hey everyone it's great to have you back

the topic of today's video is going to concern

how to art direct your volumetric cloud

now anyone who's ever used volumetric clouds

at the under of 4.26 knows that

you know they're kind of limited in which you can do

there's not much documentation on how to set these up

to have a bit more control

but fortunately Chris Murphy over at Twitter

kind of put me on the right

track and made me aware that having

full control over the placement of durclouds

is even a thing so

I gotta get credit where credit is due

thank you so much Chris

you're the best

now with that being said

I'm going to take this to the next level and show you

how you can set up your scene correctly and have full

control over the art direction of your clouds

no not you the

creepy

clown behind you

and so why wait let's go

love love love love

okay so before we get started

there's two things we need to do here

so first of which is going to the setting type of top

click on this

and make sure to click on the plug in window

open up the plug ins and here we'll search for

Volumetrics make sure the volumetric plugin is enabled

if it's not there

you're not going to be able to play the volumetric

clouds so make sure that's enabled

rethrow the engine and we're ready to go

and before we get started

there's still one last thing we need to do

and that is paying attention to right here

so notice in my content browser here I've got

just my content folder

there is still one thing we need to enable

to access all the setting that we need

for this tutorial

and you'll notice the bottom right here

we've got view options

we're going to click on this and make sure that Show

Engine content

is selected and now notice on the left hand side here

we've got a whole

crapload of other folders

you're going to see why we need to enable this

real soon so hang tight

now we're ready to get started

and have a little bit of fun with our clouds

so the first thing we want to do is we want to create

a volumetric cloud system

so you click on visual effects here

volumetric clouds

going to click on this bring them in

and you'll notice right away like okay cool

we've got clouds but

by default they don't look very good right

yes in the detailed panel here

there's a few settings to begin tweak

but you know ultimately you don't have that much

control over the art direction of your clouds

now with that being said

we can

edit the material that is in the volumetric cloud

right here

and we can play around with the settings like this but

we don't really have control over

you know the position of the cloud

and that is what this tutorial is about

so I'm going to close this and

let's get to the juicy parts of this tutorial

so with our new engine content folders here

let's scroll all the way down to V

where it says Volumetrics Content

we're going to click on this folder

and we're going to click on the tool folder right here

cloud Compositing

blueprints and we have two blueprints right here

one called BP Cloud Mask Object

and the other one called BP Cloud Mask Generator

I'm gonna collect both of these and I'm gonna drag

these into the scene

so you'll see one of the actors

the cloud mask object is freakishly huge

it is massive

I'm gonna move this guy away

way way way over here

now you'll notice nothing really happened

what's happening right what do we want to do here

so

the next step involves

changing the material that's on the volumetric clouds

actor

so I'm going to select a volumetric cloud actor here

and in the volumetric content we're going to go to

content

sky materials

and you'll see

we have a whole bunch of new materials here

a whole lot

so for the sake of this tutorial I'm going to use

volumetric cloud 0 3 profiles

Billowy

drag this into

the material slot of our volumetric cloud actor and now

coal wheat we lost our clouds what's next

so what we're gonna do here we're gonna select this

BP Cloud mask object here and we're gonna scale it up

by a lot

okay so I'm gonna scale this bad boy up to like

24 25 or something

and move him way further away but now

notice how the position of our BP

Cloud Mask object

it has

gives us full control over the position of the clouds

so let me get a bird's eye view here

so you can get a better idea of what's happening

okay so now

now we're way high up in the sky

we can see that hey our cloud is

moving around if I duplicate this

I can have as many clouds as I want

now obviously the shape of this cloud is garbage

it looks like a hot steaming pile of crap

how do we fix this

so we're going to select the first one here

that I created

in the details panel

I'm going to go ahead and

you'll notice that they're noise settings

I'm going to also click the show debug button

right here and you'll notice we've got a

kind of a red

marker showing up around where our actor is right

so this debug

plane here is going to show it what the shape of our

cloud is going to be like

okay so in the noise settings

I'm going to increase the noise intensity by 1

and now you'll notice hey something

the shape has changed totally

and now we're getting a more interesting shape

right now see

how this looks just way way way better

I'm going to do the same for the other two here

that does noise intensity to 1

and now we're getting some more interesting shape so

right now just like that in just a few steps

we have some much more interesting clouds already

I'm going to change the tiling or the seed rather

right here and

let's go back to the ground level

and see how this looks

so now I'm gonna uncheck the

show debug

and now we have

full control

over the very position of all our clouds and our scene

now let's say for example you know

it's cool that we can play the cloud but

we still want to have a bit more control over

the look of deep cloud we want to push it even further

so there's two things you can do

we can go back to our

volumetric cloud actor here and play around with

the height of our clouds you know the bottom layer

the height of them how tall the clouds are like this

you can choose there's no right or wrong setting here

you can do whatever you think looks best

but we're going to do here

we're going to select the volumetric cloud actor again

and edit

this material

okay so again like I showed you earlier we can kind of

choose like the density of this material

we can affect the detail a bit how much

detail there is

there's a whole plethora of different settings

again there's no right or wrong answer

you're going to have to

be the judge and just chew what you think looks best

okay now just keep in mind

the Cloud Mask object blueprint here

decides this directly

affects how your clouds look right

so I'm scaling these up or down

moving around

this has a huge and tremendous impact on

the look of your scene

so you'll notice

there's a whole bunch more materials here

let's go ahead and see

the name of them

you'll notice that some of them are called

for example profiles

paint clouds okay so any of the materials that have

underscore paint clouds in the material name

they're not going to work by default

you're going to need to tweet the master material for

this to work with the Cloud Mask objects okay

and the reason for that is because

these Paint Cloud materials are made for

another type of

cloud painting

which is outside the scope of this tutorial

so let's see what happened if I you know drag this

paint

cloud material onto our volumetric cloud material

okay I got a drag drag and drop it here

and okay our clouds look different

but you'll notice if I move the cloud mask

object around

we're not affecting the look of our sky anymore

it doesn't have any effect on the position of our cloud

we've lost that ability

how do we fix this

I'm going to show you how to change

this material so that

this works with the cloud mask object okay so

what we're going to do is

you can feel free to duplicate those materials

that you don't overwrite the original

I'm just going to show you guys

what you need to change

in order to get the Cloud Mask objects

to work with these materials

so I gotta open up this master material here

and you'll notice that it is a cluster

it is such a mess of spaghetti noodles

but don't worry

there's only one thing we need to change

and let's go here

you'll see there's a texture object right here called t

Cloud Mask Storm

okay right up here zoom in right here

this is the texture we need to change

you're gonna find that in volumetric content

we're gonna go to tools

cloud compositing

render targets and why is that because

what these

blueprints are doing the Cloud Mask blueprint

is that they're creating a render target

basically

this is what drives the position of the clouds

so you'll see right here we got RT

underscore cloud mask underscore 01

let's drag and drop this in here

we're going to replace that texture

and hit save in the master material

I'm gonna close this

and now finally now we can move our clouds around

now you'll notice they kind of look pretty bad

don't worry we can tweak this

there's lots that we can change again

so I'm going to

open up that material again

by going to my volumetric cloud

but I'm gonna make a material instance of the paint

clouds so that we just changed right

so right click

create Material instance

and drag the material instance into our

volumetric cloud material

I'm going to open up this instance

so we have a much simpler

menu to work with

and now I'm going to tweet the bias

bottom noise

again God there's no right or wrong answer

there's no right or wrong setting to you

that all depends on what you

want in your scene okay I just want to show you guys

how we can tweet these materials

how we can affect the look of our clouds

so you know don't

bother with trying to get the exact setting here

because they're kind of irrelevant

you're going to have to go

around and play with this

to get the look that you want

now we have full control over

the position of our clouds again

and you'll notice they look they look pretty different

and I think these look pretty cool

so again if you

I'm noticing that they feel a little bit too tall

too stretched vertically

so what I'm going to do is I'm going to change

the layer height

and kind of bring you down to a more reasonable level

and in our cloud mask object

I'm going to play around with the

noise feed again

annoy tiling something like that

and just like that we're trying to get a bit more

control over the look of our scene

I've got to duplicate this

maybe even scale this guy even way bigger

and you'll notice that just like that it is easier than

ever to really art

direct your clouds or your

skies the way that you want them to look

I hope this is making a little bit of sense

I know it's a lot of information to take in

but I'm going to

delete all this and redo it from scratch

just so you guys can get

a recap of what you need to do

so I'm going to select everything here

and delete that and delete my volumetric clouds

done start from scratch one more time

so we're going to add another volumetric cloud here

and again

we need to go back and play with our new blueprints

which is going to be in volumetric content

if you don't have

this folder here

don't forget to go enable show engine content

and then we're going to go to the tools

Cloud compositing

blueprints Cloud Mac object Cloud Mac Generator

Cloud Mac object I'm gonna

move this guy way head to heck back

and the last thing we need to do now

is set the scale like 25 or something

and now we just need to change

the material on our volumetric cloud actor

so I'm going to go find that in

volumetric content

content sky materials and I'm going to use profiles

billowy

try this here

and just like that now we're starting to get something

a bit more interesting

it's really simple that it works out of the box

there's not that much to change

there's no master materials or

complex materials to set up

this works pretty darn well out of the box

you can get them very stylized looks too

and again let's go into a

bird's eye view to get a better

look at what we're doing here

something like that

and I'm going to change of course the

noise intensity of my

cloud mask object to 1 to break this up even further

same with this thing

to 1 break it up further

and now now we have better even better control

over the look of our material

now again I don't like how tall these are

so I'm going to go to the volume at your

cloud and change the

layer height

to kind of bring them down to a more reasonable level

and we're starting to get some pretty nice looking

clouds here so I hope this kind of makes sense

I know it's like I said I know it's a lot to take in

but now

getting the exact look that you want

is easier than ever

having the ability to position clouds the way you want

makes such a big impact

when you're really trying to

get a shot to look really good

you got your camera all set up and you just want the

cloud to look perfect

this is the way to do it

now just one last

bonus tip for you guys

in the event that you want to delete your clouds

what you need to do is select your cloud mask objects

delete them

but you'll see hey my clouds are still there

how do I get rid of them

you just need to go to your cloud math generator

in your outliner right here

and you'll see right here where it says renderclouds

and by clicking that it's going to update

your render targets

and all the clouds that you deleted will be gone

it's really as simple as that

and that concludes yet another video
