Lighting an Interior Nighttime Scene Using IES Lights - Photographic Rendering with V-Ray for SketchUp - page 101

To add an IES profile to our light, with the SketchUp Select tool active, we need to
perform the following steps:
1. Right-click on the light object.
2. From the list, select the V-Ray for Sketchup option.
3. From the flyout, select Edit light .
4. In the V-Ray light editor , click on the File browse button in the Options sec-

entitled 30.ies ).
5. Highlight the file and then click on Open .
6. Click on OK to exit the V-Ray light editor .
As easily as that we have attached real-world lighting data that includes both
intensity and distribution patterns to the V-Ray IES light object, and so we are
now ready to give it a test render. To do that, follow the next steps.
7. Make certain we are looking through the POV Shot - Main Gallery camera.
8. Next, click on the Render button up on the V-Ray toolbar.
Take a look at the following screenshot:
As you can see in the render, what we get looks pretty good, given that we are shoot-
ing for a subdued, after-hours feel to the lighting. However, it may well be that once
a number of these lights are added into the scene (along also with the up lighters
that we will be putting in place in just a little while), we could possibly end up with
more illumination in the environment than we really want. That, however, is a bridge
we will cross when we come to it.
What we need to do right now of course is replicate our light by placing a copy in
front of each of the wall-mounted frames that need illuminating. Unfortunately, even
though turning our light into a component would be the ideal way to proceed at this
point, this option hasn't worked very well since before V-Ray Version 1.49. with cer-
