Hello again, and here we are with part three of our Render Talks series, which focuses
on the capabilities of NX render and have this can be applied to the Marine Industry.
In case you've missed the series so far, I'll have part one and two on the screen
Now alongside the blog series, which covers the same topics
If you prefer reading. Once again, Gavin McCambridge will be joining
us to provide industry knowledge within this part, looking at lighting
and customizing your environment.
The section is a big one.
So we're splitting into two parts for you.
Okay.
So Gavin, looking at the overall model and scene, someone who isn't an expert,
this one looks quite tricky to set up.
Would I be right in thinking that?
Yeah, th this one is a lot different because normally these kinds of
scenes, or a lot of normal renders are consumer products or something
like that is in a studio environment.
Even, you know, vehicles can be done in a studio type where, for
something like a yacht, we'd want that on the ocean, we'd want that
looking ike that.
So in this case, we, we actually, uh, looked at how we want to display it.
And a lot of that was researching and looking at nice pictures
of yachts and in ocean.
So, um, yeah, part of it was actually researching, finding out
how we want it to look and then coming up with the techniques that
we needed to actually create that as an environment for rendering.
Okay.
So you mentioned setting up a custom environment.
How difficult was that to do?
Um, NX allows you to, um, basically plug in your own HDR textures, which
are those we're using for lighting.
Uh, we can also use them for the environment as well.
So when we say environment, we're saying about what you see behind the
model and around the model, this is, this scene itself is a little bit
different than something that I know we're going to talk about later is we
actually created the C input scene into it for this, but then the other side of
it was actually having an environment
Um, that looked like water.
And in this case, we actually created one, um, and create a HDR of our own
with the sea underneath and the sky above so that we could get the lighting.
Correct for the scene.
Okay.
You've made something really impressive sound fairly easy.
So let's talk about the yacht itself.
Um, I seen the stages similar to the one that we've covered in materials
in terms of ensuring the lighting reflects the high end luxury,
So how'd you do that?
Exactly.
Which we're doing if we're doing the interior, the exterior.
So if we take the exterior, for instance, You know how how's the best thing.
How's the best way to display a product?
You know what looks great?
What, what looks good?
Obviously a nice hot, shiny, uh, sunny day.
Sorry, not shiny day.
Um, looks the best.
Um, And it's kind of like that, that's the first point.
Okay.
That starts the type of lighting we want.
And then we looked at how the lighting is going to, um, show the boat.
What I'm looking for at that point is, um, I'm looking for, um, highlights
as well as, um, sort of shadow on on the boats, give it a real effect.
It actually looks 3d.
It's not just a flat image.
And if you don't have enough of the different types of areas, so
brighter areas and darker areas, Often your image will look flat.
So that, that the key to part of this is choosing your camera angle as well as
the lighting and adjusting the lighting.
So hitting the boat certain way to give you that real sense of, you
know, the object and how it is in reality.
Yeah, exactly.
And I mean, to me, I think it is perfect, but that leads me onto the
next question of obviously we're going to talk about more of the environment
and the ocean in the next part.
But I want to ask here just about the interior and exterior
renders and how you set up the lighting for these different types of shots.
So, uh, part of the engagement, the reason we have these, these images
that we've done is, uh, we wanted to share the, the cayenne, um, what was
actually possible with NX render.
Um, one of the, one of the main features that, that we really wanted to highlight
was the fact that these shots are actually all the shots contained for this whole
project are done with the same lighting set up for the interior and the exterior.
So we don't actually change anything.
In viz, you can often have completely different sets of lighting for
an exterior shot to an interior.
And what we're looking at interior, as you know, you're often having to
brighten up lights and stuff to make it look to bounce, light around
and make it like a nice and inviting in a bright space.
What we've done here is so we've lit the exterior with the HDR.
And then what we've done in the interior is we've actually used the
model lights from the yacht itself and applied and emissive material there.
So it's an, a material that gives off light and then we've used that and
we've controlled the power of those, the emissiveness of that to actually
give us a lit effect inside of the.
Uh, sorry, yacht, not building, but that's how we're controlling that and
how that's, how we're lighting it.
And it gives a because we're using the actual fittings of the light, we're
actually getting a more realistic kind of feel to how it would be.
So we're getting washers on walls where we would expect them to be
sorry, when I'm saying washes.
I mean, how the light site kind of washes over the wall, um,
and those kinds of effects.
That's brilliant.
And the skill and technique going into the two scenes is so apparent.
It makes the whole thing just seems so real.
So let's say someone like me is listening to this and wants to try it.
How difficult would this be?
So, um, there are anyone starting out in rendering.
I would actually first start with.
Just open up, um, NX render and change the environments, this system
environments that come shipped with NX and they'll show you different type
techniques and how things are lit.
What the next thing you could do at that point is rather than going
the, the sort of route that we took, which was to completely craft
and customize a Marine environment would actually be to, to start.
Um, there are, um, HDR's available on, on certain websites that you
can go and download them from.
I would go there, a couple of those and put it into NX.
Actual sort of menu system that NX has the UI for it's quite simple.
You just go into the system scene set up and then specify the HDR you want to use.
You've got, and then got options to rotate the HDR to whichever
sort of degree you want.
And then going into a little bit more where you can set the height of the
ground levels and stuff like that.
This is all easily done within NX and it's all quite straightforward.
That would be the first part.
Just put your own HDR and try it.
And then towards the interior scene.
So this is, this requires a little bit more because what
you're looking at on this is how it's going to be lit so generally.
It's been lit from the outside.
We've got glass, we've got windows, so were getting light in there.
But then the other thing too, is I want to add custom lights in there, and generally
like for something like this, which is a yacht it's, it's very luxurious.
And again, this is a field as we've discussed before
in the materials section is.
I'm looking at the lighting and how, how the lighting is going to work.
So again, it's, it's literally going to the palette of materials.
Uh, find emissive ones.
Uh, I think they're under lights and then apply them and then go into
that material and start editing it.
And as we talked about from the material one, you can have these, two
different sets of options for materials.
There's a basic editing and an advanced editing.
So it's only what you feel comfortable with.
And do you have access to what you need in that?
Um, you know,
Okay, well, that's great, Gavin.
Um, I think hopefully that gives you guys at home and myself, if you have,
if he wants to get started, but to hear that it's so accessible and easy, and
hopefully with what we're providing with the blogs and these render talks, they're
good guidance for you guys to get started.
Um, so like I said, we'll be discussing, customizing the environment, so make
sure you stay tuned for that one.
Thanks as always Gavin.
And we look forward to having you guys on the next one.
Thank you very much for having me.
