V-Ray for SketchUp - How to use HDRI and sun settings - tutorial Video Lecture | V-RAY Tutorial (English): For Beginners to Beyond - Professional Skills

hi guide is for handle in these video
tutorial I will show you how to combine
the SEO right and the visual sound to
produce a really nice illumination and I
want to show you what kind of
elimination we are looking for so
basically I have this scene that was
made by Ron and Beckerman I use finesse
URI and the Sun system to produce this
kind of illumination you can see the
shadows from the Sun and also the really
nice contrast produced by the hgri
I have this scene here all my settings
are pretty much by default the only
difference is that I am using in the in
a sample adaptive subdivision the reason
is because I don't have I'm overriding
all the material here so I don't need
the adapted DMC because I don't have any
two fractions or fractions I don't have
too much bloating a TDR so I could use a
lot the dnc because in this case this is
faster auntie Alison meetup so I'm going
to use for now a subdivision but for my
final production render I will change
adaptive to adapt DMC okay
the idea is to use an Sui so I'm going
to replace the Sun in my GI color with
an x-ray image or sky is your image so
I'm going to select environment I'm
going to use a spherical mapping and
also I'm going to have a sky s your eye
so this is the sky the Asia right that
I'm going to use I have to brush in one
body for my BD color on one I'm sharp
for my be vehicle so the blurry one is
for the GI color and the sharp one is
for my BG color so I'm going to do the
same thing in the BG color you can
vitamin okay select the share I okay
click okay because I'm using an HDR I to
illuminate my scene I don't want to use
the physical camera I don't want that
the physical camera comes from is
partial what I still want to use the
physical camera maybe to control the
right balance or the B genetic effects
so I'm going to disable the special
control by doing that I will not use a
physical camera to control the exposure
so those option here that should speed
and the f-number and the field speed do
not affect this posture anymore okay I
want to create my first render with the
Sui so let me be sure that I have the
Sui in both sides so it's okay so let me
create my first render okay this is a
render as you notice nice I have the Sun
in the in the centre of my background
and this is what I don't want so I have
to rotate the Sun and keep your eyes in
the shadows I don't get any chart
shadows as to getting some boorish
shadow but I don't have any sharp
shadows there and the idea is to use the
Sun to get some sharp shadows okay
another very important thing is that the
that the bit color but the intensity of
the bit color of the background color is
kind of good maybe a little bit brighter
but the intensity of my illumination
should be a lot brighter so I'm going to
increase the illumination to 6
and background - - and I'm going to
rotate the Huri maybe 110 M when I move
that you're right I'm moving the area
right in counterclockwise so 100 is
going to give me the Sun in any point in
these directions from here to there okay
I'm going to do the same thing with the
Vinnie color with the background and one
very useful tips that I use is to add
and sphere in my you can see the sphere
here so I usually add a sphere to see
where are much reflection my HDR life
reflections so in this way I'm going to
add some ball a sphere and I apply a
middle anteater to that sphere to
identify the song or my reflection to
get some point of reference when I click
friend again and pause the video a
little bit this is my render you can see
the illumination is pretty nice my
background is pretty nice
the illumination also is good so I have
a lot of brighten right now but my
problem is that I don't have any sharp
shadows the idea is identify the
direction of the shadows you can see the
Sun here in this area and my shadows is
going to be somewhere in this other area
I need to control the position of the
Sun in order to produce shadows in the
same area of my s you arrive so if I
enable the Sun system
you are going to see where is your song
shadows and actually it's in the
opposite completely in the opposite side
of what I needed
cuz I need that song in this area
basically because the spirit told me
that the Sun is hitting my surface in
this area so it's going to produce
shadows in the other area so let me move
the shadows just a little bit the amount
and also I want to move the date or the
hour to get some nice result and also
you have to try to mimic the central
position of your son so you can see now
the shadows seem to be good in the right
position but how I control or how add
how I add the Sun in my scene this the
shadows is good right now so if you go
to the options in this new bill in the
1.40 a if you go to the club on switches
you could enable the default light
basically the default lights in a
Sketchup is the visual sound so if you
enable this option here you are going to
have the vibration system in your render
the problem is how you control the
intensity of the Sun because I'm not
using the physical camera i disable the
sponsor so I'm not using the physical
camera if I let the Sun with the
multiplier of one I'm going to have a
freely bright scene so the idea is to
control the song anywhere in the
environment but I have a problem here
I have the s URI in my in my background
to get some reflection so I could not
use the B color the GI color produced me
my illumination and I have the area
right there they're only two option that
I have into reflection and refraction
I'm going to enable the reflection
us to control the parameter of the Sun
but in order to throw my render I'm
going to disable the reflection because
I don't want to overwrite the be equal
but I need somewhere or I need Foom to
control my son in this way if I enable
the Sun now I have the parameter of the
Sun so I could control the intensity for
example so let me reduce the intensity
cosine now that my Sun is really bright
I used to when I don't have the physical
camera point all three is a good is a
good up some multiplier to get a similar
illumination that you have with your
default zone and with your default
physical camera so point out three is a
good point of star also I know that my
son is very low to the origin so it's
going to produce a should produce a
charm blurry shadows so I'm going to
increase the size of the Sun to produce
blurry shadow to ten if you have a lot
of noise you can increase the
subdivision to control the noise of the
shadows but for me it's okay like that
remember I don't want to override my
reflection so now I have to disable the
reflection color but I will not lose the
Sun parameter that I already set up okay
Vijay is going to stick with the with
those parameter now I have my son and my
issue are I enable let me create a
render to see what we have here we go
this is the vendor so let's render
finish but you can notice right now that
I still have having the same
illumination with Azure right let it be
brighter because I have my son but now I
have the sharp shadows that I need to
make a very powerful elimination so now
I have the very nice contrast produced
by the edge here I might reflection in
my class and also I helped a sharp
shadow that I need but in this case I
use the Sun to do
that shadows remember control the
shadows the Sun position to the shadows
options also enable the default light to
enable your Sun and use the reflection
or refraction color to control the Sun
parameter but right before the vendor
disabled this parameter to avoid
overriding your video color and apply
the Jia the Sui right on the GI color to
produce illumination and on the BG color
to get some reflections so this is to
render
I think it's look really good pretty
nice exterior illumination with NHGRI
and the Sun system so guide this is all
that I have for you today
have a nice days and we are in December
so very critical to everybody bye
