Vray Lights Tutorial: Basic Vray Lighting Setup for Arch Viz Interior Rendering 3ds Max

Alright, I’ve had some requests to do
some interior stuff, so, what I’m going to do is apply the stuff we’ve already
learned for exterior; the modeling and all that kind of all those kind of
things the materials and just show you how to apply it to an interior. It’s a
little different for interior the unique part that’s especially for interior is
the lighting that’s going to be a little different so what I’ve done is I’ve set
up a basic box here just out of polygons and I put a camera inside I’m using
v-ray again and if you’re a physical camera and I’ve got these windows on the
side so this is just a very basic room I’ll show you how to do a basic lighting
setup for an interior scene like this first thing you have to consider is kind
of well first of all let’s put a generic material on this so we can light it with
just an all grey material and we’ll figure out the lighting before we really
put any colors into the scene and that’s one way to do it it’s not the only way
to do it you don’t have to do it that way but in for the sake of time I’m
going to do it this way and not spend all the time to put colors and materials
everywhere because this is just for demonstration purposes so make sure you
take your physical camera and you set your vertical tilt to be correct minds
not cooperating for me it is set properly but it’s not displaying that’s
okay but we need to make sure that the vertical lines are straight up and down
like I showed you in the exterior series this polygon here I’ve detached
I’m going to make one material for that and it’s going to be a glass and we’ll
make it similar to we’ve the way we’ve made other glass set it to solid black
I’m going to be going through this pretty quick because we’ve gone over a
lot of this before you can see I have updated my version of
v-ray but basically everything is the same it’s just moved a little bit around
so for now reflections will be Vaughn for that glass turn up the reflection a
little higher for refract what we’re going to do here is make it pretty
refractive and because this is a single plane we’re
going to kind of take off all the index of refraction just set it to one point
zero one kind of the magic number so nothing’s really distorting as it goes
through that glass because it’s a single plane the distortion doesn’t work like
it really would if this was a double plane if I put a shell on that polygon
which I can do let’s do it that way it’s a nicer way to do it
but just keep this in mind put a shell on it of let’s say 0.5 inches then you
would just leave that refraction on one point-six will work leave that index of
refraction number now the important thing here is going to be effect shadows
that makes it so the direct light can come straight through that window let’s
apply this to the polygon call it glass okay so now we have a basic gray
material on everything and then this class so I’ll show you how to get the
direct light coming through there remember effect shadows needs to be on
for that direct light to go through that glass let’s do one other thing units
move this glass into the mullions a little bit like that that’s great okay
v-ray son go to the lighting tab drop down to v-ray go to v-ray son and just
click where you want the son to be and drag where you want it to point would
you like to automatically add a various guy environment map yes let’s go to the
right view and raise that son up a little bit so that will be coming in at
that angle there now one thing you need to keep in mind
when doing this is that the v-ray camera and the v-ray Sun is all set up for
physical accuracy so the Sun is set to be as bright as the real world Sun so in
other words it’s very very bright so in order to get the right exposure you’d
have to turn on exposure in your camera and turn your shutter speed up like with
a real camera so that it doesn’t get too bright but what I like to do and this is
this is another way to do it’s kind of a workaround you can just set this to
about 0.05 the intensity multiplier of the Sun then you can just turn off the
factor exposure factor and turn off the VIN yelling as well that way the Sun is
now dim enough that it’s not totally blowing out your scene and the you’re
just using default exposure for the camera now all that really does is take
one more factor out of your lighting equation because it’s kind of a moving
target if you’re trying to adjust both of these at the same time and trying to
get the exposure just right so I just take one out of the equation and only
adjust the Sun now that’s one way to do it
you can also just leave the exposure on set all your lights how you think they
should be and then just adjust your exposure up and down until it looks like
the right exposure so we’ve got our Sun let’s do a basic rendering now okay one
other thing I should mention before I render this is what it was coming out
like but obviously there’s a big purple plane outside I don’t remember if I
showed you before but that’s a v-ray plane so it’s that and if you go to
create object v-ray beer a plane you can create that and it’s just an infinite
plane basically so I’ve said it doesn’t matter where you set it in your scene in
the X and y-axis but in this is in the z-axis the Z world axis it does matter
so I’ve set it just below the floor the only thing I forgot to do is assign this
grey material to it and that plane extends infinitely
upwards so let’s try rendering again we’re looking pretty good here we as you
can see effect shadows is working the lights coming right through the windows
and of course with the global illumination on the light is hitting the
floor bouncing up through the room and lighting the entire room super simple
setup but it gives you a very nice effect with a nice soft lighting in the
whole room just from putting that direct light in so if you wanted a scene where
only direct light is coming in you could put these big windows fill up the whole
room with it and you’re pretty much done lighting your interior scene now all you
have to do is fill it with nice furniture but I am going to show you a
couple other things in case you want different lighting situations so let’s
let this render okay that’s pretty clean right there you can see the nice light
the nice crisp light coming through and it gets a little fuzzier over here as it
gets further away from the source of the shadow casting of course you can always
take your Sun and you can increase the size of it
say like six and it’ll crease the size of that disc and what that does is make
your shadow as much softer like maybe an overcast day maybe let’s exaggerate it a
lot just to see what it’ll do size multiplier see what that looks like okay
now you can see that the shadows are much softer they’re not very clean
because my settings are low but you get the point you get these very nice big
soft shadows if you make that Sun that light source really big now that’s
something you need to keep in mind when you’re lighting with v-ray lights on the
interior as well let me show you that actually before I get to that let’s show
you one other technique which is to put a big v-ray plain light again v-ray
lights create v-ray no lighting tab here a light
there’s a couple different kinds of lights here plain dome spare mesh disc
okay we are going to use the plane it’s the
one I use probably most commonly and the names are self-explanatory but mesh is
any object that you want to make self eliminated now I made a very plain about
the size of that window it’s a plain light let’s place it just outside the
window and we’re going to pump it through that glass to make it so that
there’s a nice diffused light coming in from the windows like they’re a giant
light source you don’t want to play this up too much in fact two might be the
multiplier we want and I remember when you have a large light source like this
the intensity increases with the size so a really big light like this set at 2 is
actually a lot of light coming out it was a tiny little light set at 30 it
would still be probably less than this ok so the size matters as far as
intensity so if we set it at 2 and if you set it to like the color of the sky
it’ll basically be pumping environment light into that room this is a technique
that people use a lot to light their scenes with a natural-looking lighting
so let me render that for you now one important thing I forgot to tell you is
to make that light invisible because as you can see that the direct light was
not coming through that light it was hitting it and you’re actually seeing
the solid light right there so make sure it’s invisible you can actually turn off
effect reflections because you don’t want to see that in like a mirror or
something because we want it to be hidden but it can still affect the
diffuse that means it’s lighting the room still and the specular that means
it’s putting highlights on objects in the room so let’s try that again okay you don’t really see it a lot
because it’s not overpowering this direct light very much at all but it is
a subtle light coming in you can see it hitting the wall right there is bluish
tint up here where we put in that wall you might want to turn that up you might
want to not have it at all because this room is small and that direct light is
really filling up the room with light a lot so you might not need it there if
you had a smaller window you definitely want to pump some more light and using a
beer a plane outside so that is another technique now a little bit about your
interior lights there’s basically really two different options and that’s all you
need to know essentially there’s the regular v-ray light and there’s a plane
a dome is for environment lights so you wouldn’t use that for an interior a
sphere is just a ball that puts life and light in all directions a mesh is any
object that you assign it to will become a light and the disk light is is like a
well it’s exactly what it says it’s a disc shaped light okay
disc is a newer feature in the newer versions of viewer you may or may not
have it but because it’s new I haven’t really worked it into my workflow yet
but I’ve always used just planes for lights on the ceiling but really disc
will probably be what I use more in the future moving forward because usually
I’m putting can lights in the ceiling and they’re shaped like discs not planes
but let me show you how to do with planes and the same basically all the
same things will apply to a disc as well so plane light if you have like a six
inch can up here put your half width and your half length at about three inches
that’s exactly what it says it is that’s half the width and half the length of
that light so if it’s half is three then the full six so that’s about the size of
a can light okay make sure and put that up here now you’d actually model a can
light too and then you’d probably put this right in front of it
so that the model of the candlelight is probably got a self illuminated bulb on
it but that’s not what’s actually lagging you’re seen you put a light in
front of it to actually like the scene that’s the best way to do that and then
this would be somewhere around sometimes these get high like a hundred maybe and
you’d put them with probably a warmer light because most light bulbs are
warmer in people’s houses you have somewhere like around in here right
something like that that’s like a soft white light bulb okay and those will be
invisible too because you don’t want to see that plane sitting in front of your
modeled can light these can affect well no you don’t want those to affect
reflections either what that means is if you have a mirror or something in your
room and you see the can light in your mirror you’ll see that light sitting in
front of it so you don’t want that but it will still make highlights on objects
in your room because effect specular is on okay now the other thing that you
subdivisions is kind of the quality of light coming off of it you don’t usually
have to mess with the default the other thing that you might want to mess with
is the directional so zero means that it’s going straight out to the sides and
down from this plane okay so it’s going like in an arc like that around the
light if you put directional to one that means it’s coming only in the direction
of the normal in that arrow coming off the light so it’s going straight down
and it maintains that profile all the way down to the ground so you’ll see a
light it’s like a spotlight coming right down to the ground you’ll see a light in
the shape of this plane being cast right onto the ground so that’s not what you
want but you might want for a can light they are directional somewhat so you
might set this to many point two or point three
let’s move it over by the wall so we can see how it’s cast and I’ll just do a
quick render of it for you let’s make sure it’s in a good place in our room
let’s put it like over here and render okay here you can see that that plain
light casting light down the wall you see it doesn’t fan out too far because I
did put some direction on it obviously it’s a little too close to the wall but
the intensity looks pretty good I think let’s change that real quickly to a disc
you’ll see that it’ll look basically the same but let’s make it a little more
directional point six and I’ll show you how it looks
let’s move it away from the wall a bit and let’s put a few more in here hold
down shift instance it twice and then we’ll instance it three times across the
room like that now I’ve got a bunch of light in there and these are all
instance so if you turn down one which because we’ve got so many in here now
we’ll probably want to turn them down so 70 that’ll turn down all of them let’s let’s turn this up a little bit let’s
turn our Sun back to the regular size okay and we’ll see how that looks
really quick all right well there you have it that’s pretty much a basic setup
for an interior lighting you can see that the brightest spot of course is
where the Sun is hitting as it should be but you have a nice balance of
artificial light in here too it’s a little bit being cast on the walls and
over here you can see there’s a lot of light from those canned lights we’ve put
in there’s very subtle light coming from these windows from that big plane so
really it’s a nice bright kind of a little bit maybe overexposed but once
you start putting color in there I think it’s all going to look good so if you
want to know how to fill this up go check out my 3ds max furniture class and
you’ll see how to model knickknacks objects and furniture to put inside this
scene that should be very helpful to you and the only other thing I want to
mention is that the other option here for lighting
for these cans you could also use a v-ray IES light which is right here
let’s move editor talk to you to put that in where’s Matt ah so we want okay there you go
so that just looks like a sphere with a target on it which is all fine but if
you don’t know what IES lights are then they’re just a file that you can assign
to this light which is put out by the manufacturer of actual lights and it
gives you the exact pattern that that light will light will be cast in so all
you have to do is assign that file here so if you search the internet for dot
IES files you will find some and usually they’ll have a preview with them of how
that light is going to cast so you know each bulb casts in its own particular
pattern and that is provided by the manufacturers of lights oftentimes with
an IES file so you can assign it here and then you just kind of adjust it like
you would any other light with the intensity and here you adjust it with
color and power down here so the settings look a little different but the
idea is all the same and that can give you a more accurate look to your lights
and how they’re casting on the wall they’re oftentimes not necessary but if
you really want to showcase a nice scallop on your wall of light then you
could use IES lights and if you need to be particularly accurate for some reason
you can get the information from the manufacturer and plug it right into
these lights so that is the other option the only other thing is like a sphere
light so if you had a big pendant light hanging down in the middle of this room
or a chandelier or something you can just put a sphere light in the middle of
the room like that and all that is is just like the plain same settings as the
plane except it’s casting in all directions so that’s basically all there
is it is to veera lights and this is the very basics of how you would set up a
v-ray interior so again if you want to know how to finish something like this
off with furniture materials just check out my other courses
particularly the furniture master class because that’s all about making the high
poly objects that would go in seen like this to really make it look sharp so
thanks for checking this one out and we’ll talk to you soon

  1. Hi, in my design I have a large window and also used a Hdr map for outside, but in my render can't see the Hdr map, and when I render without the window glass can see the hdr map. so can you tell me what happened. Thanks
