hello and welcome to our advanced camera
techniques quick start video for v-ray
for Revit in this video we'll go over
how to use the v-ray camera in your
Revit projects for effects such as
vignettes and depth of field launch
Revit and load the project file a DV
camera RVT from the downloaded assets
from this tutorials webpage linked below
you'll be able to use this project with
Revit versions 2016 and up if you have
the chance take a look at our previous
videos on render channels and
compositing for a good foundation for
this video with the project loaded go
into the v-ray tab and change the
current view to render leave quality to
draft and set resolution to crop region
with printer set to a dpi of 150 now
feel free to choose a resolution setting
that fits your systems comfort level if
you have a strong Nvidia graphics card
you may consider going into settings and
in the RT section to switch from CPU to
GPU CUDA as I'll do here you can of
course keep your set to CPU if you wish
click render v-ray RT to start an
interactive RT render of the project
open the camera settings and click here
to expand the effects we have D focus
parameter which affects depth of field
and a control for optical Vinnie adding
grab the slider for D focus and change
the value and the arty render will
update to show the results as you make
changes let's say we want to have the
focus on this lamppost we can do that
easily using the plan view we have open
here click to expand the 3d views in the
project browser and then right click on
render and select show camera in the
plan view we can see the camera and
measure the distance from it to the
lamppost click on the annotate tab and
select detail line click to select
circle and click and drag to create a
circle from the camera to the lamppost
this way we can see the radius of the
circle which gives us the distance which
is about 7.3 meters so go ahead and
enter 7.3 meters for the focus distance
and we'll see that the lamppost is in
sharp
now draw a circle from the camera to the
front corner of the building to get a
distance of about 30 meters enter that
into the focus distance and so that
corner remains in focus no matter how we
set the default value I'll set the dafuq
is ear open six five and we'll move on
to optical vignettes by simply
increasing the value in the slider here
to see the corners begin to darken in
the VfB this could add a little
character to your render now let's set
the values back to zero and move on to
making this a nighttime shop stop the
arty rendering and close the camera
settings click the v-ray tab press
escape a couple of times to exit out of
the circle line tool click the Settings
icon select sharing and click on load
settings and load the file a DV camera
XML from the downloaded assets click
import selected turn on artificial
lights and then open the material
browser click the global materials tab
and enable both material override
checkboxes to make this render faster
and then close the window click render
with v-ray after some elapsed time you
can notice a few areas that don't seem
so great in this nighttime render like
the light from this lamppost which looks
very flat and even I'll stop the render
and use lens effects to make that look
more like what a camera would capture in
the VfB click the open lens effect
settings icon I'll enable the bloom
effect first and enable the bloom mask
intensity then enable glare effect here
and turn on glare mask intensity as well
we have a message that there is no
channel for both the bloom and glare for
it to generate those effects click to
render again and I'll elapse time to the
resulting image you'll want to allow the
render to complete without manually
stopping it because the effects apply
only when the render has completed on
its own and when it does finish you can
see a small flare at the lamppost here
more importantly the
has created a few layers now that the
lens effects can use that you can see in
the VfB I'll go back to the RGB layer
and now I can affect the settings
interactively using these sliders as you
adjust the values you'll be able to find
just the right look for creating a more
realistic camera look to the light
sources especially this foreground
lamppost thank you for joining us for
