for this lesson we'll demonstrate how
and very next for Sketchup you can
render materials from the VR scans
library on GPU which consists of over a
thousand photorealistic scant materials
each VR scan is generated by capturing a
real-life sample from thousands of
different angles which is why they
appear so realistic
now the VR scan library works on both
CPU and GPU so you can harness the GPU
to render super realistic images at
blazing fast speeds to begin let's take
a look at our scene here by first
hitting the interactive render button
you'll see that right now we have a
chair with the generic v-ray material
applied to it let's see how we can make
the chair look a bit more interesting if
we use severe scan materials instead
I'll stop the render and then let's
proceed to create our VR scan materials
keep in mind that the VR scans material
library is accessible only to vary scans
licence holders in the asset manager
right click on the materials tab and
then holding the ctrl key or command key
for mac we can click to create three VR
scan materials next I'm going to right
click on the first one and rename it to
zero one wood now let's load in the VR
scan materials we want to use by
clicking on the file folder icon in the
parameters for this material I'm going
to load in the oak gloss VR scan file
from the asset folder now let's follow
the same steps for the other two
materials I'll rename the second one
zero to leather and load in the leather
black VR scan
and I'll rename the third 103 aluminum
and import the aluminum gloss brushed VR
scan from the asset folder now let's
switch to the render camera zero two for
a closer look or feel free to choose a
point of view to your liking then start
the interactive render alright let's
start with the chair legs material first
if we right click on the material and
choose select in scene will select the
chair legs now let's right-click on the
oh three aluminum of your scan material
and click apply to selection right away
we'll see the interactive render updates
to display the material on the legs of
the chair however we'll need to make a
quick adjustment to get the appropriate
size as a result of Xavier scans are
created they represent a real-life
sample size which we can confirm if we
drop down the information tab and check
the sample or physical size to get the
correct size in our render we simply
need to input this information into the
materials tray rollout for the correct
mapping in this case we can just input
0.02 meters okay
now let's repeat this process for the
0-2 leather material this time by
replacing the chair cushion material in
the scene with the 0-2 leather material
once more let's set the material to the
correct physical size which you'll see
is not uniform for this material so
we'll need to click the chain icon and
input the separate dimensions for the
width and height now that we've got the
correct size you'll see that the leather
in our renders is black and looks nice
but what if we want to change the color
with VR scans you'll have a few
straightforward ways to do that
depending on your needs let's head over
to the appearance rollout of the VR scan
material where we'll find a section
called paint if we toggle it on we can
tweak the color of the material to our
liking without losing the texture or
changing the reflection color let's try
a reddish brown color
note that the paint option typically
works best when using a similar value in
saturation to the original color if you
want to tint the overall appearance of
the material you can use the filter
option above which affects not only the
diffuse but also other aspects of the
material including the color of the
reflections
okay let's toggle off the paint color
and move on to the chair body once again
I'll right-click on its material to
select the chair body object and now
let's apply the zero-one wood for your
skin material once again let's set the
correct texture placement like we did
for the other materials
now as you can see the wood material has
a glossy finish this is called a clear
coat and it simulates varnish we can
easily control this effect from the
clear coat rollout here in our wood
material right now you'll see the IOR is
set to one point four three seven this
controls the strength of the reflections
for example visible here where the chair
legs are reflecting in the wood we can
weaken the effect by lowering the IOR
value or completely remove it by setting
the IOR to 1 in this case though I
prefer the varnish on the wood and would
like to make the coat more prominent so
I'll increase it to 1.6 feel free to
adjust this parameter to your liking
alright now that we've applied all of
our VR scan materials let's give this
just a moment to render out a nice image
now you've seen how to get started with
VR scans and get highly realistic
material super quickly all while using
the speed of GPU rendering in v-ray next
