welcome to this QuickStart tutorial for
v-ray for Revit in this video we'll be
taking a look at getting started with
using v-ray for Revit and getting
familiar with how to get productive
we'll start with a sample scene already
installed alongside Revit start by
opening a project inside Revit and
navigate to see Program Files
Autodesk the version of Revit you're
using samples folder and open the file
are AC basic sample project file once
the scene is open open the v-ray tab
we'll start off by rendering a view we
have click on the from a yard view to
bring that up click here to disable
shadows to speed things up a bit in
Revit now let's render a quick version
of this view to fine-tune our settings
first thing you'll notice is that the
Revit interface locks out the controls
for plugins while here in a perspective
view
so I'm going to switch back to the title
page view and you'll see the controls
are active again this is true for all
plugins in Revit and is normal behavior
for a real-time render of the yard view
select the from yard entry in the
project views to set it as the current
view and go ahead and leave the quality
set to draft for now now click on
resolution here in the v-ray tab you can
select from the preset resolutions or
enter your own or use crop region which
is similar to Revit existing
functionality let's use the 800 by 450
preset next you can toggle artificial
lights on or off by clicking this icon
we'll leave them off next we can choose
our environment light to use a v-ray son
or a dome light with dome lights for
example you can use image based lighting
which we'll cover in more detail later
in the video
and of course you can turn off
environment lighting as well by clicking
this icon will use the Sun for now with
its current Revit settings
now I'll move the window to the side of
my screen to make a little bit more
space to work with here you can set off
a rental pretty quickly click on render
with v-ray icon and here you can choose
render with v-ray RT to start a real
time rendering of the from yard view
that we selected earlier this is called
the v-ray frame buffer or VfB let's go
ahead and stop the render first off lets
replace this grass which means we use
the material browser now all materials
from Revit are already supported with
v-ray which is good as we don't need to
setup new materials necessarily although
the array materials can offer more power
and possibilities with your renders I'm
going to locate a grass material here in
the filter box and here we go it
displays in the material browser the
auto jenn means it is using a Revit
material I'm going to switch it to a
very material instead bringing up a
browser to load a material from my
folder called green grass dark vr mat
you'll find that material in the assets
you can download for this tutorial now
like Revit materials you're going to
want to set a size for width and height
and since this is a pretty big map I'll
use 10,000 by 10,000 millimeters and
I'll just randomly pick a rotation with
the slider go ahead and close the
browser now now one more thing on the
Settings icon before we get started
v-ray RT takes full advantage of CUDA
hardware rendering on nvidia graphics
cards one of which i have installed if
you have a strong NVIDIA GPU go ahead
and select the GPU CUDA option here
otherwise you can eat easily leave it at
CPU click on render v-ray with RT to
fire it up there are a few things I'd
like to change before the final
rendering let's change the location of
our view by moving the camera around
with the window to the side I can see
the rendering whilst
able to work my settings let's go back
to the from yard view go ahead and press
ze to zoom extents to make this easier
then open up the navigation wheel and
orbit the view as I do you can see how
arti updates the render pretty quickly
go ahead and set a lot of you you like
I'm going to settle here in my view
checking RT to see the render result as
I go now I'll close the wheel and
address the Sun angle next here in the
properties I'll scroll down to the
camera heading and click Edit to open
the render settings changes I make here
will affect the render in real time
click on the Sun settings button here
which will bring up the window let's
change the time from 12 p.m. to 3 p.m.
and click apply and you'll see RT update
to more afternoon light we can also
change the time of year that's pretty
handy let's click OK to get out of here
and we'll get into using in HDR next for
something a little more photo real HDR
image is of course high dynamic range
image that can give an exquisite result
in lighting and reflections I'll need to
exit my perspective view for example to
my title sheet to gain access to my
icons again click on the v-ray son icon
to access environmental light and switch
it to the dome light the arty render
updates and you can see the dome light
evenly lighting the scene with a single
color specified by the dome color swatch
will replace that with an HDR image by
clicking the use HDR image checkbox and
you'll see the VfB update immediately to
show the new environment you can browse
for any panoramic HDR or EXR image that
you have there's plenty available online
to download for free so it's easy to
find an environment that fits your needs
use the rotation value here to orient
the environment to your satisfaction
this in turn moves the Sun in the image
which will of course change the lighting
angle in the scene I'm going to settle
on
145 degrees for a pretty nice look now
I'll make my adjustments to my camera
click on the camera icon to open the
camera settings I'll increase the
exposure to brighten the image and I can
also adjust the white balance to find
the right look click on the effects
button here you can set camera effects
like depth of field with the D focus and
focus distance controls I've set my
focus distance to the back of the
building right now RT is updating the
VfB window as we go and as we adjust the
blur I'll go ahead and turn it off by
changing D focus back to zero and make
instead a bit of a vignette just here in
the corners now let's go and set our
render quality to high change the
resolution to 1280 by 720 and we'll also
switch from our T to the production
render and when we click here we go as
you can see the render starts filling in
once we get past the earlier passes we
can begin changing and fine-tuning some
adjustments without really needing to
pull the image into Photoshop and this
is while the render continues
progressively to get a cleaner and
cleaner result the longer it runs in the
VfB I'll open up the show Corrections
control and I'll be able to fine-tune
things like the exposure of the image by
turning on exposure and manipulating its
slider now let's adjust the white
balance away from being too warm and you
can play with the saturation and hue
levels with these controls as well as a
matter of fact there's a lot of control
for level and curves like you would have
in Photoshop
I'll curve the image a little bit here
and then you can check it on and off to
toggle to see the difference I'll go
ahead and leave it off and allow the
progressive render to continue cleaning
up the image for a little while longer
and because this is a progressive render
meaning it will continue to clean up the
image as you allow the render to
continue
you can click on the track mouse while
rendering icon and place the cursor
around these railings here this tells
v-ray to concentrate on that area for
cleanup before moving out to other areas
of the image if you want one part of
that image to resolve sooner than the
rest okay so at this point our image is
resolved pretty nicely go ahead and
click the stop sign icon to halt the
render when you're happy with the image
quality
now that the render is done there are a
few ways that you can save it one way is
directly from the VfB by clicking the
Save button and selecting any of these
image formats will select PNG here
another way to save out the rendered
image is to actually close the frame
buffer and the application actually
keeps a version of the file saved in the
project gallery select the view from the
yard that you rendered and it will give
you a history of all the renderings from
that view just click the icon here to
save it to disk as one of these image
formats you could also click this icon
to save it to the project by default
Revit will try to overwrite the existing
view as you can see here in the list so
just choose no and it will create a new
view under renderings as you can see
here and there it is it's now in your
project and it's available to drag it
out onto your sheet here for example all
ready to go thanks for joining us on
