in this video we're gonna take a look at
be ready for nukes ability to go from
nothing to a rendered element in a
really short amount of time we'll also
take a look at the v-ray material
preview node and how you can rapidly
develop a look of a shader using just
the period material node or the shading
Network you'd great and the berating
material preview without having to setup
an entire scene so another really cool
feature of v-ray for nuke is the v-ray
material preview in this node the
defaults are to provide a preview HDR
and a preview geometry you can change
the geometry the HDR and even the
lighting style and even the format to
make it higher resolution if you want to
see more detail so let's change the
geometry to cloth and the HDR to sunset
to will change the format to 512 and so
now that I have that setup I can jump
straight into developing a look in my
material without having to setup any
other nodes so for this V red material
I'll change the diffuse color to a value
of 1 for red and point to 5 for green
and blue and then I'll add a little bit
of a reflection in we're good to go so
now I'll set up a proper V racing so I'm
setting up the same scene that I set up
in the first QuickStart tutorial these
are some basic nodes and so the values
are appropriate for this particular
geometry that I'm going to be using I'm
also loading in an HDR for my v-ray
light dome
and cleaning up the scene a bit so we
can have exactly what we want to see so
now I've got some geometry and a HD are
feeding into a light dome now we can
start to play with materials so now I
had a v-ray material in a apply material
and I'm gonna label these rust and I'll
add a second v-ray material and label
this metal duplicate the apply material
I'll apply the rest material to the
frames and the metal to the sphere so
now we'll start to modify the materials
we'll set a light rest color for the
frames and we'll add a darker rest color
for the sphere so now that I know that
these two materials are assigned to the
geometry I want I'm gonna go through
here and make some changes so I'll
change this to be labeled paint and
change it to a blue color and then I'll
add an additional v-ray material and
I'll call this metal so the powerful
thing about v-ray is being able to blend
materials
so let's add a texture to do that
blending so I'm going to select two
textures here I want the bomb link when
I have the correct texture which is the
sphere mastery so I can now take the
rest and metal and blend them with our
texture then we get to see some variants
in the two and our metals not quite
reflective enough so let's turn on some
reflection and let's change the
reflection gloss into this which makes
the reflection less sharp so that's
starting to look really good but I'd
like to see some bump to it some breakup
so we'll add the v-ray material bump and
we'll plug in the texture now that might
be a bit too much so let's tone the
multiplier down and that's starting to
look really good
so now we'll work on the sphere a little
bit we'll add another metal and again
let's add a v-ray material blend then
we'll mix in the metal and then we'll
mix that in with a mask
my second texture will swap the inputs
by selecting shift X yeah that's
starting to look really good let's
change a little bit of the values here
on the metal
give it a little bit of color little too
much red though yeah
and with this meadow we'll want to bump
up the reflection color and then we'll
change the highlight glossiness to be a
little less sharp so again let's add a
v-ray material bump and plug-in a mask
and because I want to will want to
probably color correct these two
separately in the comp a little bit
later since we're already in the comp it
will add a v-ray material wrapper and
set our material ID for that one for
that one and then we'll out of the array
render element to our scene want that to
be our ultimate that object is one no to
check they use material IDs checkbox and
there we get on that and as we go
through our layers we can also add
another beer a render element
or add defuse
and of course we'll want Hardy deaths
now we can see those channels and our
viewer this for cleanup will make this
be you ready no element seen check out
the diffuse color and the selection in
our specular so once we have a set of
v-ray at render elements we'd like we
can group those into a toolset so we'll
call that the array channels and then if
we want to bring that in and another
scene we can just say beer a channels in
our tool sets and that brings us in that
selection of elements and we can just
pop in here and update our multi matte
if we want to change colors and what
channels it's called so we've taken a
look at the v-ray material preview and
then also building an entire scene from
scratch using v-ray proxy node
we're a material nodes a texture for a
couple of the pieces of geometry and the
v-ray render elements
