Summary
We have very importantly noted that one essential tool any serious lighter would do
well to make available to himself/herself is a set (preferably an extensive one) of IES
light profile files along with at least one IES viewer application. Certainly, the speed
up these tools can give us in terms of lighting realism makes the time and effort given
to getting them organized worthwhile.
Of course, the IES profiles by themselves would be of little use if we didn't know how
to create and then work with the V-Ray IES Light type itself. Even though it is very
similar in nature to other V-Ray light sources, we still explored a number of properties
that make the IES light type quite unique. Not least of these was the ability to attach
the aforementioned IES light profile to it, letting that control both the energy output
and distribution pattern of our light source. This all of course adds up to an increased
level of realism in our renders with very little (if any) extra cost in terms of the time it
takes to set the IES light sources up.
Having spent the past three chapters working pretty much exclusively indoors, and
having now had at least some practice working with manmade interior light sources,
it's time to move outdoors. In our next chapter, we will take a look at how we might
light a daytime exterior shot using V-Ray.
