Hello there and welcome back in this video just in our atmosphere a little bit more

Texture and add some more realistic elements into or foreground

So between this video and our last one I went ahead I imported our free

To run a little bit faster and something else that I did just like in week 6 I went ahead

And I'm rented out some proxies

For our sequence year I had my last one that I need to load in

And they were going to start looking at this in motion so it's definitely a good idea

To get some proxies gonna start doing some prerender

I did a pre render at this point

And have a proxy and here as well just so we can preview our atmosphere tweaks because this is something working

To see in Motion

Am I going to want to see it as fast as possible

So the atmospheres here these all have proxies

Loaded into them the particles do in solicitors going to enable us to preview this signal

Definitely faster

And we are getting before we're getting around

4.5 frames per second

And this is

10 times faster easily than what I was doing before

Another that is set up what's looking to Alan some atmosphere into are for grounds and

Talk about something that's very important in C&G shots

And that is adding real elements where ever you possibly can

And where we kind of been doing this throughout the class in week 5 we did our ground painting and added some real

Temperature in Tavira

In week 7 week had a real sky and background

And what we're going to want to do is add some foreground smoke that's running across my want to use real lol

Because the closer you get the camera

The harder it is to sell CD

And sell I'm again going to you something that unfortunately cannot

I'm going to go ahead and use this action vfx smoke closer or one right here

I wish I could give us out but I can from this atmospheric volume 1 collection and someone is going to use

SR reel texture because what I want to try to do

Is have a little bit more of a thicker Haze and then once we break through it reveal or

I don't want too much atmosphere in the later half of this clip

What's go ahead and get started with that I'm going to import or snow

Clip in a minute go into our atmosphere and smoke

And just bring in this one hot celebrity

Map 18 Souter srgb texture

And if we change this to input you just have some rowing for Drake here

And will definitely need to speed this up some to get it to sit but that's worry about tracking it in there

And we know had a track and then we're gonna go ahead and what's just steal

This setup walk happy and paste this

What we're going to do here is connect this to a master camera

And then use our position to points to roughly a lioness in front of Arcade

So we can make a card right here

With our atmosphere texture on it when it turn off or light

And there is our atmosphere up to go ahead Grabber positioner points we haven't deleted it accidentally

Can I hide this inputs not too important to have that visible

And let's go ahead and take a look at where everything is in 3D space

Alright to zooming out this card is not in the correct spot

Head scale this app Sam

Maybe we'll do something like 25 to start with

What's changes orientation to YZ so it's facing our camera

And what does cute the sky over

Something like this approximately now that were closer we can probably skip this down

And we want a rotated so it's in line with our camera we don't want any weird angles happening

All right so this is just a reference source type this in

Check out what's going on

So obviously this isn't quite sitting correctly Ellis just move this into place

This is working since we copy and pasted this scanline

What's a Commotion Bristol on let's go ahead driver can't control scooter down here and turn that guy

Off disable work faster

Because it's not gonna have to bigger than impact

And alright that skeletons up a little bit more

Over

Let's just play this quick and see what happens

It's a moving closer to it in The Mummy get really close

Something strange is going to happen

It's just going to pop off

And that's not going to look very good in our shop we don't want that to just randomly

Pop and that is because if we look at your camera here we're literally going through that card

At a certain point

And so what we could do

Is we could make a x here

And keyframe it

Full of her City when the cameras this Close keyframing again

And set it to zero

So that it smoothly goes through

If you start having

A lot of these cars that's in me a giant penis specially few camera changes it's just not a very procedural

And so what we want to do is make an intelligent multiply that is going to automatically find this one

Camera reaches a certain distance

I really have to do a little bit of math to give this to

You're familiar with Houdini at all you probably know what type of maths will I do

What we need to do is calculate the distance between or camera in a car

And use that distance to procedurally animate or x head and look into

Bleeding or length first

All I want to do is grab our card right here

Going to make a knob

Type of pencil tool and drag a floating-point slider down

And we can call this distance

Distance

Alright

We have

Created

And now we need to use an equation to calculate the distance

What's take a look at what that formula looks like I have the formula for magnitude here

That's what calculate the length between two vectors in 3D space this looks more complicated than it

I promise so what you need to do

Is take or cameras exposition

Subtract or cards exposition and then we Square

And then we follow the exact same process for the cameras y position in our cards y position

We swear that

There are cameras evolution in our cards are position

Square that and then we add the results of this together

And then we take √ that number and it's going to give us the actual distance between

Camera undercard

Let's go ahead and see how we can do this in nuke

And I'll keep this just to reference

After the side here

So what's going to Leeds distance

So what do you want to do first just grab your camera what's your dad's name that should be camera one

Speaking to you

Camera one

Dart

Select here

Been out is named

Translate

And this is called the camera one

And we want to grab the X component so dude x

And then what we can do

Is subtract or cards exposition for this we can just be

Pretty straightforward we can just say translate x

And Lucas smart enough to know that we are referring to the card when there's not a known name in front of it

I put this in practice

And then according to a formula the next time when you did you is square of this

And then looking at our new

Expression sheet you can square your value by using the expression power of 2

And so we can just say

How to

And now we have

This component

Overexpression

So now we need to add a duplicate of this except for a while

So what's this copy that's expressions going to get a little long

Add

Plus what's change this to our translate Wi-Fi card in our Translate y4k

Now I need to do the exact same thing

Where are the positions what does payslips again

Z

And z

Alright so now we have a good shark or a formula done

The final step is we need to take the square root

Of this result

Put this in parentheses

And when we reference our nuke expression guide again

You can take the √ a value by using

The Express

What's a square root

Privacy

Rothesay

And now the result is the actual distance between or card and door camera

How to take a look at this and make sure that it's working

As expected

If we start moving or card away

To do this

You can see the distance increase

As I move it closer we can see a decrease

Alright great this is our first step

So now that we need to do is remap the distance from value of 0 to 1

We want to specify

A Distance that member of this close to camera we want to multiply to be at 0

And when it's a certain distance away from camera or x can be at 1 or

Full strength

Well let's make some more nabs here

3 more

What's disconnected that accidentally

2

3

This one will name minimum

Merman

It just said be arranged for The Slider from 0 to 10

Make sure you name it for minimum if you name it men that's an actual expression in you can this will not work

And next up what's nameless maximum same deal don't just name it Max because

Otherwise you're going to have issues when it comes to an expression

And we can set this one from 0 to 50

You can go beyond these parameters it's just easily slide door knobs

And then this one we can name out

Out

And

The zero the one is perfect for this all

Great

So what say we want

Our minimum distance to be free

What's a card is within 3 m of a camera

This is going to be at 0

And when it's 10 metres away it's going to be at

What again look at our expressions what were after here

Is this smooth step here

You're Houdini user this the same thing as using outfit

And basically you give it 3 values

You give it you are minimum

You are maximum

And then your current value

And if it's below your minimum it's going to return zero if it's above your maximum going to return one

It's in between it will smoothly and terribly where it is between these two values

What's go ahead take a look at that here

And so what we want

Is smooth

And we need some fantasies so we want to grab or minimum

Our maximum

And these names are what we named these knobs here and then we need to grab our distance

Alright so now if we start moving this we can see when it's beyond 10 or out stays at 1

And when we shoot it in

And it's closer than three it's at 0

Chanel the beauty of this is we can link this out

2 are multiplied

What hobby the likes here

And paste it into your x

And now let's go ahead and take a look at what this is going to do for us

Whatever x selector

And Ezra moving closer it's smoothly fighting off

Our atmosphere

According to these men and Max values

We no longer going to get that chunky dispersion as you're moving too close to your image

And this is Perth

This is so much easier than setting up a x and animating it manually

Because now that we can do

Is when we copy and paste this setup all either turn on or expression arrows

Is there going to be nice to each other and it will just automatically fade based on the distance from our camera

We can even see this as a tool set

Go ahead and say

Card auto fade

And if we make that

There we go

We'll have to make sure that our camera is named camera one when we use this tool set or we could just change the name

The camera the three times that it's in here

But now we have the set and ready to go whenever we need

Let's go ahead and start seeing how this works

Over hour footage

So I'm going to hit all tuite turn our expressions off

Let's measure over our atmosphere right here

Skip this

Right now or alpha is completely Saladin this and that's not very good

Let's just make a Kia

You don't have to change anything

And now we have a little smoke alpha there

And it's been merged over so I had a look at I can't receive you here

And I really want to increase the intensity of this

What's go ahead and clean it up

4

And then can I up some as well

Maybe something like that and let's take a look at what we have here

Alright so I think this is a good start obviously we have some colour issues here that we're going to need to clean

A little bit

And we also have some speed issues let's tackle the speed as you first

All we needed you here is add a real time

What's set the speed at 2.5 so it's moving faster

Play the San Siro we have

Talking better I feel like this is blowing it all too much that's what they showed is doing something turn that off

So the single frame all our scanline render do the Blur on here because I want to keep as much detail

As possible

What's go ahead and keep preview in this and see how you feel about the speed

Alright then 2.5 maybe a little bit too fast was take a look at what he looks like instead

Something like that is working a little bit better

Right now I do think this is a little too intense

I'm actually going to make a colour correct

After a scan online

I want us to be kind of our individual colour correct to you control the intensity and this is going to be our actual

Colour colour correct

Go ahead and open up or colour wheel here

And we can just

I want some colour into this

Start trying to line up without seeing something like that doesn't really take much to get this to look good

Is pretty intense right now slower this a bit

Then we can get it down a little bit as well

We can play this

And now we just had a nice layer

4 grand atmosphere it's automatically fading away which is very helpful

And it just had some nice detail that's hard to get in Sims when you're this close

You always want to make sure you're adding as many real elements into your shorts as you can because they're really just gonna

Every little one will go a long way

What's go ahead and

Keep working on this

You can add some more in here lyrics copy and paste or procedural setup

Legacy Noel here we don't need this one anymore

Take a look

In this one I want to move back

What shut up

The Swan temporarily

And the sky we can make very large

And

Connect this

Here

Connect to here actually so we have some more control I'm just going to copy and paste

The settings at the start

And I'm just going to add a time offset

So that we're not getting the exact same section all the time are said it may be negative

400 frames are so

Just so that it's a little different what's your this looks like

And a nice big puff right there

I think this is looking pretty good

To make sure that it's covering the frame the entire time

We made this too big and go ahead and check that out we want us to be a small as possible

Let's go ahead and check it out or make sure that our x is still working correctly as the start

The move closer and closer

We can see your nice smooth

Fade out right there maybe we want it to stay

Eating out a little bit earlier cos this is pretty intense the entire time that's the beauty of the system

If you can change the name on

5

The maximum to 15

20 even

Just have it filled out a little sooner because we want to be mostly revealing are spaceship at this point

We can work here

Turn both of these on and give us a quick preview

I think what I want is this left friend to be filled other more specific at our time offset

We need a due to get that a happened

Something like this even though it's pretty easy

What's your hair take a look at these guys make sure you're not going too far back

With the if you can scoot this one a Little Closer

This one as well

I'll take a look at this without contrast

Yeah I like at lower half of frame is being filled out now

Go ahead and play this

Nice and I like that initial burst of dust that we have going on there

Go ahead take a look

Position

The points

So it's like this may be a little while not actually causing some funkiness

And make sure you don't get this Horse online that's just go ahead and make a crap

At the bottom

And we can just soften sx8200 pixels now just feathered up because we don't want anything

You'll be clipping into a ground too much

Take a look at this again will a previous so fast because of our proxy said

Which is very helpful

And now we're not quite filling that corner over there is much better also not digging into it which I think is a good thing

But see maybe if we can

Adjust this card with the time offset to try feel that left a side of frame a little bit

More

So I can do -100

Very girl

What is the minimum amount

Something like that even

Alright nice we have some good text we're going on in here let's go ahead and just add one more

Is kind of eight even further layer of this copy and paste this set up here

Type it in

Emeryville work so fast because of this nice card setup

Surskit the sky back

And the scale up more

I want to make sure that were not cleared been into the bottom yet again

Something like that potentially

Just another layer of atmosphere this one's pretty Summer by the time we get at this point which is what were

I do need to remember the time offset this though we don't want

Seeded textures going across

So do you

Is there another

For one day we can do like 106

What is Inbetweeners 2

Is 580

250

It's something

This could work because again I want us to be fairly obscure Don the start frame

You that maybe asked you this down a little bit

What is r

Out alright cool

Go ahead and look at the sky on its own actually I will make sure this is doing well I think it's doing

And let's go ahead downhill preview this without ringing and everything

I think I'm going to turn or expo glow off cos it is a little bit of a slow effect

And let's just preview what we have

Call and now we just have a nice little layer of realism

In front of our shuttle maybe I'd like a little bit more dust in this beginning we can add 1

4 potentially as just do that will copy and paste the sky

So just don't want us to be too dark

What scooters closer to camera

Something

That

What is that doing for us and we can school it down a little

Girl that starts for the area then I think we're missing

What's check this out again

Sweet I think this is looking awesome it's just another nice layer of real dust in front of it once we had

Emotion wear with a scan line

A little bit more natural to

So let's go ahead and just

Make a backdrop here

Did you copy and paste this guy

Little t h

Foreground atmosphere

The last thing I'd like to do is to take a look at our

Sun texture right here

I'd like to try just a little bit more break-up and detail into this because I think her foreground is looking pretty good now but

We can get some more texture

Back here

And so how are going to do that

Is with a noise

I actually not going to use the standard noise mode

Instead where can I use the advanced noise no

What is the difference of the bet on these two

As your notice

There is absolutely no difference

What noise advanced does that regular noise doesn't because by default they are the same age

Noise just has a couple more controls

Or in the meeting the evolution of your noise that's a little bit more difficult with your standard now

So what's go ahead and take a look at those

And so there's this speed of Z slider so we change the subpoint one it's going to evolve

White one

Perfume

This makes it really easy that anime with the noise you of course could dive into

And make this happen but you have to do expressions and it's just not as easy to adjust

As the snob

And so I really loved using it has all over same control

An in the exact same vein

In a transform tab

You can just automatically have this move in a given Direction over time

And that's what we're after here

Our storm is moving to the left so let's do that

You may be -10 to start with

WhatsApp or gain

We will use this is a little bit of a multiplier

For our sun atmosphere here

Just going to add some more detail like we have more dust than really exist in our SIM

So they shouldn't be too difficult to setup I don't think

Let's see how this is the working

What start off with this and see if we need to change anything

So let's make a master can sit up

Red and white the sky in

We can make a card

Position of points

Populus canadensis has expression in it

What's make a card right around where our spaceship is as well I want us to try

So make one

Pretty significantly

What do you

YZ

Rotate this the camera this is nothing new again and we'll go just a little bit behind it you can skillet

More

Animal scooter darts that's not in a setting up the ground too much

Say something like this

White noise in right here

And take a look

Sweet

We probably want to throw a crap on here as well just say we have a soft bottom

Don't want any hard maths in our image we can help it

Looks like you can see that over there so it's just scoop this is E over

Derry girls on make sure that's the whole time

Alright

Go ahead take a look over here with the atmosphere

Swingless over to the other side

Make a colour correct this is just like when we were making our noise

In week 7 and 5

Except this time it's just animated to give it a little more punch in this world in Storm

And we can go ahead a fact or GBH son

Take a look at that right here

And let's just put this up

Maybe 1.5

How to tell if this is working like we want to hear maybe let's look at it in contact with the other

Is just selling a little bit of texture back there

We can probably speed this up Sam

Looking at it

It would to you negative

15 that's also up the evolution

And I was just getting some more text you back there

It's all about these saddle increments of texture

Alright

Something I want to make sure I'm not doing too much as I don't really want to be affecting our s***

With this because we definitely are a little bit here for looking at rgba son

I want us to be mainly a background effect

And so that's not going to be too difficult to fix

Let's go into our ship here

And make a little postage stay at set up for ourselves

Ship

Because I'm going to use the position Matt to make yourselves a nice little mask make the soft fun break

Orange will do

Make-up postage stamp

Next

In ship

Folded and hyder in alright

The all the way down here

Is take a look like crab or a friend the

HEMA

Wardrobe or position past here

Let's grab our worship

And let's just start scalenus up I just want or foreground

No change the fall off a bit

Dance cute more towards camera what direction is towards camera

So hard to see here

I can just hold

Click and drag

Something like that I think

Skill Applemore change this to quadratic so it's a little bit smoother

Something like this

We have this engine issue again we not had a solid that at this point or making Edge extend

We will affect RP

And we're not going to use the detail about

We will not be free multiplying here

And that goes away

Sweet

And now we can just use this to stencil out or no eyes so it's only affecting our background

Bus to stencil

And now we have this nice little almost as soon as the depth mat

Warship

And now we just have this nice little texture in here

What's go ahead preview this

See what we have going on

Alright and it's all back there but it does add a nice amount of texture that we just didn't really have before it feels like

Another layer of dust

And you can do this a couple times I'm just going to stick with it once but I really like the way that our atmosphere is looking now

To bring it to life in an in that for grandfather really help selling real elements is always a good thing

And so I'm in the coldest good on the atmosphere I'm going to set up some right notes so we can write out

Is heavier effects special to turn motion blur on this is going to start getting

Really slow

And in our next video when I take a look at adjusting or fire and get that looking a little bit nicer

Thank you very much for listening
