- [Instructor] As with the real time view pod,
we will want to make sure that
when rendering with Iray, we're giving the client
the best view of the product possible.
Which in turn means that we will
probably want to adjust and improve the environments
that our objects are sitting in, at some point.
To make a start, let's come to the environment menu.
And after clicking the edit option,
increase our exposure value to about 1.25,
which looks a little bright at the moment,
but because of changes that we will make again
in a moment or two,
we will be bringing this back under control.
So, not to worry.
Our product does look a little silly
just floating in the air
and I'm guessing that our end user
will most likely expect to see it
placed on a surface of some type.
So to mimic this, let's ground the object in the sea,
pun intended, but I'm making sure that the ground
toggle button is set to true.
Now sometimes when working with geometry
in Substance Designer, it may well be that
we ourselves haven't been involved in the model's creation.
And so here we have purposefully exported our product
from Houdini with a problem that you may well
come across in production in that, its pivot point
has been placed at the center of the object
rather than at the base.
This means that our product in Designer
is not actually sitting on the
ground plane that we just setup.
Even though the numbers say that,
well in fact, it should be.
A fact that is obvious given that our current
transform settings are putting it halfway
through the ground plane.
Not to worry though, as this is an
easy fix to make in Designer.
All we need to do is lower the renderable ground
along the correct axis, in this case, the Y.
And so let's set that at minus 0.56
Having a renderable ground in place
gives us nice contact shadows of course which again,
can help with the look of the finished piece.
But depending on how we have placed our
environment lights, we may now be cutting off
some of the highlights
and lighting that we setup earlier,
making the product a little darker.
Hence, the exposure change that we made earlier.
If we want to get some of that light back,
all we need to do is select each panel shape in turn,
and adjust them as we did in the previous videos.
It is perhaps worth noting here
that we do have HDRI environments that shape
with Designer for use in Iray.
And if we come to the Library tab,
and drag a couple onto the three D view,
we can see the affect they have.
I will continue to use our custom lighting
setup though, by right-clicking on the
last blend node in the panorama flow
and re-applying that to our environment.
Although we can still improve the look of things
a little more here.
And so let's add some reflections to the floor.
We do need to be careful not to pull attention
away from our product here,
and so we will want to keep things subtle.
With a value of 0.25 doing quite nicely in this case.
I will leave glossyness set to zero point five
but do feel free to spread the reflections a little more
by lowering this value if you feel
that they are still too distracting.
Now that we have improved the look of things a little,
time to consider of couple of methods that we have
available for saving our final images
out of Substance Designer.
