Creating an asteroid field in space!

This video shows you how to make use of particles and other techniques to quickly make a space flight through asteroids. This video covers 3D basics in nuke like particles, sprites and rendering.

The different things covered in this video include
• Planning the shot & collecting resources
• Blocking out the shot in Nuke
• Setting up the particle emitter
• Creating the asteroid particles & assigning textures
• Create channels that drive particle properties
• Dust cloud using particles, modulating the color and other properties using textures
• Rendering techniques for similar shots.

hola their own welcome to: Socceroo
this video is a part for the space
series
and this one I'm going to show you how
to create a flight
through an asteroid belt so the main
things you're going to find a studio
knows how to work with particles how to
animate
from different objects how to control
the particles using the smaller objects
a couple of techniques on animation and
rendering particles so let's get started
okay guy so I'm going to first start by
creating go
love story would explain my shot I want
to start with
or complete starfield the top screen or
the 3d elements
hand and the camera starts to turn up
there for you can see the stuff in
weaned on what's
now when the camera tilts up I want an
asteroid field
to come into view from the top next the
camera starts to
dali in what's and wanted store
da lead in wats you can see that they
interact asteroid field house for dinner
and are shocked
so basically dissident are shop it on to
work on in Nuke
now let me go on break this down to
ensure the different elements in walled
I let me just say that i'm looking at
the entire shot from the side view
so in that case I if my cameras here for
in one
section the star feel is going to be on
the opposite side
and asteroids is going to be exactly in
the central the shock
now first of door camera is going to
start by looking downwards
so they're from a camera is going to
start something this
angle very it's looking only at the star
feat and not at the asteroids
so now the cameras going to first stock
me
upwards and then is going to move
forward so when it's going to rotate or
move upward it's going to take to
has tried to interview and then it moves
in what authorities in
is going to pass through the asteroids
so pretty much does the entire shot
now the different elements in want are
forced image
August our future image I'm going to use
that the backdrop
and also all the asteroid images which
I'm going to use a sprite
in the entire scene so let me just show
you where I'm going to get these images
from
and how I are processed all of them now
coming to the different Rick stone and
resources to have used
the first one his door starfield by
Butch Whitney
on deviantART and the second one is that
passed right back by Hamid
on DeviantArt now both of these
resources are completely free
and you can go ahead and download them
without any memberships
you can find the links for these pages
in the description of the video or on
the website
now after you have downloaded them
the only changed at have to be made
was a disastrous back which are obtained
was basically in one huge
single file so therefore each and every
particular restaurant had to be broken
apart into
its own separate fun so therefore I
haven't heard too
this file into Photoshop and a created
this meet sequence
are with all of these asteroids
individually in their own PNG files
now the reason I did this is because
it's easier to load in all these images
as or single emit sequence rather than
breaking them apart with a nuke
right so basically these are all the
resources
from external sites that I'm using now
we can go ahead
and get started in New now coming to
Newark
to follow along with this tutorial you
should be running new
acts because this tutorial makes heavy
use of particle systems
so once you have it running let's go
into project settings
answered a few things up I already have
are
particularly long name and location set
up for those so I'll go ahead and add
Indies
values and on I want to Santa
more seem to be the shot to be about 10
seconds salt added 22 for the frames
door resolution is going to be hedged E
and also want a proxy scheme to be
14 so that my doesn't hang up on him
trying to recall
no the basic scene is set up
I can go ahead and start blocking are
going to shock
now the main thing you want to do is
block out the entire 3d scene
so let me go ahead and start my creating
a scene no
not connected to my viewer
I'll for screw the camera
now with the camera there
create your cart full actual
background-image:
which is a star feat so Descon
mckinsey value to push it back source in
the background using as you are you
no resemble starfield image which
already have
so that one is pretty much done
no need to create not a card which is
going to be the emitter for the Astros
and RightNow just as a placeholder
I'm going to create home simple spiel
so they can see exactly where it is do
so with the spear
I can move to the sign house killed it
up
K current skill tone
such okay
so as you can see are dark cameras there
my last right fielders deland is mine
image plane at the back
so does pretty much does might really
seem completely now
the next step off to a blocking process
is to animate the camera and how the
basic camera animation
are to ready from this point onwards
itself
so to create this let me go outside the
camera
miles to translate and rotate keys
no I can switch over to the camera
interview for
and control click in the camera icon to
be make it active you I can go ahead and
start setting this up
the way I want thing so the camera
initial frame set up are at around a 53
I want ice refused to be visible so I'll
told the camera parts
K no
with a camera row to tutor I can go to
forty-eight frame
on dali inwards so I am willing to us
the asteroid field
okay now just because I'm not able to
see exactly what's happening
on the viewer can press yes and brings
out the viewer properties
here in 3d I can tell headlamp so I can
said that more 3d Donna can by default
so does use me this result so this is
Danny mission have no
what I can do is ask for the camera
going to the curve editor
as you can see these other
elements I have here so and rotation I
have this very harsh rotations going on
right now so
let me go to Notre Dame sort them out
here
and horizontal on trance lutes
certain to cubic so have a very smooth
transition to different elements
and at the end of a long time to be slow
and beginning on them fast so
your perfect K so no
basically have does house
mean moment to was the asteroid field
but in the beginning I have those
zooming how to fact I created that by
mistake
so I don't really want that so to remove
that I can already take the camera
is a z-axis moment which gives you dot
on in and out moment so I can go on a
date that quite easily here
K done
so no I should not have endured the
moment
perfect now one thing to note here
as you can see there is this plane which
is being blocked out at the bottom out
completely
so I can go take the car and/or
hopefully translate works yes I can
translate it done because at the top in
your way
it's not going to be was a pool after
the so
play after this saw stopping
Kenny perfect
so mentor blocking this done
so this is our cameras and money mission
should
be looking like this gay
has a look at the so one thing I can see
is that the camera justin's upwards
and it just keeps going straight instead
let's say
I want to change that I want a camera to
actually go and look at the last rites
from
Obama so let me select the camera and
398 freemen all
actually more top and ordered the camera
donald's
is so right around 53 minutes going to
be looking or
so what you know how is a camera which
is going to top
move forward and then go down right
saw India and free I want the camera to
become static against so
done in the curve a deterrent is going
to
look at the rotation kors once more
I'll just go home had them or put them
all on cubic
slot see what that gives me okay
done perfect sad this entire scene set
up animated
and ready to go now the next step is are
going to happen creating the astronauts
here
and this region near the spill now to
create these asteroids
I'll just go home and do more small
example here on the site before I put
them in the teen
saw so must return we didn't use a
particulate matter to create them
so let me go huntin put that into see
as you can see the particles are being
emitted from a single point
alderdice fondest no long streak here so
if I wanted them to be emitted from a
single lean or any other object
I can go ahead and take a 3d object and
use that
as the emit input so now I can see the
particles are being emitted from
displaying
right
now let me go ahead and put that as a
flat plane in skillet up
an increasing number of particles issue
what's happening now
9017 Crees it you can see that the room
particles are being emitted to a
particular points
meet other were to cease sold the
release to uniform
and thats not going to look very neat
so not I'm going to go into particle
emitter I'm going to tell a long
the particles emitted north from points
but from faces randomly
so as soon as I do that again see
creates an intact love particles
for me also you can see all the
particles are right now just moving
upwards
sold out who's not really what I want I
want them we know in random directions
so I can tell and direction to be
randomized so therefore they're going to
be random limited from that object
without taking any normal into
consideration
on the Oprah direction no
want to have the setup as you can see
you for
with the particles keep going off how
such I need to drag feel something else
such to make sure they maintain
a particular distance and direction and
such but that's going to get
two TDs so instant what I'm going to do
user
use of rem hold option which is
basically on W puree of frame hold
I can use this connected into my emitter
if I look at this
my sitting deter any particular frame my
particles a frozen on da train
I can move through the time line and the
particles do not get updated
so this is how I'm going to basically
said toe home but if you freeze all the
particles in any
location which I want them no let me go
back into the internal would reduce the
number of particles
their own several
options here to have to work with the
number using particle so first thing I'm
going to increase the velocity read so
have a bit more randomness
so they don't look all mister in one
particular location
100 is a velocity so their much closer
okay no are want to have this
only for one these particles to have any
particular
harsh a personal any kind of detail
I can go ahead and I had them in as the
particle input so as you can see there's
a particle input I can put that in
so let me go out and take a call about
us and put that in this particle
so they can sue those of color bars
everywhere in the scene
no the problem with this is
mean precise it's easier to observe
K know the are this might look quite
neat but the problem with this is that
if your camera actually rotates as you
can see here when it reduced its does
not actually look quite
3d looks kind of use your headache after
a look at it for a while
soul you can't really use it on large
images
so we have to make sure you know exactly
what is happening so these are nothing
but sprites
known for more information please look
at the video which are mentioned or
comment section it's from the foundry to
explain more about
articles no in sort of got a bar
I could have picked any image I want so
21 the Scala boss and I'm going to pick
another one which is a chocobo
I will connect this as another particle
and I do that you can see randomly D
Stewart have been assigned to this
so this is how I can use the same
particle emitter
and connect two different inputs and use
Amandas
so objects here so this is what I'm
going to do with the asteroids
but the problem with creating astral
plane using dis
matters I can't really read in are fifty
different files
at once so instead I'm going to read
them in as a sequence so
go and bring in the last ready-made
sequence opened at in
song for you that interviewer you see
that have different sizes
frustrates 253 frame
and then it stops so basically what I
want the computer to do is go ahead and
use each and every one of these
a different trains second connect this
reno to the particle
enough to come back to the frame or you
can see that
dusts particles have been applied but
the problem with this
are right now is that the pre
multiplication
so I can go ahead just apply Premont and
that you take care of all these
particles
you know no if you can observe that
there are not a lot of variations in the
particles pretty much all of them look
exactly the same
so the reason for that is there a few
options i cant week on the particle
emitter
the way the particle are going to go and
get a sign with this
has tried is that each particle has a
draw number a particular name it is
assigned to it
and that is basically here at the bottom
so no
first thing is telling us no input monus
going to collect the ID number randomly
meaning though
I'll object is going to be a thing to
try and only and it's going to start
at the first frame MERS I don't want to
start at the force freemen randomly keep
assigning them
I want to said randomly so differently
each particle is going to get a random
frame
throughout so that when the sect next
thing is
even the particles a red one thing I
don't want them to add once in steps I
don't want ID to keep changing
I didn't I want them to stay constant
because with frame hold you are not able
to see what the result is going to be
but
to this is what you had to say if you're
particle no
are changing the different I'll whatever
images are saying to them more time
so can just said does known as you can
see how easy
asteroid field which has created no a
few things to note here
we are looking at this feud all these
images are online exactly the way you
had set them up
so if you want to rotate one particular
image you can go ahead and voted
do or general source file itself and to
be rotated here
so let me just show you what I mean I
just got a gastric PNG file
have a player translate K transform
an with us transform added in I can go
ahead and rotate this
and you can see all the astronauts stock
getting rotated as easy as that
so I and obviously the center portion of
this is not set so therefore they are
also clipping in
so this is how I'm going to start
creating the astronauts
no to create don't are asked to reboot
let me go on
and dissenters seen hard the center
section into town
final scene here so hoping to hear
know if I go look at my scene
can see the cameras there my spirit
there's a placeholder
and Astro orders over here no I really
want
blast right over there in that location
so I can hardly go out to cart
more to that location I can make sure
I'm only looking at the current
I can scale it up
K on disable the spear
so I can see what's happening so you can
see door camera is actually moving
through an asteroid field this time
to be able to see you properly let me go
to the particle emitter and increased or
skew the particle size of the particles
for those can be seen
I'll go into the camera view and back
lay so last rites come into view
and I'm flying through them the first
thing you notice is that there are too
few number of restaurants
I one more I can go to the particle
emitter and increase emission rate
oregon go to the particle frame hold I
think reason to anywhere between the
particle life's or
10 so getting more particles
no K
okay now for the next step
hi fi come out to the 3d scene I can see
that all the particles are evenly
distributed
heart the size does not vary a lot does
very book tour
the sizes are pretty constant what I
want is that the particles which are
very close to the camera to be small
and particles further away from the
camera to just very in science
I want majority of the larger ones to be
exactly in the center
so if I want to do in your dad I need to
be me able to map all those properties
onto the card
are actual card it is a meeting all of
these so if we go
and create mission map to go ahead and
create these properties
so welcome back now create a constant
I look at the constant I does
actually said to the root format wright
also let me go ahead and set it to
or one key resolution picture so right
now it's a black constant
I'll go and apply a radio to those so
this really is exactly the center-right
also let me go out in
push it across completely so it's ok you
radio map
going from the urge to the center I'll
go ahead and put this in as an image on
the card
so no my card has a surreal map applied
throughout not to come back to my 3d
scene
you can see that till
the particles are just being emitted as
normal but no
if I go ahead and tell I wonder scale of
the size of the particles to change
according to any one of these properties
like red collar
immediately door image property the
plane property is being considered
because red color is varying from the
center to the edge
the particles are also going to make is
that the same property
so like this I can go out and start
changing different values
and get different results so similarly
Aiken don't need to know
I don't only change scale I can change
any value so I can you and change a
great
so only in the center how majority of
the particles
an idiot just I
have less so now I can change the
emission rate
so I get more number of particles
and most of those small ones are two
words he adjusts
so now my camera animation is going to
go
two worlds the center okay so let's go
into the camera
lock it in and see the results as you
can see the scale is a bit too high
a country to see what is at the back
some going to reduce the scale of the
particles
K
also to add more random the second
increased
kilby Reince even here so my skin's
change
there too K
now to actually see the
result which I get after rendering let
me go on his calendar and cannot
so don't think this calendar
heart goes into the scene and the camera
gets connected to the camera and a
former
Budos I had this result
so I can play through this and as you
can see it's quite fast
I consider to proxy after saving it once
so you can see it's quite fast
moving through the asteroid field
okay no let's say that
I have those but I want to change any
particular property or
eyelets I wanted a bit more variation or
I wanted a dust cloud R&D is
astronauts because I'll it is there are
going to have a lot of tiny particles
that you can't really see through the
cam
so it should look like dust so I can use
so particles once more to go animate any
kind of dust I want
so let me go to show you how I can make
use of that
just reorganizing a little bit so it
becomes easier no
I'm going to go ahead and create new
particle emitter and this particle
emitter obviously is going to make use
of the same card in order to have
previously
and if I go look through it you'll see
that it's
meeting as default like previously
worked on same settings
so I can go ahead until I wanted to use
faces and I wanted to be randomized
direction
and/or I can go ahead reviews a velocity
abut
increase %uh variation so it creates a
bit more writing
increase emission rate self loads up
articles
but obviously I want or hoskin to be
changed according to you
one of the callers there so this is what
I how solo to these particles which are
coming in
no to create the actual dust system or
the dust what I'm going to do is
basically a plan map
with a lot of noise inside it so dunno
computer actually guys going to use a
lot of sprites
so let's go to create a constant for
those I'll
our concert this back to lorenz so on
this constant
I just seen the colo so it's summer
and the white Range how loud noise also
denies to only give the RGB
and the car is going to be black
changeable
couple of properties riding very Asian
I'll add a radio you forgot the alpha
channel radio can see that it's as a
builder
I'll go to change this so it's game unit
are radio system there
man now I can go up lap remote okay
done so I basically have this map which
is going to be applied on all particles
now so coming back to the particles
second set this as a particle not
hopes know came so now the particles are
a bit too small
so how to increase the size so I'll go
said the size skill to around 10 lot
same
you can see notes the particles have
come in
no do a few things that you can do to
edit
are the transparency of peace I can go
into the radio
this is the one which is giving the
alpha channel I can reduce opacity of
this real to me
them a transparent so also this
2,000-point
all it's a 0.5% so it's a huge
cloud of dust basically sonar for come
back to my scene
and connect the senator
into the scene unity to you just got or
via see does not have a frame hold right
now so I'll just go home
I'll all too cute are basically to
create a duplicate
so how free multiplied into the scene
now dust well I can go ahead and change
the colors on this if I want
let me go to the scanner and check out
what the result looks like
you can see it's basically has a lot of
dust
around the astronauts no if I want to
actually change the color of the
astronauts I can go to a constant and
change the color
but you for want to do it interactively
in the interests of
right here are what I can do is go ahead
unusable and Matt no
again this is explained indoor foundries
particle you can go to that to
understand what's happening
also the surf is blown motor module
eight you can just hover over the
surface plan option to see that modulate
or what does it do multiply its texture
with the vortex cholera so
so now coming to the particle system I
can go
choose any color I want and all the dust
gets that Parliament applied on top of
it so that's the reason I kept or
constant white so that I can actually
add any color I want
right here Saugus 22 blue obviously my
favorite color
blue so blue-collar dust so that is set
as you can see it looks like there is
some fog
and/or has tried actually do fade of
going to it now bother to say that to a
disastrous which are there in the
beginning
are not actually feeding a lot so I want
to go ahead and add it does
K
your your okay there are a lot of
asteroids here in da front which are not
actually fading
so want to go out and it does too so the
gravel
I can do that is a if I come back your
I'll just go chain be of order so I can
actually see it
you can see that all the particles in
the front here are too small
because of which the dust is not able to
cover though has tricks
so I can't really make you the same red
color which %uh views into a previous
particle emitter here at the bottom
in the skill parameter so instead what I
would do
is back in the radio system this radio
how to that I only wanted to give you a
radical so it's going to give me only
read an obscene or the channels
had a new radio and the three DO NOT
is going to give me green so let me just
call
default Asano hopes
okay
so this one I wanted to give me on the
green collar so
by gone by a combination of red and
green getting yellow
what I will tell is that i won to be
very harsh towards the edges
no I have a red channel which is very
soft and have a green channel which is
shop or so with booze if I come back to
the scene
in the particle emitter for the dust I
can go ahead and tell in sort of a red
use a green channel
and as you can see it creates a much
more la brake dust cloud so
if I want to change it I can come back
mind to the
channels to sit or GB and only green I
can go ahead and change this value
till I get something which I like so
let's say I like
deaths I can also use perpetually near
and then changes to a higher value or
so just make sure it looks good to you
right
case I have duce if I come back to my
house carolyn Monroe
harder result is going to be too harsh
because
dial dust clouds visible too much so
back and/or
capacity parameter I'm going to to very
low value as you can see
it has created my dust cloud no the only
other thing I want to do is because it
looks like a straight line
I don't really want a camera to have
that streak look
so back in the camera Hong let's say the
50th remember had dissertations
happening
I does go ahead and add about a few
degrees
to the camera z-axis Mundus plug-in
lots about trial K
now similarly if I come to summer here
as you can see takes a bit of time to
render
so I can go ahead and turn off those up
dust
because that is the one that sticks a
maximum time to render had play here
to see exactly what's going on as you
can see the
nine-term asteroid belt Thomson not
don't and there was a issue because the
plane is no longer covering the entire
section
so I come back to the plane and I'll
increase the size
by a few units just over want
3 for K
strides coming in
hard thing to note your as you can see
there is dis Astra which is very low res
I can see it's pixelated
too much compared to anything else
you're even the one here at the back
it's pixelated too much
the reason for this is that destroyed
map which are created I have even
low-resolution images in their so
because new .cos assigning them randomly
I'll even small images gets killed too
much so that's when you get this issue
you had to go to all of you may just
once more to see whether or not you have
such problems
how can I turn off proxy obviously the
quality will increase so you don't have
to worry about
too much so let's go
played once completely
can ok at the los Primos you can see I
don't really like this composite
I wanted to be a bit different so I come
to the frame which actually has a
keyframe
Gloucester okay to rotate have a
keyframe
and nerd properly
and a translator to the wrong frame I'm
just going to translate keys to the
proper to forty a tramp
so I can edit it all in one location so
here I can go to change values
to see which
would look better K
I really like this asteroid here on the
site so I'm going to keep this
has no final frame well let's go say
once earned produce
in your k beautiful
now as you can see dough into dust cloud
do doesn't really look like it has a lot
of variation so
to get a lot of variations all what you
can do
Mizzou Methodist approx it's too slow so
to get to a lot of variations
what you can do is a back into the noise
not for the
picture here you can increase again
amount
and make it a harsher noise
so you can see a little bit more
variations and also turbulence gives you
good values
CNC it looks better home you can go out
to eat this however you want
till you see what you like okay
so basically not the entire three
the system setup now the next thing is
I'm going to just go ahead do a simple
greed
and finely rendered this out now
because you already know that I like
blue-collar a lot
be making sure that it looks blue MTN so
let me go ahead and add on a great note
here
how conduct that are hired if you don't
want to be working the proxy footage
when I'm trying to create here
Hall in this instance so and is growing
my first thing a turn on the zebra
striping for a near out of government
pixels
and our gonna here the green orders are
in specifically forced her to the black
point in the white point when you do the
left the game and do
follow through the whole process so for
stepped the Black Point
alkyl chains are to a negative value
today getting easy for striping here
and as you can see it's trying to redo
the entire image once more
which is not exactly what I want so let
me actually go ahead I love how big does
major write it out and I can read it in
or
by Candice cash it soul well-known
and cash it saw and a great I can go
Titans start changing this
I need to make sure black plumpers of
for a cycle not be able to see the
results
so begins again see as soon as increase
the black point to its
going off your insights I def need on
one pitch black pixels on any of my
inputs
so what I will do news on the astronaut
to coming in
I'll a black great note here Honda
I'll increase heart here the one thing I
have noticed
left and gain the left walks on the
Blackwell lose and gain walks on the
white
so want to lift the blacks pilots a
point 01
value so all of these become slightly
lighter in color
so therefore there is no which black
writers in Iran I think that's a bit too
much so let me
degrees out
okay so as you can see you can still me
got a lot of details
so perfect
so hot that great added in there
no coming back to the old great
953 could should not go and clam
so easily it should be some values
market that it's done
now for the White Point I need to
brighten it up so that I can how some
hot spots
Sona chain this as you can see there are
some hot pots being created here
so I'm just gonna change it a little bit
okay so black and white ass set
no I can use a lift in game to add in
some kind of perfect
to the shot so I want shadows to be
most likely and bluish site so let me go
to the left
also 22 bluish toll and
increase it a little but saturated more
ok am looking at a particular color so
basically what I did is wrong
per Salam said it's summer here
all do such a route okay so it's dark
bluish in color
and I want the highlights to be warmer
sold and I'll gain I'm where to set this
to
a bitch reddish tone but not too much
know that it's done
no overall I wanted to be blue shinto
nso this
dusk lobby to how I'm going to give it a
much such created blue
so everything has that tone and a
done now
this is pretty much done I can go ahead
and start rendering this out if I want
know one thing I can do is go ahead and
add an extra level of particles small
dos de Vries which are going to make it
look much better
sold actually go ahead and do that once
it is back to proxy
and I'm going to go ahead
create a new particle emitter
K
and let's go look at this and 3d scene
as you can see it's a single straight
line still I want to use dorsey mold and
heater which we had from
lost time so let me go on hoops
and use that as a matter and as you can
see particles are being emitted from
here
I don't want to make use of any
pilots a call mission rate changes
over here with dust I wanted to be
randomized I wanted to use faces
K I'm going to increase emission rate
Alexia
house in so have loads of particles now
I can go use frame hold and I'm going to
hold it on let's say
10th frame so does
the particle which I'm going to be
making use of heart is chained or
velocity range too high so you can see
it's distributed a bit more you only
no these particles I want them to be
are basically a full in particle over
just who's your pick no treaty ish
look so to get that looking right
more discreet and a constant that's
going to give you
crude the smallest size 256 actually
I can go smaller than 256 with us so
let's go Crean you want well called
us about 22 22 prostitute pixels
so it's a very small constant I'll go
play radio
default on
go 00 2222
safe return of proxy considers the
actual
hope to have right now soul
K so this one is done
mind if I come connected to particles
and a particle emitter
look at them here Zimmerman you can see
that these
are basically small little our spirits
going Spears which are visible
I'll go into the particle emitter all
changed or
range full-scale to be about fire sa
very large ones a very small ones
let's look at exactly what's happening
holidays and the scene by
ringling the rest because
so rest are going to take a little bit
of time to render case
so let's go to scalar and render this
out
so you can see the particles a bit too
large for my tastes or go
for you skew for Dez so this is a rare
ismael
my number increasing number of particles
again so basically have a huge dust
cloud
of all these K
also I don't want them to visible too
much I want to be a bit more transparent
so in the radio I'm wondering is all
pasady
not a perfect
so known to have this I can go ahead
connect all the rest
okay sauces are connected at the new
just crashed on me so should be a little
bit more careful
curso let me just go costumes a connect
all of these
say that and unpause
as a consuming you know the particles
Malta
dos all the last rites everything's on
the scene
and it's purely animated it's completely
3d
inside new you can pretty much do
anything you want without
lasting I'm going to do this particles
are
too bright so I can go ahead and resists
capacity of them a little bit more soul
they're just going to add in the fly 3d
element to the scene
K so now one last step
after I have actually created a Twitter
proper black and white values I can
had a color correct on top and he
reckoned treat the shadows and
highlights the way I want
Sol let me go ahead hand again redo a
little bit of the work
so the shadow region
I wanted to be saturated bluish do such
through the rest first
hardiman tones 2012 had in a bit more
calmer
whether bluish tinge K
came now
one last step hope for those of you when
I asked me last time
the stars which you are being used which
we are using basically a maximum of
value
one for the stars they don't go beyond
that Vera's
in real life door stars are actually
pretty bright
so if you want to get that kind of
detail what you can do is add another
color lookup
and what I like doing is in the master
view
I can go home take though brightest
values
and pump them up to around 50 or 60 even
higher
depends on doe look you're going for so
I kept it a one-goal you
turn and now I can go home and clamp the
rest
coming
sunau busy what her who's this star
field in which there are stars which are
brighter than whites or gonna go on top
of them
you should be able to see some points
which are actually brighter than white
here the bottom the child is more than
one us all when you have motion room
they're going to give you some real nice
motion blur
and also those stars visible through the
dust cloud more easily than the rest
so pretty much this is that let me go
have taken off the book of those
handle showed an emission some
done with do creating flip book so let's
see the actual animation
you should be able to see that no dust
clouds
and Astro reading the star fields are
all working pretty well together
home but there isn't there are a couple
of issues like a few asteroids a very
little rest
so their foreign you actually come very
close to them you can see that they're
all pixelated
me to really can be held currently
because
so I actually is a stock footage if you
want good quality it's better to go
ahead and a
classify all your particles into
different sections and have low quality
ones always be small in size
so pretty much I have this entire scene
setup
know one thing you might notice is that
the playback is a bit choppy
there are two main reasons for that to
foster's there is no motion blur and a
shot
and second I'm recording rawr
15 transfer second round at the US
playing back a $24
soul booked these reasons to give you a
choppy foot so
let me just go back into nuke summarize
everything that you know
don't deny and then I'll show you how
you can get rid of the choppiness abut
to
soul back in Nuke desde our final comp I
have so
I let me summarize all the different
elements we have here we had a 3d scene
the to set up
to begin work to be had a scene the
camera and a scanline renderer
we went to had an animated this camera
we have a card which has the cell
simple starfield apply to it as an image
are there is absolutely no shading in
downtown scene so you have a light on
anything as such setup
you need to make sure that to cart is a
meeting although properties
next I hear our data card which are a
couple of
rhymes heart this is basically my
start or all object for all the particle
systems
so therefore it is the one which has
been feeding although other objects
I have a particle system which is are
making use of the ass try to meet
sequence which are created
don't know how other procedural I strong
dust cloud to check created using
completely home using just nuke
now all these are just going in and
amusing scanlon vendor to render them
out on them just
doing some simple color corrections now
yeah it does I was showing you the
choppiness of the video
the main reason for the choppiness is
that there is no motion blur
so let me just show you how you can get
a bit better
motion blur my dream although objects
which are going to take a bit more time
to render
killed me and astronauts
going so now when you have a lot of
movement
in the camera I'll you need to get
motion blur too powerful
good-looking smart footage so to get
this motion blur
instead of adding vector blur you have
to be using
multi sample the reason you to use multi
samples because if you're going to use
victim there because the transparency
information
present in the particles it might give
you some board results
so just for that it's better to have won
t sample take care of it rather than
doing it yourself
soul now if you see there is going to be
a lot a motion blur
were with the camera movement is high
and is going to give you much better
results
so pretty much thats that
you can increase the sample level and
try to get better results
so diets pretty much it for the entire
video
hall what I have shown you in this video
is basically how to create different
particle instances using meet sequences
or any kind of transparent particle
system to
sprite completely within nuke and how to
render a docked
so I hope you found us use video use
Form and I'll
I'll see you in the next one
