.

So that's totally fine to just leave it.

It's just a quick preview, what we're making here.

And I think that's pretty much it.

So we have our reflection capture which is covering the inside Tire

seen over here.

So yeah, this should be enough for us to just quickly preview and we

will just go ahead and like, improve the scene as we go along.

So what we can do is we can go ahead and just import our or Dragon.

Riv generic.

I'm going to rotate it over here.

See this the front, it's still difficult to see, which is the front

and which is the back.

This is the front over here.

There we go.

And so yeah, this one would be like on, like Corners.

So, it would probably be somewhere over here.

If you want, you can turn off snap rotation and like do a little bit

better rotation over here like this.

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

click my materials.

Now for this.

I'm going to right click and create a new folder that we will call.

Materials and in here I'm going to make a right click material that I

will call foliage underscore Master like this.

So the foliage Master will basically be covering all of our materials.

Now there will also be one that is just like not a material that is

solid on the scrum master and the solid Master will be for our bar for

our bark in everything.

So let's get started with the foliage Master over here.

Let's click and drag this up here and then we can get started.

Now.

The first thing I want to do is I want to go to my taxes, right?

Click new folder IV, underscore underwater.

Generic IV underscore leaves because we are importing a custom

texture.

So if we go from speedtree, here, we are going to import this custom

texture.

I don't need subsurface o:.

Almost the only one that's just being exported.

But that's fine.

So we can go ahead and we can import this.

And then, we can also go ahead and do IV on the score.

Bark like this.

And then if we just grab these two over here and then the rest we can

do inside of Unreal Engine.

One thing to keep in mind is that we have our no map in opengl.

Remember how he did that in substance designer.

However, Unreal Engine reads as DirectX, so you just want to open it

up and press the flip green Channel and I believe that we do we need

to do the same.

No, we do not need to do the same because these come from Magus

cancer.

These are already coax.

Perfect.

Okay.

I'm going to grab my collar and my, normal of my ivy leaves.

And I'm going to import it in here or just drag it in here.

Now, what we're going to do first go to your foliage master.

Let me just move this over here.

Let's go to our blend mode and we are going to set this translucent

and I'll shading model two-sided foliage and also click on two-sided

over here, which will give us a base color and a opacity.

But we want to have more stuff because we also want to have control

over our normal roughness, and we do have a subsurface cover, the way

that you can do that is by scrolling down, and in your translucency

tab, in the light.

Seeing modes set this to be surface forward shading.

Yes.

That's the one surface forward shading over here.

Now.

There are few things that I want to do.

First of all, I want to, right?

Click.

And I want to add something called a constant tree vector, and what is

it is basically a plain color.

So what I want to do is I want to also art if you right-click a

multiply and I basically want to multiply my base color texture.

And then displaying color if you right click and convert it to a

parameter.

You can call this color overlay.

Make us whites.

Was it?

Ok and apply it here?

So what are we doing?

We are basically multiplying our base color texture with this color.

And because it is a multiplied whenever the color is not white, it

will show up.

So if I make this ahead, my leaves will become a threat.

The reason I converted to parameter is because we are going to create

something called a material instance, which I'm sure many people

really know because I do require a basic understanding of unreal if

you want to follow this tutorial, but basically the material instance

are

Us to change this color inside of the engine.

So we need to do the same over here for our base color right.

Click convert to parameter and just call it base on the scope color.

And a normal, right?

Click convert to parameter, normal underscore map.

Like that.

Next what we want to do is.

So we have a color overlay so we can simply plug this into a base

color over here.

Alpha x c contains our mask.

So we want to plug this one in to our opacity, over here, and then are

normal.

We can just simply plug this into our normal.

But if you want, what you can do is you can hold s and click once and

that will create the scalar parameter and call it.

Normal on the score strength, or you can right click and type in

scalar parameter like that and set the normal strength.

Yes, 20.

And if you then add a note that Scott, a flattened normal like this.

The cool thing is that you can plug in your normal and your normal

strength over here.

And I believe, actually, I need to go from minus 1 for our base normal

strength.

And then, if you plug this into your normal over here, what will

happen is, it allows us to control these?

Strength of a normal.

Now.

I just realized something is going wrong.

And this is a bug that happens with Speed 3 that I believe, there is

no way to solve it inside a Speed 3.

Because even if we try to export our material,

Yeah.

Yeah, I we can Twilight.

Let's say the exporter game.

Ivy.

Now see here, so I do not think that there is an actual fix for this.

Basically.

What is happening is if we open up Photoshop, which I still have open

perfect.

Oh, only it's on my wang screen.

Oh God, come on.

Just let me go.

Thank you.

Okay, so if I open up over here, my leaves and go to my offer.

This is the problem for some reason.

Speedtree always decides to make the authors like specter.

Like in terms of specs over here, which is not what I want.

Super easy fix simply.

Go to image, adjustments, and levels as simply push your white slider

beyond the little curve that we have over here.

So then you are it so that you can be rest assured, that this is white

and then just press Ctrl s to save it.

At which point if you go into in real here, we can right-click edges

to re-import our color or base color C and that fixes that.

Okay.

So we got that stuff, done.

Another one that I want to do is I want to add my subsurface color and

the way that we do that is we are take on stand tree, Vector right,

click convert to parameter and call this.

Sup on the school color and make it like a light yellowish color.

I would say a light.

Yeah, lights yellow, greenish color, something like this as like a

base.

And then, what you want to do is you want to multiply this.

Using a scalar parameter.

So s.

Click and this will be

Sup surface on a score strength.

And we want to set this to 1.

Like this and simply plug this into our subsurface color over here,

which will basically allow us to control both the color and the

strength of our subsurface.

That's pretty much it.

What we need for now, or wait, maybe like a maybe like a scalar

parameter so s click for now, that's will call craftiness and let's

set this to zero point, seven by default, which basically one means

that it

It is looking very dull.

Zero means that it looks very shiny.

So I'm gonna go like a little bit in between that plug this into your

half - just to give us a little bit of control over that and how we

can save our scene, we get actually check this out.

So let's go in here into materials.

We have a foliage master and just right click and create a material

instance and call it ivy on the score generic underscore 0 1 and this.

Basically, what I was talking about, if I open it up, you can see

that.

Now, all those settings that we

Turned into a parameter.

We now have control over those so we can now go ahead and go into Ivy.

If I just press the little search button to find it.

I can then go back into my videos and click on my IV.

Generic and simply add it using this arrow button in here.

And now we should have a two-sided.

Generic IV.

I think I should have gone for must instead of translucent then die.

Yeah I should have gone for

Just so let's go ahead and go in here and let's go from translucent to

masked over here.

And then all we need to do is just plug your offer into your opacity

mask.

There we go.

That should give us a better result.

Mmm, still.

I feel like I'm losing.

I'm missing a lot of leaves.

Obviously, just me, let's have a look.

Yeah, I'm definitely missing like a lot of leaves over here.

Interesting, because I don't seem to be missing them here.

So,

I'm quite curious.

Because they should be decided.

So I'm just trying to kind of like, have a look around.

Make sure if I'm missing some, I can also go ahead and I can not in

here, but I can like double check in here.

So if we go to lids and show wireframe here, look at that.

See so you can see that it is missing a lot of stuff.

Now, most likely because I do like to always keep in our debugging to

see what is going wrong.

The first thought that I have is that if I would, for example, art

like a plane bark material, if it comes back, I know that.

It is the amount here.

If I just quickly, click on my plane back material and just quickly in

the material just set it to two-sided.

I just need to do this because I also cannot see what I'm doing.

So two-sided.

Yes, C.

So here you can see that.

Everything is working toward defined even as like some a 0 in here,

which means that most likely something is going wrong in our UVs.

In our lives and you can check your Visa sexy over here.

You can set this to 0 and here you can see.

So, these are UV.

So here it looks like that they are flipped, see?

It looks like that somehow they manage to be flipped around in here.

Which is quite interesting, so could it be that maybe those settings

that I did?

So if I go to export to game over here, I set the setting over here.

I turned I turned this off because I thought it was it was for our

geometry, but it might actually be for our UV.

So let's go ahead and just re-export this just to double-check.

And let's see if that fixes anything.

So if we go in here, so if I go in my UV editor and open this up, yes,

that is definitely one.

And now I did export this, but it looks like that it still does not

import it.

So, let me just quickly file and do a quick import.

And importantly, import over here are IV.

Generic

That is curious.

That is interesting.

I'm going to in do this.

Oh God, I got to know.

So I'm just going to reopen my scene so that I do not extend loose.

What?

I just accidentally deleted over here.

So, if this is not working, what we can do is, we are able to add a

texture to this now, and then flip this around to do this.

I would probably need to go ahead and I would need to go to face and

if I just

the Wasatch control-click

because I want to select and I forgot how to actually do this.

I want to go ahead and I want to select by material.

So you want to go ahead and convert selection.

Let me just quickly check because I have not used this feature.

Has so long.

I completely forgot.

Actually, I found an easier way to do this.

If we simply select all of this and then hold control these select.

So I hold shift.

Control shift.

Come on.

Just let me shift.

There we go.

Okay, so it didn't allow me to do it to select these pieces.

So we need to be

flipping it.

First vertically.

Yes, so it needs to be flipped vertically.

So if we go ahead, and if we go over here, let's see.

Flipping flipping so similar twice.

No.

Flip on the V axis.

Is that it?

Yes, that looks now, correct.

So let's try that out.

So we are flipping it on the V axis over here, and I've never accept

this poem.

So that's quite curious.

But then again, I've never actually.

This is the first time you're working in speed 39 for me.

So and I'm right away, just making like quite complicated.

Well, not complicated stuff, but still quite intense stuff.

So maybe that is like the problem.

So now we can go.

And even if we just re-import this, there we go.

See.

So it is now flipped around and now if I just go ahead and just turn

off my a-v, grab my IV genetic and hopefully if I apply it, there we

go.

That is looking a lot more logical.

So that save our scene.

Yeah, that is looking more logical at definitely.

So now I just need to check.

So this is the front.

Okay, that's fine.

So you would kind like places next to the plants or whatever over

here.

And now there's a few things that we do want to balance out.

So if we just double click on our material, so yes, we do have this a

0 that is going on inside of here.

This is something that I tend to fix with lighting, it is

All settings in here.

But this is an Unreal Engine five things.

So right now, because of this, using these key, the farm not far,

distant chatter.

Oh God, what is this called?

So I have a brain freeze distant Fields ambient.

Occlusion.

It is trying to applied it in here because we have a two-sided now,

there should be ways that you can reduce the effect in here inside.

Maybe like your lighting over y, distant Fields, self shadowing.

Or maybe not maybe that is not possible.

But anyway, I tend to fix this using here, C.

So affect distance field, Shadows.

But I didn't affect this using a balance of a subsurface color along

with are just like General lighting inside of a scene.

So, we have this over here.

I want to go ahead and just quickly check if I set it to know.

Okay, so I want to go with the normal of minus 1.

I'm just making sure my normal is in the correct direction.

Yes, roughness.

I want to go 0.9.

Is there a half inch being flipped?

No, nothing is not being flipped.

I don't think.

Yeah, the colors I don't really like the colors.

Let's do a half minus zero point.

Let's do c.

Okay.

Let's do see how point eight or subsurface colorful set is the to 10.

Okay, so that one is way too strong.

So that's 20 point.

One, this will look very better in our scene.

I will do like a little bit of balancing out later on.

I'm going to make my subsurface called a little bit more orange over

here, and I'm going to make my color overlay, maybe like a little bit

darker and maybe go a little bit towards the green values.

But this is all bouncing out that we would need to probably do

properly in our scene.

So, if we have this, let's set up my half and sexy 20.6 over here for

now.

And then I can see that I have this classic Buck where you can no

longer move.

So it's setting.

inside of

Unreal, which allows you for some reason.

Basically, it's it's Blocks Your movement and you kind of need to

switch back and forth between a software, a different software in

order to get it.

But okay, so this one is working.

Okay.

For now, we still need to have a, we still need to do a lot of stuff.

But at least what I want to do now is I want to go ahead and work on

my solid Master which going to be super easy.

It's literally just ask going into the IV bark.

Selecting these two pieces throwing them in the air.

Beige color.

Puffiness.

Let's go ahead and let's go to your foliage master and just quickly

copy over these three notes over here.

Baste them in here.

You can just plug this in here.

So this for a base color, and this one is for our roughness, and this

one actually was supposed to be normal.

Sorry about that and then just right-click and convert to parameter

this base color.

Do the same with your normal, right?

Click on vertebra?

Amateur, normal map, just like that.

So super simple for now all we needs we are we will be improving this

as we go along and simply right?

Click create some gel inserts and just call this IV underscore Bach

because we will be creating like more different types of foliage

materials with this.

So, we have Ivy bark and now if we go in here, just apply it.

In your solid mile, so just make sure that you turn on two-sided and

press save.

Give that a second and then it should give us a pretty good.

Effect, but we'll see.

Saving takes surprisingly long.

There we go.

Okay, cool.

So here we go, here we can see our foliage over here.

If you feel like it is too dark.

You can always go into your IV bark over here on this color and set

this brightness to like 1.5, for example, or maybe even two to like

make it a little bit brighter and then if you want to balance it out a

little bit, you can then go into your IV bark material.

Which I will do work down here.

And then if you click on Your Collar, you can then just like mess

around with the color to give you a little bit more control.

But anyway, so that is looking pretty decent.

So, having this also from a distance.

Yeah, I think the bark is not a gene.

That's looking good.

It looks very much like it is, just the simple geometry, even though

it is not, so that is looking pretty decent as like a begin.

If you go want to go ahead and just like preview this quickly, we can

always go into our and that's the last thing about doing this chapter.

We can always go into our terminal.

Korea collapsed tunnel saves this one, is the one I need to believe

that we go and if we don't go ahead and for example here, so this will

be like generic.

So let's say that we have the over here.

I can go assets.

I can drag it in here and then I can also meet li like test out some

stuff.

One thing I want to do.

It is foliage in this specific scene is I want to turn off.

If you go down here in your settings.

You want to go down to

Handling and then turn off receives decals because I have like a bunch

of details in here and I don't want to actually have those on.

So having that done, you can now see that?

I could like place my foliage in here, I can scale up and down.

However, I want and I'm from a distance.

It does look a bit like foliage.

Now.

I definitely need to go out and I'll need to like do some more

bouncing.

So I'm going to like Place one over here.

One over here.

And what I want to do is basically in our next chapter is we are just

going to nicely balanced this stuff out.

So if you go ahead and click now, so it's because of my go twice.

If you go ahead and click on this box over here, you can rotate based

upon your object Direction.

Don't do too much, because, of course, to look strange, if you're all,

if you want, I ivy plant is rotate like that.

But what I want to do is I want to go ahead and

If you go to like a distance, I want to basically make this look good

because right now it is looking quite awful.

So that's what we will be doing.

In our next chapter is we will go ahead and we will balance this out

specifically like our office and everything.

We just need to like play, how to things.

So yeah, let's go ahead and continue with that.
