NUKE and NUKEX 6.3v7 New Features Video Video Lecture | Create Visual Effects with Nuke - Professional Skills

hi everybody and welcome to this video
taking a look at the brand new features
inside nuke and new KX 6.3 v7 this
release besides of course including a
multitude of bug fixes and speed ups is
going to take a step towards ensuring
better integration and interoperability
with the no doubt diverse range of tools
that you probably have in your current
pipeline now there are going to be four
videos in total most of all taking a
look at our improved layered PSD
handling then the new and frankly
awesome open color io features the
extended render man integration that
we've introduced for nuke x and last but
by no means least the new multi yuddam
functionality which is going to come in
extremely handy to those of you using
mari or the nuke Mari bridge so let's
jump in by first of all taking a look at
what we can now do with those layered
PSD files so whilst you could of course
bring in PSD files in any previous
version of nuke in nuke 63 v7 we vastly
extended that functionality meaning that
you can work closely with your map
painting team with your texturing
artists and avoid that nasty time spent
converting between different file types
which is something I'm pretty sure we
all hate at this point so let's have a
look at this in action so in this comp
as you can tell by my nice blue backdrop
I need a PSD file in fact I needed this
PSD file that i have here now on the
right hand side of the screen you'll see
that it's a pretty standard PSD file
we've got some layers we've got layers
with masks and we've also got a few
adjustment layers as well now whilst you
are still going to have to manually bake
down these adjustment layers we no
longer have to rasterize or bake in
these masks because 637 is going to take
that over for us to use directly within
comp now the other thing quickly before
I switch back to nuke is the fact that
as we can tell by this little 16 up here
this is in fact a 16-bit PSD file and
whereas previously we wouldn't be able
to bring those in a tool we can now
bring those in perfectly within nuke so
I'm going to switch back into Nick and
we're going to go ahead I'm going to hit
our to bring up our read dialogue I'm
going to select my PSD file and click
open to bring it in no if I view this I
can come up to my layers drop-down list
which is this drop down here in the top
left hand corner of the viewer and
inside of here we have access to all of
the layers that we had available within
our PSD file so for instance if I wanted
to view radar front I could select that
we can see the color information here
and if I
a which is something I'm sure you all
know we would view our transparency or
alpha information now a minute ago I
said it brought over those masks as well
so where exactly is it putting that
information for us to use while i'm
going to hit a to toggle back to RGB i'm
going to come up to this drop down here
inside of here what you'll notice is
that why most of these layers have
something like red green blue and alpha
channels some of them are also going to
have a dot mask channel directly within
that layer now this is the rasterized
mask information that's coming over
directly from Photoshop and I'll show
you in a minute exactly how we can use
that so with that darling come up to my
layers list switches back to RGB a now
if you had to manually go through and
shuffle out every single one of those
layers within our PSD file in order to
say manually grade one or two of the
layers within nuke well that's going to
take at least me quite a long time to do
so in 630-7 we've introduced a new bit
of functionality that's going to really
really speed that up for you so I'm
going to grab my PSD file and drag it up
above my comp it just to give us a
little bit of room to play with and then
going to come over to our properties
been in at the very bottom of our read
panel you can see that we've got this
brand-new PSD option section inside
which there is a single button called
breakout layers now when I click this
week's going to go ahead and loop it
through every single layer within that
PSD file separate it out into a nicely
named backdrop which of course is very
very easy to find at this point and
shuffle out that data for us so for
instance if I want to come over and look
at that radar front section you can see
it's very easy to see it's this one here
so at the top here we have the original
PSD file so nothing's going to change in
the viewer but underneath that Nick's
gone ahead and added in a shuttle node
shuffling out the information exactly
like we had before no underneath this
it's added a very important crop node
and this is important because if we
manually merge all of these different
layers together without a crop nuke is
going to have to evaluate every single
thing we see in the frame every single
pixel so 1920 x 1080 for every layer we
have in our PSD file now with the crop
node what's happening is that when we
hit breakout layers nukes looking at the
data that's in that specific layer and
cropping down so we only evaluate
exactly what we need to and this is a
great thing for optimizing render times
later on down your comp dream
so underneath that we have a brand new
node called the PSD merge gizmo and
inside of here you get access to a few
other parameters that are available to
us per layer in the PSD file so if we
open this up and take a look you'll see
that the first one we have access to is
the operation or blending mode and in
here although this is sent automatically
of course by our breakout layers
function we have access to other
blending modes that are available to us
within Photoshop in fact almost all of
them are in here and they match very
closely now underneath operation we have
masks so just like nukes regular merge
node you can of course mask a merge
operation but remember I said that that
rasterized masks data is coming into a
nuclear from Photoshop so that on some
of these layers is also being set
automatically so that foreground mask
channel is being added in here by the
breakout layers now finally underneath
that we have the mix value or the
opacity value per layer coming in from
Photoshop and this is again set
automatically but we now have full
control over this we can animate it put
expressions on it and do whatever we
want here directly within nuke so let's
take a look at the final image I'm going
to come over here and click on my bottom
right most PSD merge file and we should
see the full thing merge together as we
do here now the beauty of nuke doing all
of this work for us is that it's now
much much quicker to go in and make
individual changes on a per layer basis
so let's say we liked this visor hunt at
the top here but we wanted to change it
just slightly we could come in and very
easily find that section so it's this
bit here underneath my crop note I'm
going to start off by putting in a
transform by using the Tiki I can then
come up and whilst viewing my final
result I can just add in something here
like 10 to start moving this up out of
my scene and of course I can come in and
individually start moving that up using
my up and down arrow keys so say you've
done a bit of a transform maybe you want
to put a bit of a grade on there as well
so we could come in maybe start gaining
it down or up to change the look at the
file whilst viewing that final result
again so this is just a quick look at
the improved layered PSD functionality
available to you within nuke and new KX
6.3 v7 version 6.3 v7 of nuke now
supports open color I oh the open source
color management format originally
developed at sony pictures imageworks
for those of you
with the tech ocio enables color
transforms an image display to be
handled in a consistent manner across
multiple applications in your pipeline
it's something that we've introduced
into all of our products here at the
foundry and it's also available in other
industry standard applications such as
silhouette for example so let's take a
quick look at the integration in Duke
itself so as you can see I'm playing
about this footage up here in my viewer
and one of the most important aspects of
that is the color space that we're
applying to the image before it's
displayed on our screen and to effect
that within new core change it we can
use this menu here called the viewer
process menu now inside of here by
default you'll have three options none
srgb and rec 709 however like most
things in nuke this is completely
extensible via Python and gizmos which
explains my custom gamma 2.2 option at
the top of the list however if we start
introducing open color io into the
equation suddenly this menu can become
much more powerful so I'm going to start
off by coming up to my nuke preferences
inside of here i'm going to hop over to
the viewers tablet at the very top we
have three options now kind of
pertaining to the open color io
integration at the very top of the list
we have viewer processed lutz commonly
set to nuke rootlets this describes what
we can currently see within this list
however if I switch this to OC io what
we're going to do is enable the use of
open color I owe lots within the viewer
process drop down now initially this
isn't going to change much because this
second drop-down is set to nuke default
so none srgb in rec 709 however inside
of here we have several other conflicts
or groups of luts that we can use either
/ facility or per project across not
only this application but other ones as
well so let's say we wanted to use these
sony pictures imageworks VFX config i
could click that option and inside of
our viewer process drop-down we now get
access to many many more lutz another
way to use this is to set custom at the
bottom of here and we can now set this
to a config Tosi i/o file inside of
which describes a group of luts again
which is going to change the contents of
our drop down in addition to the
extended view process options that we've
got up here we've also introduced 50 CIO
nodes in 263 v7 so I'm just quickly
going to take you through each one in
turn first of all we have a CDL
transform node which is going to allow
you to apply an ASC
CDL grade by the file input here old to
some of these options and then if you
wish you can export it as a dot CC file
we have the file transform node which is
going to again allow to apply a
transform from a file and if I come up
to the help menu at the top here we'll
see all of the many many different
supported formats in the middle I have a
log conversion node so of course log to
Lin or Lynn to log if you want and this
is using ocio of course over here we
also have a color space note that will
allow you to convert from one color
space to another for example if you were
to turn on the raw checkbox in a read
node this technique could be used to
linearize data using ocio itself and
finally we have ocio display inside
which you can choose a display device in
this case i'm only using my default
screen of course and you can choose the
color space and viewer transform applied
for that display device in the drop-down
so that is the brand new open colosso
port available to you within 63 v7 as
part of nuke x 6.3 v7 we've extended our
render man integration allowing you to
modify or inject rib data from directly
within the comp before passing out to
render time so I'm quickly going to show
you the node will be using for this
overhearing this first example and it is
in fact the modifier rib node now if I
open this up you'll see the inside of
here at the very top we've got three
options that we can set first of all is
the operation mode itself currently set
to object so kind of the global
parameters of the rib node we can also
choose shader replace and world and i'll
be showing you those in a second
secondly we've got archives we can point
directly to a dot rib file if we so
choose and thirdly we have a statements
field so in this case I'm changing the
shading rate of the current renderer the
second example in here is going to be
using this shader operation mode so
let's go look at the final result and
you can see it's pretty much exactly
what we had before the inside the modify
rib node I've changed the operation to
shader and I'm applying the arm marble
shader so if I go ahead and enable this
node of course we change the shader
apply to the object the third mode
available to you is replace and here you
can see we currently have this
checkerboard cube and within our modify
rib node be using the replace mode to
set a color a surface and action
describe some geo in this case a small
sphere so if I go ahead and enable my
modify rib of course we're going to
replace that geometry at render time
this replaced mode however it doesn't
only have to happen on a single object
in this case I've got two objects coming
in a cylinder and a cube and of course
they both have different values so the
cylinder in this case is a little bit
smaller than the cube now at render time
if I go ahead and enable them I modify
rib we're going to get two of exactly
the same spheres that we had before but
also of course be taking those scale
values into account finally over here
I've got the world setting so inside my
modify rib node operation is set to
world and I'm describing a lot of things
in here I just give us a little bit more
space you can see at the very top i'm
defining to point lights underneath
which i'm defining a sphere and then a
torus so with absolutely nothing hooked
into my modify rib node I can view my
final result and see our newly
constructed scene now a good way to
possibly utilize this workflow is to use
proxy geo within your nuke scene and
then switch out at render time so let's
say that we wanted to use something like
this where we've got a proxy robots of
course invading our nukes script what
I'm going to do is allow you to go into
my modify rib node I've hooked up to a
rib archive in here using the mode
replace and at render time if I just
turn this on we're going to go from our
low res robot over to our high res
version so of course this is just one of
the many different ways that you can use
this node but that is a quick look at
the extended render man integration in
Nuuk x6 three of these seven
the next feature I want to take a look
at brand-new to nuke 63 v7 is on multi
yuddam support so in this scene i've got
this model of an anvil but as you can
see it's texturing is looking a little
bit strange and the reason for this is
that the models you v's actually extend
beyond the traditional 021 UV values in
fact in this models case it's 02 for now
in previous versions of Luke there's not
really much that we could do about this
however in 63 v7 we can turn the model
from looking like this to looking like
this in other words textured correctly
on every single UV patch not only in 3d
space but also at render time so I'm
quickly going to come in and delete both
of these nodes so I can do this from
scratch and show you how you would
implement this within your own workflows
so the first thing I want to do is come
up here to this top menu and come down
to you dim import and inside of here we
want to import an image for every single
patch on our object now one thing of
note here is that this number of the
very end of the file name sir 1001 to
1004 although it looks suspiciously like
a frame range in fact it's not this is
what's termed the you dim number and it
describes the patch that that current
image will be applied to so I'm going to
select all of these images I'm going to
click open and we're going to bring up
this dialog which is basically nukes way
of telling us which image its applied to
which patch so in this case we can see
patch 1001 it's gone through the
filename and found that same value so
it's linked these two together and it's
done that of course for the other three
patches as well now just have note in
case you have a different naming scheme
at your own facility you can absolutely
extend this through Python and the
instructions on how to do so or in the
current version of the dev guide at this
point you could potentially go ahead and
use this add files button to bring in
any other images you might want to add
onto the model now in the case of their
you dim numbers being the same so if you
have two files both with this 1001 value
nuke is going to add in something down
here in this conflict line telling you
exactly what it's found and what the
current problem is now at that point you
could come in and disable one of these
if you wanted to so that you only have
one image / UV patch now in this case
I'm going to leave them all enabled
because I know this is a very good setup
that I've got here
going to come down to these bottom two
options now these really affect how the
nodes are going to be displayed in your
comp postage stamp will add a postage
stamp to every one of these read notes
and group nodes is going to take the
entire set up and group it up into a
single node that you can plug then into
your reggio so I'm going to turn both of
them on in this case and come down and
click OK now with that done Luke has
generated us a single group named after
the fall sequence that i was using so in
this case blacksmith anvil i'm going to
hook that into my reggio and as you can
see everything is going to texture
correctly so let's have a quick look
inside of this group and see exactly
what's going on now there's two ways we
can do that first one is to double-click
the group and come up and click on this
s button the second way my personal
favorite is to grab the group and hit
command or ctrl enter so inside the
group itself you can see there's several
things going on here first of all at the
top we've bought in an image a read node
for every single one of those patches
now underneath this we have a new node
called UV tile and inside of here the
script has gone through and
automatically added in that you dim
number for us so 1,001 1,002 etc now if
we wanted to we can manually override
this alternatively disable it and
manually add in a U and V value now in
this case I'm going to toggle that back
on because obviously our texturing is
looking pretty good at this point so
underneath our UV tiles using the merge
material node to merge together every
single one of those patches and finally
at the very bottom we have a brand new
multi texture node which is just
optimizing this setup oath for 3d and
for rendering so that is just a very
quick look at the brand new multi yuddam
support that we have available to us
within nuke 63 v7 of course it's going
to be very useful for those of you using
Mari are using the new kamari bridge and
if you're using a multi you didn't work
flow at your current facility
