Hey, what is up, nation?
In this session we're gonna be answering a question from
Tavian, who asks "How to do a only line showing render? I've been trying out
Sketchup for a few months now and people have done some renders that has only
black lines on white background. Can you guys please help me?". We're gonna be
jumping into that after the intro!
Alright, so I found this really cool retro racer model on the 3D warehouse. It
seems like this is often a sci-fi kind of thing, or a schematic type thing that
people are looking for. There's two different ways that we're gonna approach
this. The first is straight from Sketchup. How do you get your, sort of
schematic drawing? Directly out of Sketchup and the key with that, is
really...lot of times you just wanted to be monochrome. And all of this is really
basically in the style. So you want to go to a window -> default tray, and then
this will say "show tray". If you don't have that selected. And we're gonna be
working with the Styles bar. So here to make sure that's checked as well.
Now I...over here you can see we have a bunch of these little things. In style,
though, this main part we have the faces selected. We have this texture, the thing
is called...let's it go. Let's mouse over and wait a second.
Display shaded using textures. So that's one way to show things. This next one...
it's this one. A display shading you using all same. So that's basically like
a monochromatic version. Now what happens when you do this is that you can see
that this model has some faces that aren't. Then it looks like there's two
colors unless there's like a gray and a white. Now what happens in Sketchup is
that because everything is face based, sometimes the wrong face is showing
outward. And then something we need to correct to make sure that our model is
looking nice. So I'm just going to go all the way into this and then right-click
and do reverse faces. Let's see we get that white face,
purrs faces. Now this one's a little bit tricky. Because it's like partially
selected. So, when you sucked a bunch of these faces on right-click you can also
do, and do orient faces. And they'll try to like figure it out. Sometimes it works,
sometimes it doesn't. In this particular case it's not really
working that well. If we select "hidden geometry" and select everything...we don't
even get that option. So what you may have to do like in this instance, is
actually come in and manually reverse the faces. So that's what we're going to
do really quick. I'm just gonna go through all of these and make it so that
all of these faces are white, and we will come back after I am finished that. And
get to the next step.
All right. So I think we got most of the phases oriented correctly. And then we're
just gonna select our camera view. So we're just gonna save this, hit plus on
the scenes, so that we save that. We see we have a new scene here. Just so that
we're saving our perspective, in case anything happens. As always, you want to
make sure that you save your file early, and often. So we have this. And then let's
just do that at a good measure, I'll call this "Retro bike". It's like a sci-fi
retro. It'll take probably 25 minutes to say. So this is basically what we
have. Now the trick here is really in the line work. So what I'm gonna do is
go to this little guy on the edge. It's called "Model settings". Gonna turn off
hidden geometry so we get sort of like a uniform look.
Turn off the model axes section cut section fill guides, just turn all that
stuff off. And then update this style. And then come here. The trick here is...it's
just making sure...basically like getting what you want. And that's edges, back
edges and profiles are pretty much what you want. You may want some of these
other things and feel free to mess around with those. Profiles just sort of
like thicken some things up. Edges are all of your your major edges. But if you
want sort of that just like white look, that would be this guy. And then edges is
this. And then profiles you can change. This is like basically the depth. So if
you want like a thicker sort of heavy-handed line, you want to choose
that, and then back edges. That's basically like the ghosting of stuff. It
makes it a little cluttered. So I'm not really a particular fan of that. But
unless you can see like the profiles give those a nice like sort of contours
that you don't get otherwise. So that gives you this, and then you can go to
file -> export -> 2D graphic, and if this is what you want,
then you can just do that. We're going to sort of take this to the next level. So
I'm going to export this as retrobike.png, but I'm gonna use a renderer to
render this. And then Photoshop it. So I'm gonna use v-ray for this. I'm just gonna
do render interactive. This isn't gonna be like crazy, just we'll leave the Sun
the way it is. I think that's what I'm gonna do. I just hit this and hope that
v-ray starts. Okay, there we go. So in v-ray by default it's gonna render those
materials. Because this is just showing the styles. So we need to do in reach
v-ray is choose your settings and then go to material override, and then just
check that, and then re-render. So now we have that sort of like clay model
looking thing. And you may want to put in a ground plane. So for this, since I
already saved that, that's fine. Put in a ground plane right there, just to get
that sort of look. And I want to make sure that I'm saving. I'm not moving
around the model. Because we're gonna use that line work that we use. And if I move,
then this isn't gonna work. So this looks pretty cool. I'm just gonna copy this to
the clipboard, open Photoshop, go to open and choose my retro bike file. That's
this guy. So I have that. Gonna open a new tab. And then hit control+V for paste.
Actually you know, let's just open any file. We'll do this the reverse way. Paste,
so I'm just pasting that in. And it looks like it's a little bit off-center. Let's
just crop it a little bit. Just give a little bit more. It looks
pretty good. Now we're gonna choose this retro bike file. I'm gonna hit ctrl+A to
copy all. I wanna make sure I have that layer selected first. ctrl+C to copy, ctrl+V
to paste. And I'm gonna change the blending option on that layer to
multiply. And then I'm just gonna eyeball it. Hit ctrl+T to transform. Make sure
that I'm holding shift when I scale this, so that it scales uniformly with the
original. And then you just sort of want to eyeball this. So you can use the arrow
keys to push or pull things up or down. And I'm using the edges around, to kind
of get what I'm looking for. You just want to line things up. It's best you can.
This looks...it may need a little bit it... doesn't need to be like a hundred
percent accurate. Just mostly accurate. That looks pretty good. So you have that
sort of look. What I like to do with things like this is just turn the
opacity down a little bit. So let's go like 50 percent. And I think you get all
that line work in there still, but it has like this schematic look. And then you
can save this and upload it to your file. So hopefully this helped. If you like
