Lighting an Interior Daytime Scene - Photographic Rendering with V-Ray for SketchUp - page 63

if we were to take a render at this point, our window opening would simply show as
solid white.
Fortunately, the V-Ray rectangle light has a very handy piece of functionality that can
be enabled from inside the V-Ray light editor. So let's perform the following steps:
1. Right-click on our rectangle light and come down to the V-Ray for Sketchup
option.
2. From the flyout, select the Edit Light option.
3. In the Options section of the V-Ray light editor window, put a check in the
Invisible option. (With this enabled, we will continue emitting light in the en-
vironment, but the light rectangle itself will now be considered by V-Ray to be
non-renderable or invisible. This is perfect for what we need.)
Note
This same feature is also available on the V-Ray Sphere and Dome light
types.
Another option that we may well want to tweak while we are in the Light Editor, one
that can help us more closely emulate the look and feel of light coming from the sky,
would be its color. As we are already working with the premise of our render taking
place on a clear sunny day, we would perhaps expect the color contribution from the
sky to be quite strong, having quite an obvious blue cast to it. To set this up, let's
perform the following steps:
1. Click on the color swatch in the Intensity section to bring up the Select Col-
or dialogue box.
2. To create a nice blue sky, we can set the HSV values to around 224 , 55 , 255 .
(This same color has already been added to the other V-Ray Rectangle lights
in the scene. However, feel free to experiment and create your own sky color
at this point, if you would like to.)
3. When done, click on OK to accept the color change.
4. And finally, click on OK to exit the light editor.
