Lighting an Interior Daytime Scene - Photographic Rendering with V-Ray for SketchUp - page 61

Although this initial positioning should work just fine, the last thing we want from our
V-Ray light objects would be to create any extra noise or render artifacts due to hav-
ing them inter-penetrating the geometry in the scene. To make certain this does not
happen in this instance, let's perform the following steps:
1. With the light still selected, click on the Over the Window Scene tab to
switch.
2. From the SketchUp toolbar, select the Move tool and then hover the mouse
cursor over the far-left or far-right corner of the light object.
3. When a snap point highlights, press and hold the left arrow key on the key-
board to constrain movement to the green axis, and then move the light away
from the window by about two foot.
As our light object was created at exactly the same size as the window opening, we
do have a little bit of scaling that we need to do in order to get proper illumination
coverage for the interior. To scale our light up, we can perform the following steps:
1. Switch back to our South Facing Gallery Exterior Scene tab.
2. With the Rectangle light still highlighted, select the scale tool from the V-Ray
toolbar.
3. In each of its four dimensions, scale the light source up enough to ensure
that it easily covers the window opening, as shown in the following screen-
