to start let's open up the asset editor
and double check that our render
settings are set to the GPU engine and
that we're rendering on interactive mode
and turn on the denoise toggle which
enables the denoiser render element once
again
let's switch the engine over to the
Nvidia AI denoiser so that we can get
the fastest possible preview okay and
next let's make some adjustments to the
render output settings first I'll switch
on the safe frame mode this will toggle
on a visual frame overlay in the
viewport if there's a difference in
aspect ratio between the viewport and
the output image size I'm also going to
switch the aspect ratio mode to custom
in very next instead of being
permanently locked to a specific aspect
ratio you can click here on this chain
icon to unlock the image width and
height and input custom values for each
this allows us to experiment with the
image size without needing to know the
aspect ratio in advance
thanks to the combined power of GPU
rendering and the new AI denoiser the IP
our interactivity is more responsive
than ever to demonstrate just how
quickly we can work on our scene on GPU
I'll switch to a couple other
perspectives that I have set up here
just so you can get a feel for how fast
the interactive preview is in v-ray next
for example we can take a look at the
side of the house over here on the left
or we can switch to a close-up
perspective of these outdoor lawn chairs
and switch to another angle from the
right side of the house again notice how
fast the preview updates which makes it
easy to make decisions and adjustments
to our scene much more quickly okay
now let's return to our original scene
next I'm going to open up the asset
editor once more and let's go to the
lights tab and take a look at our
lighting setup here and see if we can
explore a variety of different options
in just a few clicks
first let's disable the sunlight here
then I'll enable the v-ray dome light
notice that we now some clouds appearing
in the sky thanks to the dome lights
HDRI which I had set up in advance for
this scene I'm also gonna enable the
v-ray sphere light setup here which will
turn on some lights inside the house now
let's click the dome light drop-down
arrow and select the bitmap texture
alright you'll see that we have an HDR I
loaded in here let's drop down the
texture placement menu and make some
adjustments to the horizontal rotation
let's try 90 degrees you'll see that the
HDR I texture rotates in the interactive
preview and gives us very fast feedback
making it incredibly simple to try out
different positions for the clouds and
lighting without any hassle now you've
seen just how quickly you can preview
different lighting results using the
power of via a GPU ok I'm gonna stick
with the rotation at negative 20 now
back in the settings tab let's explore
adding some volumetric effects to our
scene in very next you can now take
advantage of erased powerful environment
fog on the GPU so that you can render
incredibly realistic lighting conditions
at faster speeds than ever before let's
switch the type over to environment fog
which can give us added realism and
additional control parameters right away
you'll see that the effect is much more
pronounced creating a realistic sense of
mist in our scene I'm gonna make some
adjustments here to the height and
distance parameters just so you can get
a feel for how this effect can change
the atmosphere for example if I increase
the distance the effect becomes softer
and more subtle I can also change the
color which affects how the fog appears
when it is illuminated by light sources
let's add a light hint of blue here to
make the image a bit cooler
okay I'm liking how that looks so let's
close the flyout menu
next I'm going to click on the lens icon
here to open up the viewer a lens
effects in v-ray next the lens effects
have been redesigned to simplify the
interface and make it easier to quickly
add powerful camera lens effects like
blooming Claire to your renders simply
clicking on this checkbox will enable
the effect it's a bit subtle right now
so let's increase some of the settings
to give you a better idea of how these
work if I increase the intensity and
then the size here you can see that the
lights coming from inside the house are
starting to glow and blend outwards
beyond the edges of the walls around
them below here there are also some
other options like adjusting the number
of visible blades from the lights that
you can experiment with in your own
scenes as well you also notice that
there are modes to affect only the final
rendered image or generate a separate
render element as well you can find the
lens effects by switching over to the
glare render element all right now let's
close the lens effects
okay I'm happy with how this is turning
out so let's prepare to do a production
render I'm going to turn off the
interactive mode and then switch off the
progressive option as well so that we
can take advantage of bucket rendering
on GPU this is a new feature in v-ray
next that can improve your swarm
rendering performance by providing
better render node utilization it can
also be helpful for cutting down on
network traffic and slightly decreasing
memory usage
now that you've seen how it works to
save us some time I'm going to pull up a
completed bucket render on GPU that I
already saved from earlier
and there you go now you've seen how you
can use the power of very next GPU
render engine to get blazing fast render
previews and stunning production results
right out of the box
