Blender 2.8 Eevee Tutorial – Creating Cool Ambient Scenes with Volumetric Lighting


welcome on back to the smooth stylings
of cool ambient scenes. hey guys, welcome back to tutsbykai. I’m Kai and today we are back in blender 2.8 once again taking a look at how to create some cool ambient
kind of lighting and scene and this really really ah really neat way. so I
have three lights set up here. I have two area lights. I have one coming down from
the top hand side, the top right hand side, which is on ten energy and there’s
this blue color right here this blue color and then I have one coming from
the left back which is on also one ten energy and is that pink color right
there pinkish kind of red color and then from the top I have a little bit of
purple which is twenty energy and is this color so we have three lights of a
three point light set up here and I have a my camera zoomed in quite a bit. the
focal distance is it’s quite long here. two hundred and ninety two millimeters.
we’re gonna go ahead and split our window into two to go over to the shader
editor also known as the node editor. we can go and open it up right here. ah shader and we’re gonna go ahead and create a new material for our head that I also
got off of 3d scans.com. I love that website. they got a lot of great
stuff on there. go check it out. the link will be down in the description as
always. I’m gonna go ahead and turn my overlays off so I can see just a scene. I
want to see I’m gonna go ahead and also go to the world tab here hit use nodes
and change the color of our backgrounds to solid black now we have a bit more
ambient I’ve seen already with our head we’re gonna go ahead and create a new
object we’re gonna create this new object it’s new material sorry we’ll
call this material head mat. yeah sure. alright we’re gonna hit N to get rid of that
tab right there on the side and what we gotta do now is pretty much for the
head itself is gonna be pretty simple. we’re just gonna add a little bit of
metallic just a little bit of metallic and turn on that roughness a little
bit and that should be good the way it is actually. so that’s fine the way it is
and then the rest of this is pretty much nice post-processing stuff. so what
I’m gonna do is we’re gonna head over to the– we’re gonna change from the object
shader editor to the world shader editor here so now we can control all the world
nodes and stuff like that. we’re gonna go ahead and check a couple of things over here on the right-hand side panel and the render tab
here. we’re gonna check screen space reflections. you can see how– what that
does right there, which looks really pretty nice and we’re also gonna check
volumetric and we’re also gonna check the ambient. yeah other than that
we’re good. so for the material I do want to do one more thing so let’s go back to
the material and do the ambient occlusion now. I forgot about that. we’ll
go ahead and hit shift A and hit search and then we’ll do– we’ll type
ambient and this grab that ambient occlusion shader. plop that right there
and plug the AO into the base color and now you can see the difference. well if I
turn, now you can see a little bit easier. there’s a little bit of a difference
there and you’ll be able to tell a lot more later on. we can go ahead and
downsize this. change the distance around, make it a bit more easy to see, just
things like that. and you can see there you go yeah. that’s what I’m looking for right there alright. so we have that down. I’m
gonna go back to the world tab now. actually we can change the distances on
here too but but I like doing it over here. it’s much easier. so we just put
that back on whatever it was. I think it was one. wasn’t it? yeah one. all right so
we go back to the world tab here and what we’ll do is we’ll make sure we have
one thing. really need one thing. shift A and we’re gonna type in volume and grab
the volume scatter node and place that right beneath the background node and
plug this into the volume. now you can see things got kind of grey. the reason for
this is because we got some stuff to do still. so we’re gonna go ahead and as you
can see, if I go out of my camera I can’t see anything, so I have to go ahead and
zoom into our head to be able to see anything at all. so now what I
have to do is– we can’t see anything in our camera– either change the density
down to point 2 and we’re getting something like this… that’s a little,
that’s a little dark still. so we’ll go ahead and go point one? two? it looks like
point one looks pretty good. we’ll use point 1 and I’m gonna go ahead
and change go down to my film here and, not film sorry, color management and
we’ll change the view transform from filmic to film and now this looks pretty
cool right. it looks pretty cool. it looks pretty cool you know. I think we might be–
oh no we can’t– we’ll go ahead and do one anyway we don’t really need
to mess with this too much. we can go ahead and just place it–
we’re around the 0.4 maybe 0.2 yeah. 0.2 looks good I guess. we’ll leave
it on 0.2. and then under the volumetric section we don’t have to mess
with a lot here. we can just play around a couple these things. you can see
you can see pretty much, we don’t really need to do anything with these. we can
put this back on 0.5. you can see how this is coming together pretty
nicely so far. what I want to do now is– we turn that screen space
reflections back on there. we could add a little bit of bloom there so we’ll go
ahead and turn bloom on as well and we’ll turn the threshold down a little
bit and the radius up just a little bit. We can also change the color to
like a little bit of a lightish blue… something like that. just so it has a
little bit of color to it. yeah. looks good. all right.
and then the intensity can go up a little bit. just a little bit. there we go.
so that’s pretty good the way it is right there and I think that might let
me change just a little less of a blue. something like maybe– I would do maybe– I do wanna stick with just white. maybe I do
because maybe looks like a little bit of a highlight there. alright that looks
good so that’s pretty much it. what I’m gonna do now is it’s still kind of dark
so what I think we can do is– we can go ahead and we can do a couple of
different things. we can either go and add in or we can change our camera. you
can go to our camera tab and then zoom our camera in by double tapping Z G and
then double tapping Z and then pushing it in a little bit and then changing our focal
length outwards to kind of make it a little bit brighter there. so you have a
little bit more color which is nice. we could also– this is a more realistic
render– the head looking you know not all cartoony but if we go to our object
tab and turn the metallic all the way up and then turn the roughness all the way
down you can see how we get a really nice cartoon like effect which is really pretty cool but I’m not going for that today. so we’re gonna go
ahead and turn the metallic back down and the roughness back up. not too much
though because you see we start to lose these edges here that I want. I
want to get the edge of his jaw and we have that right there and then we can
turn up a little bit. there we go. so I think that looks pretty cool and
we’ve used quite a bit of these post-processing settings over here on
the side. you could of course always add some depth of field and some other things here and there but this is a really pretty easy and a nice effect that you’re getting here with little processing
time. I mean we can zoom out of this thing you see. if i zoom in closer
then the lights get bright. you know things get blown out because of the
volumetric lighting. but if we stay back here where we’re supposed to be and you can see how cool this looks. it looks like stadium lights. really it does. but
that’s it. it’s really cool. really fun to do. it just looks so great
and so nice. we can change these colors around obviously and we can get some nice stuff. maybe we want them to be in more green atmosphere. maybe we’ll do something like a green and a yellow, you know. and then the point light up on top,
we’ll do like white maybe. yeah sure yeah. look at that.
so it’s not ambient as the blue and the pink and the purple but there you go.
so that is the cool ambient scene right there. I did this off-camera
and I thought I’d do a little tutorial on it cuz it’s pretty cool looking. I hope
you guys enjoyed it. hope you learned something new about mixing all these
different things together and the– of course the volumetric lighting is the
big thing here… without that, this is what it looks like. yeah so if I turn the
bloom off you can see really the difference that it makes. look at that.
yeah that’s insane. so we have this nice gradient from the side, from side to side
here and then of course it makes the head look not as harsh and much much
better than it did previously. so that is going to be it for today’s tutorial. hope
you guys enjoyed it. I’ll see you guys in the next tutorial, but until then… buh bye!
