hello today I'll be showing you how to introduce

nuke into your blender workflow

so first of all why nuke

well nuke is the industry standard compositing program

and it is used on almost every movie you can think of

such as the lega movies the things I try to recreate

and nuke gives you so much power

but there aren't any really

really good tutorials on how to set up

nuke for blender properly

today I'll be showing you how to set your

blender file for perfect compatibility

in nuke and sanding with your nuke settings

I'll also be showing off my basic nuke script

that I would do

a script by the way

a node tree which is what they call it in nuke

so some of the main

effects will be teaching how to use in

nuke from your blender file

and how to set it all up is adding your mispass

adding in depth

field inside of nuke instead of blender

so that

blender doesn't denoise it and make it look a little

smudgy auto lens flares

similar to how The Lego Batman Movie did it

adding chromatic aberration

color correction

and vignetting and also

changing the color space into aces

so let's get right into it

so the first thing is that you should download nuke

now when you go to the nuke website you will find

that it is very

expensive and there is a workaround

you may see this and think oh my god I cannot

pay for this is not worth it

I can just use any alternative

but if you scroll down far enough

on their page you can find

nuknoncommercial

you can click find out more and in here it has

a page where you can get nuknon commercial

so if you scroll down the page

you find button says get

nuknoncommercial

from here it'll bring you to

a page where you have to fill all this information

about what you do and what you use it for

so that you are qualified to use it

and then you'll be able to download it

you've downloaded from this page

and you download for or whatever

you have

I have a Windows computer but if you have a Mac

get the Mac one if you have a Linux

get the Linux one

so this tutorial will be using the Windows one

just click on that and it should download

so once it's done downloading

should we download it as a zip

as you can see right here

what you got to do is you can

click extract all

and it will extract it into a folder like this

now in this folder

you can double click it and basically

just do all this

you say yes next next next and then install

I've already got it installed

so that won't be a problem

now once it's done downloading you can find it

strip nuke you may see a million

shortcuts on your desktop

but if you go in here you also may

sign a million of them

you're gonna have to look for the non commercial one

so nuke 13.1 V3

whatever

version is out at the time you're watching this

tutorial and it says non commercial

that's the one you're going to need

make sure does not say Nuke X or anything weird

so when you open it it will start opening

if you start off with this

don't close that leave it open

and you can see here it is in

so now when you first open nuke it should

ask you for a license for me I already have it in

and if I recall correctively you either have to log in

or you just have to find the subscription ID

so for example make sure

you have a boundary account here

you can just go to your top right my account

go to my products go to nuke

show contents view your entitlement

so from here you can find the

subscription ID if you need it

so hopefully it all worked out

maybe you might have to wait or there to until you can

activate it

I know some people have had some problems with it

but just

do some troubleshooting search up online for some

ways to fix it

so we now have

nuke downloaded and opened

so there's no need right now for us to have

nuke open here

so I recommend pinning nuke to your taskbar

so you know which version you need and just close it

good job you've just installed NIT

the next step is now to

open whatever blender file you

have that you want to test out

for this tutorial I'll be using a work in progress

scene I've been working on for a new video

don't ask what it is

I don't want to spoil it for anyone

so I'm gonna choose a good shot for an example

we'll be using this shot right here

so let's show you how to set up your blender file

it's not much you have to do apart from

these few things

so first thing you got to do to set your blender

file for Nook is go to your output properties and

switch the file format to open

EXR multi layer

don't worry it won't be that big

of a file if you follow these few steps

so please listen carefully

make sure to choose whatever color you need

for this one I already have a Sky

HDRI so there's no need for me to switch it to RGBA

so I just said it's RGB

rgba is if you want transparency in the background

if you already set it

up here in film color depth I just left

leave it to default

and this is the important part switch the Kodak to d W

a a it is

lossy and it is a lossy Kodak

now don't be worried you don't even notice a

single difference athletes

I have never noticed the difference between this

and with none

and with that you should be all good

now as you see here it's a multi layer

so if you go to your view layer properties right here

this is where you can enable different view layers

few we need for sure to have is the combined and the Z

the Z is that we can enable depth of field later on

so basically

if you have Volumetrics I recommend turning them off

if you want them on

make a separate render pass in Eevee

or you will then later combine the Z

pass in the mispath

from the EV into your cycles pass in nuke

so you can properly use a

nuke with it as a volume metrics with cycles X

now break the Z pass at least that's what I've noticed

so I'm gonna have the volume metrics off

and yeah so if you want missed

make sure to enable missed right here

and also I recommend having denoising

really matters on your case if you really

have time for a lot of samples

but I use open image denoise

albedo normal and accurate

and also with this if you use it

you also get a pass that will say

noisy and nuke

so just in case you want that you can use it

so with all that we can now hit render

now come back after it's done

and we'll show you what to do with nuke

also this might be an issue I've had recently with

Cycles X and my

mecharex workflow is that they

totally break the miss channel

so that's something you'd have to use

EV to create and hopefully it didn't break the

depth channel

so now you have your finished render

unless you're using the render animation

you have to manually go to save

and then you gotta save it to wherever you need it

I'll be saving it in

this folder called tutorial we'll call it based great

I'm just going to keep this here

so that we can compare it later

now do your first job here which was opening up

nuke once again

and there we go

all right great so now you see this right here

this automatically makes you a new file

so you'll be all good to go

also one important thing about the non commercial

version of a nuke is that there's a limit of

1920 by 1080p

of the resolution of your output

one way you get around it is you can

make different tiles

that you can combine later in

any editing

software you do

or if you want to do a portrait video you can rotate a

nuke and then rotate it back

your editing software

just some quick ways to get around it

apart from that the non commercial version

nuke shouldn't

cause you any problems

so first thing you got to do in

nuke is go to edit product settings

we're going to be setting up a few main things

so set the full size format to the size of your render

so here it is 1920 by 1080p

just to just make things easier later on

if anything weird happens

so one main things I like to use aces

you don't need aces in blender

you only need aces in nuke

it's because we're getting a linear

color space output from blender

so that means that it's linear

and we just got to convert it to a proper color space

so I recommend using aces because it can handle

everything really well

according to The Lego Movie

it's because it handles saturation really well

I watch a like the hour long video

that one of the guys who worked on it talked about

why they use aces

so it handles high saturation stuff really well

so switch your color management to OCIO

up here and then OCIO conflict to aces 1.1

and everything else

if it looks the same like this on your end

it should be good

and you can just close

this project settings right here

and if you have

any troubles using nuke

recommend searching up some basic tutorials

there aren't many but just try to find one that's good

if I find one I'll put in the description below

okay now just save your nuke project file

by clicking Ctrl s

it's pretty bad

File Explorer here

but you can figure it out like go

into home and get to your desktop through here

and if I can find the tutorial folder

I'll put in here and name it

click enter and it should save it there

so now if you want to know if you save nuke or not

since the last time you did

you can just check up here right now

and we know it's

been saved since last time

but if I do anything like that

and it now says modified it click control s to save

it will now be all good

so we're going to start off by getting in our render

okay so you got to locate your render here

it's a single

EXR file but if it's an animation

what you got to do is find the folder

and drag the folder into nuke like that

and it will automatically import the animation

but for here we can just

open here and import the EXR by dragging it in like so

and it imports it automatically

now it will automatically handle the

file format itself with Seen Linear which is correct

now first step is to plug this into your viewer

and you see that there's nothing visible

don't worry it will be all good just give me a second

so we got the

EXR file in here and it's working all good

but why don't we see anything

well because we have to add a shuffle node to specify

which channel we want to see

from the EXR file as it's multi layer

so a quick way to search for a node is click tab

and we're going to be searching for the shuffle node

and you can

type in the name of whatever node you need to gap

so for resistance we need to get the shuffle node

so you click on that and automatically put it here

if you have the read node selected

all right great

I did a shuffle node but I don't see anything yet

well you gotta do a little bit more

so now you have to go up here to the shuffle properties

if you don't see the properties

panel of the node that you need to edit up here

any time the tutorial

just double click on the node inside your

little node graph

so I double click on it here and now it's up here

because if I close it I can double click on it

and now it's up there

so make a visual switcher

input layer 2 view layer combined

and there we go

we can see what we saw in blender with a t bit

different color

because it's fully linear inside of Nook

you can move around in here with your middle mouse

click and zoom in

with scroll and

click middle mouse click to reset it

and you also drag these panels like this

now we got to make it work properly

the colors

seem low off and it's not converted to aces yet

it's still on the linear

color space so to make it into the aces color

space we're gonna add in a node called the OCIO

color

space node it allow you to convert the color space

into whatever you want to be from

whatever it is

so for this instance we're going to add it in here

by clicking tab type in OCIO color space

click enter and it should put it in

now double click on it if it isn't up there

so we got to specify what we're inputting

and what we're outputting

so since we know it's from blender we know it's an srgb

linear color space

so to find that go to go to here

the input drop down search it to utility and find

utility linear srgb

and now you can choose the output color space

so to choose one go to the color spaces

and go to aces and choose one of these

the ones are actually good

or at least that work well are aces 2065 1

which I use for my

show Morgan called Dice Quest

so CC do not use CC

as seen it looks like that

do not use CCT it looks like that do not use proxy

it looks like

that and you can use aces CG

for today we're gonna be using aces CG

like they did in the like a Batman movie

see it already looks pretty nice

which is mostly carried by my lighting

but let's see what we can do now

so now I'm gonna be setting up a node

so that you can actually

output the composite that you make in nuke

just in case you don't want to do anything else to it

so simply click tab and add in a right node

now if you weren't select down the OCIO color space

you can just drag the right node into here

and this right note will give you the ability to

write it to anywhere you want

so now you can make sure it's double clicked on

go to the properties and see file

click on this right here and go to

where the files located

or at least wherever you want to

export it to

I'm putting it to where the folder is of this project

and you can name it right here

can name it to basic

no compositeting we're going to be making a BNG

so add in dot PNG right here

all the signs were almost perfectly chosen

apart from the output transform

you have to switch that to color spaces output

srgb to convert it back

to what a normal image will be like

just like that you can click render and click OK

and it will render it

let's go to our folder and find it

and as you can see right here we got the image

working all nicely

see here we know everything's working properly

great we now have a

basic nuke script for blender workflows

so let me show you how to do a few things

we're gonna be starting off by doing

basic effects like adding in a mispass

so let's add that

first thing is we gotta get our mist layer from our

image and the way we do that is by adding in another

shuffle node click tab shuffle and there we go

the way you can plug in the image is by grabbing the B

from the shuffle here

drag it into the image node

and to keep everything organized

you can click control

you see these yellow points

you can click on one

and create a new point on one of these

connections and you can organize it much better

I recommend keeping

your scripts organized or also become a mess

very quickly and hard

to understand

I recommend closing other properties of other notes

to make it easier for you to deal with

so yeah we're going to double click on this

and we're going to

switch the input layer to

mist and we're going to be plugging this into the red

you can switch this

but just make this simple for everyone

we're going to just keep as RGBA and just

plug into the bread channel

but say you want to preview it

you don't want to manually drag that in but hey

you can't even see it

well

all you want to do is select the node you want to see

and click 1 on it

automatically connected to the viewer node

and also if you want deactivated node you can click d

on it and node deactivate it and it's

z areo deactivating the color space

so we're gonna go back over here to the shuffle node

and we're gonna be

showing you how to add a basic merge node

so we're gonna actually go down here to underneath the

OCIO color

space and click tab search for the merge node

add that in and place it roughly here

and there we go we now have a merge node

you'll see two inputs we have a

and a B and also over on the side here it will be

a input that's unnamed to you

pull it out called mask

I wear a mask with a smile

drag that into the shuffle too

so we're going to preview the

right node again so we can see

what's happening in the tree

and we're going to double click on the merge node

so that we can

switch some settings so first thing first

we know our shuffle node puts the Myst into the

red channel so in our merge

node properties switch the mask right here

the drop down to our GBA red

just like that you can see it's mixing it properly

but I don't think this is what you want

the mist should be happening back there not

on the things you want in focus

so a way these mergement nodes work is that

B is the main layer in a

is what's effect again

so I'm going to unplug the a by pulling on it like so

and grabbing the B and plugging that into it

and just like that you can see this

this is now putting this on the base

and now it may look like nothing is happening

so now we got to figure out a way to

put something in the a input so we can actually

merge something

so what we're going to do here is get

a node called constant

a constant here is

node that allows us to choose a color

so we're going to search down to RGBA

and we got to choose a color

this isn't the easiest way to switch colors

and also to see the color

you can see it right here and click 1 on it

so switch the colors here

it doesn't seem so easy

but there's a simple little button on the right

this color wheel you can click on and open up this

so to controls color wheel you can use right

click on the inside of it

move it to the left or right to change

the value set

so you can be really bright and it can go over the 1

setting because it's using your color space

so we're going to be

setting out a color that will look nice

like this

and we also can hold left click in here and change

the saturation

and the hue by rotating it around

like so but

what I would do for this is just use it for saturation

use this little knob right here for the hue

and just change saturation like that

yeah I'm going to choose something that's a dark

blue color to plug it into it

make sure the Alvair is set to 1 to avoid any problem

so we're going to grab this a

little arrow and plug into the constant and then

click on 1 on right again to see it

we can see it's working

so if we select the merge node and click d

see how it's affecting it

and also if you want to change how

powerful it is

you can use a slider right here that says mix

and I'm going to switch it to 0.5

so you can also see it how it is with 0

1.5 is good for me

it blends the ground

pretty nicely as I don't have a like a ground yet

so just like that you have a mispass combined with it

you also by the way can just

make it white

but I'm just gonna use this color

because usually miss is white

but I like to use it stylistically

now we're going to be moving on

into a more advanced part of this that you can do

is depth of field

so we can avoid the denoiser

smudging all of our nice Boca

and doing it all a nuke instead

so we can have a clean

denoise image with no bokeh and then

nuke began to bokeh

now first things first when you rendered

make sure you didn't have depth of field

on your camera

enabled or else you

just can't do this as it breaks completely

so to do this

make sure we still have a right node of on our view

and click tab on our merge node and search for zdfocus

that's the node that will do all the nice stuff for us

as you see here it's not really doing any nice things

yet so we got a few things we got to do for it

so what you got to do is switch the channels to RGB

you have to switch the depth channel to the

view layerdepth dot z

and with that we can switch the math to depth

and we can drag this little focal point right here

you see into where we want it

we're gonna focus on our little guy over here

and you see it is working

we have this out of focus and this guy is in focus

so there's some more settings we can look at

we're gonna switch this output here

so we can see what we're doing into focal plane setup

go right here

means it's in focus

and if we change the depth of fields we'll see that

we can change how much is in focus

so if you want to make even bigger

you can send it to 10 or to 5 you can just put in

numbers by yourself to make it bigger

but here green is even more in focus I believe

because if you zoom in here you already see low green

but we up the depth of field that's our low transition

so I'm gonna have it on his face

turn up the depth of field to have him fully in focus

so we'd avoid any issues that could happen

so this is an issue that can happen and the way to

fix this is just by creating an EV

render pass for these Z

and that one should have no problems unlike this

this won't be too visible though

search the output back to result

if you're happy with you have here

so back to results and you can see this

now it's focused properly you got all women focus and

this boy is blurred out

also one thing is blur inside

thing is to help smoothen the transition

I recommend unchecking it

unless it's something noticeable that you might see

that might affect

the feel of it so I recommend just

having bluer inside off

alright so now we can change

the size of the depth of field but to do that

switch the maximum to

max to like 100 and you can change

the size of your depth of the build right here

so you can just change it to something high

and if you want to make it bigger

you can change the number in here

I'm going to set it like

30 just for a more dramatic focus

okay so now that looks pretty good

but

I want to put in a custom Boca to give it some realism

so to do that so find a bouquet lens

but basically once you have it

you're going to drag it into here

so right here I have minor here

this is called bouquet 12

and what you can do is set inputs for the matte paint

so that's what we got

that's going to be plugging into our TVD focus into a

filter here

and to actually set as Vocas

switch the filter type to image

and click use input channels

switch the image filtered impulse and that should be

good now so with this we can see it here a little bit

and now if you want to make it and a morphic bouquet

all you got to simply do is

add in a transform node right here

if you click 1 on it you can specify

you can see just this

you can click on this tube as of the scale and set the

height to 2

just like that it should create a stretched up one

it works and you can see it

we can

scale that up a little bit

and there we go

we got some anamorphic bouquet right there

so that's how you add in depth of field

I'm going to be now showing you how to add in some

lens flares also known as autoflare

you find the description below and

it's based off of the Lego Batman movies

auto flare node and

go to their drive link

all you got to do is select all this text

so take a little bit

and Ctrl C and go to your

nuke and make sure you have nothing selected

and click Ctrl V

just like that

it'll paste it in a note that's not even from nuke

it's pretty awesome

so now we're gonna be showing you how to set it up

first things first

grab the source arrow

put it to the CD focus and that will be

the main part you need to do

we're gonna be dragging these down

a little bit and we're gonna add in a new merge node

and in this merge node plug it in right here

and you see you automatically put that in the B

and we're going to grab this a

and put it into the auto flare

just like that

we have some

weird looking flares

why does it look so weird maybe asking

well let me just solve in

after we do this click control and there you go

now looks nice

so go to the image

you want to change something very important

switch to operation 2 plus

just like that it is now properly being added to

an image make sure to remove the

transform properties so that you can

take away that weird thing that rear circle

say I think the focal point goes to the video focus

and you see here you can change the mix right here

and you can change how effective they are

so I'm going to set this for like 2.2

and you can just do that change it

and that's how you add in some lens flares

it looks really nice

and I recommend using it

especially with the Lego stuff

also I'm going to show you how to change the

exposure realistically

so click tab search for the

exposure node

add that in and we're going to put it in

after the OCIO color space

right here

and double click on it with this node to use it

switch the adjust in to stops and now you're all good

so let's test it out

I recommend not having autoflayers on

when doing composing

same thing that the field at least

but you can change the exposure

it is actually very realistically done

especially with aces

you can see when it turns up

it looks really good

still and doesn't make it look bad

because if we remove our aces color space transfer

it looks like that

and my God I've never seen something looks so bad

like it does not make sense

it's just so weird

so that's why we put it on

it really makes a lot more sense to it

so for this I'm gonna just leave it to 0

I don't need it for the

shot and you can disable it as well

so I'm gonna do that

I'm gonna get back to where we were

by renabling the field the renabling the lens fires

after all that I'm gonna be adding in some

color grating

this is what I

end up using

I mess with the white point here because it's

the cleanest one to mess with in the gain

to change color

so I click on the color wheel beside

those two and you can change

the color

the white point

so we can really just

mess with the colors and then change the gain color

and just like that you can just totally change the

of your image

now it feels like the matrix or something similar

all right so next up I'm just going to disable that

because I don't want to mess with that

I'm going to be showing you how to add

chromatic operation

so the way we do it is pretty simple

when we separating the RG

and B channels and then recombining RGB channels

but what we're going to do is we're going to distort

one of the channels so that when we combine them again

you have a cool colored

edge around the

edges of the screen

so to do that I'm gonna be adding in

the shuffle node and

just copy it and then undeselect it and just

paste two of them over here

make sure you unselect every time

so you don't put it in an accident

and then you can just

plug them both in here

or what I would like to do to organize this is to

make one right here

and just plug these into that one

and create points here and a point here

and we have a good thing going on here

so now double click on the first one

and unlock everything

apart from the red and the alpha

then the second one unblock everything

but the green and alpha

and the last one unblock everything

but the blue and alpha

and just like that we have these

separate passes of each color

and then we're gonna just create

some more shuffle notes

combine them all again so shuffle and then another

shuffle node underneath that one which

we're gonna combine here so we're gonna put in

B which would be this one then a

would be this one

and we're gonna close all these other ones

we don't get lost

and inside of this first one

we're gonna be plugging in so N a

R G B a so we're gonna unplug all these

and just plug in the green into the green from this

make sure the f is also plugged in and the red

and then for the next one we're going to do

the same thing but plug this one

into the a switch this to a RGBA

plug in the blue in there boom

boom

and we get it all combined again

as you can test it by boom boom they're the same

so boom boom

so I'm just gonna

organize that and now we're gonna do the

main part for the whole chromatic operations that

we actually see it different

and what we're gonna do we're gonna

click on the first one on the left

which is the red one

then click tab and add in a lent distortion node

I'm going to drag that down here

double click on it what I did for mine was

I use default settings

they should be all good

and just switch the denominator here

to what you like so

make sure it goes to a negative and just like that

we have a really strong chromatic aberration

and finally

we're going to be showing you how to add a Vignyep

to all of this

go to the description below

we're going to go here so you can see what I can do

and we're going to

click this open this page

and just click plain text copy it all Ctrl C

go back to new Ctrl v

you now have a fignette node

drag it right here and just like that it works

double click on it and you can change some stuff here

if you go into project settings and your

size format is not the same as the actual output

that you are at least your render

then the vignette will be weird so here it does that

which we don't want at least I don't think you do

so just make sure it's the same as your render

you can click preview you can

freeview it look like

and just change it to your desired here

right now it's just like a circle so

I'm gonna add in some squash to point like 5

softness and if you disable a preview

go boom and search the mix here

and turn it down or up I set to point 6

and there we go we have a final composite

and if you want with color

and don't forget you can just render right here

so now we're done and we're just gonna

change the name to to

just compositing

and also if it's an animation

you can switch list to input and

set the timeline to the right range

so the range of your image sequence

and if we open the image

this is before

that's after it's such a beautiful change
