welcome to this QuickStart introduction
tutorial for v-ray for rhino in this
video we take a look at rendering a
product design and v-ray for rhino and
how to get productive rendering in no
time
open the scene file single earphone 2.3
DM found in the downloaded assets from
the tutorials webpage linked below now
once you have v-ray for rhino installed
you'll want to switch from the Rhino
render to v-ray by going to the render
menu current renderer and select v-ray
for rhino a floating toolbar appears
that you can dock into the Rhino UI the
toolbar is divided into four tabs the
main tab gives access to the asset
editor a couple of render icons show the
viewer a frame buffer or VfB icon and
edit materials icon we have a tab for
adding lights v-ray objects like an
infinite plane or fur and a couple of
extra tools in the main tab open the
asset editor this is the nerve center
for v-ray for rhino the asset editor is
divided into four sections the materials
which allow you to create and edit all
the viewing materials in the scene as
well as see a material preview here in
this box next is the lights tab that
gives you access to any lights on the
scene then via a geometry tab to add
items in the scenes such as fur and a
last tab is settings to adjust your
render settings here you can share the
VfB with its icon or launch production
or interact renders from here click this
icon to start an interactive render and
it appears in the VfB making adjustments
in the scene will update interactively
in the VfB in the asset editor go to the
materials tab you can click the add
material button to add a new material to
the scene select generic right-click on
the material to bring up a number of
things you can do from applying the
material to copying pasting it to
renaming it and so on
double clicking the name also allows you
to rename that material
name this material cord as we'll be
using this for the earbuds cord select
the cord right click on the cord
material and choose apply material to
selection you can see the VfB update to
eighth grade cord click on the quick
settings tab and we'll get to work
making this look right this tab shows
the core parameters for the material to
make editing easier as well as a
drop-down menu here so you can simply
select the settings from any of these
preset material types
now select plastic from the list the
preview updates as does the cord in the
interactive render and we can change any
of its parameters to suit our needs make
diffuse color a brighter gray adjust the
reflection down a bit and set the
glossiness to 0.85 to diffuse our
reflections a little bit in that plastic
now check this out if you click this
arrow you'll see the material library
expand out to the left there are several
categories of materials shown here
select metal if it isn't already and in
the list of materials find and click on
the silver blurry material and go ahead
and drag it over to the material list
like so select this ring geometry of the
earbud and right click to apply this new
silver material click on the quick
settings tab and reduce the reflection
value and you can see it update here in
the VfB now scroll up in the list of
metal materials in the library and
select the metallic foil green and drag
it into the material list select the
accent Rings geometry in the earbud and
assign the green metal to that select
the plastic category now and find the
plastic simple shiny black material and
drag that into the material list select
the front ear by geometry and assign
this black material to it scroll up a
bit and drag plastic simple grain s
black into the material list and apply
it to the housing of the earbud notice
that the frequency of the texture on
this rough plastic is a little bit too
long
urghhh click on quick settings tab and
scroll down to the bump parameter click
on the map icon to edit the bump map
that is giving us this texture set the
frequency to 30 and we get a more
natural texture on that plastic part
back to the material list to get
something for this large part of the
earbud scroll down to find plastic s s s
0 3 green this has subsurface scattering
in the material that will give us a nice
silicon look drag it into the material
list and assign it to the geometry close
the material library and let's move on
to lighting in the lights tab in the
v-ray toolbar click this icon for a dome
light which will surround your scene and
light and then click here to place the
dome light in the scene now immediately
a file dialog appears asking for an HDR
or high dynamic range image for the dome
light
navigate to the FIR desk spherical HDR
file found in the downloaded assets for
this tutorial and click open this places
an HDR eye panorama as an environmental
light in the scene and the interactive
render shows this click this arrow to
expand out the settings for the light
adjust the intensity value to 2 to give
us a bit more illumination in the scene
expand the options and turn on invisible
so that the HDR does not show up in the
render and then collapse the options in
the asset editor now select a dome light
and go to your top view in rhino rotate
the dome light to just the lighting
direction in the scene until you find a
result that you're happy with
I'll set mine about here and then I'll
go back to the single view in the asset
editor go to the settings section to
tweak our render settings open the
camera roll out and adjust the exposure
value to 8 to allow more light into the
camera making the render brighter next
enable depth of field click the pick
focal point button here and in the scene
click on this part of your earbud model
to set the focus of the camera
there now you can adjust the D focus
value as you see fit for the image i'll
set mine to 0.35 open the render output
section and let's change this to a
square image select the aspect ratio
pulldown menu and choose one-to-one
square you can input your own aspect
ratio by choosing custom but I'll set
mine to be square
now whatever resolution you put into the
width will adjust for the height and
vice-versa I'll put in 640 this does
require me to stop the current
interactive render in the VfB would be
stop button here and to restart a new
one you can see the subtle blurring here
from depth of field and the nice texture
on this rough plastic with this larger
render now expand the environment
rollout so we can put in a backdrop for
the render that won't provide
illumination beyond the dome light that
we already have click on the swatch here
and you'll see that by default it points
to a default Rhino HDR image which I'm
going to replace click here to select a
new image and navigate to background
JPEG found in the downloaded assets for
this tutorial this map automatically
comes in as uvw jet environment with a
spherical mapping type which is good for
HDR dome images but not for flat
backdrops like this JPEG set this value
to screen and the image comes in nicely
now if you have network rendering and
able to with swarm go ahead and enable
that now as we prepare to start a final
render swarm is a way to distribute
rendering across a network of render
machines to speed up rendering but you
don't need this at all to render the
scene out of rhino in the VfB stop the
interactive render and in the asset
editor turn off interactive set your
quality to high and launch a production
render with this icon elapsed one minute
here to get to this result immediately
now we can make adjustments to this
image before saving it directly through
the VfB by clicking the show
corrections control icon expand the
exposure rollout and enable it highlight
burn controls the highlights and the
hotspots so I'll bring it down to about
0.7 expand color balance and also enable
it here I can adjust the color of my
shadows for example to cool them off a
little bit you could of course set your
render as desired
now I'll add a curve to punch up the
image a little bit like so and then I'll
collapse the corrections control and of
course to save your image simply click
the floppy disk icon and here we are a
lovely earbud that you can hear just by
looking at it thanks for joining us on

using v-ray for rhino
