Lighting an Interior Daytime Scene - Photographic Rendering with V-Ray for SketchUp - page 62

Tip
There are a couple of points to keep in mind regarding the V-Ray Rect-
angle light. Firstly, as this is a genuine area light, the larger it is, the more
light it will emit even though the intensity value may remain unchanged.
Secondly, the bigger the area light, the softer and more diffused the shad-
ows we get from it. The inverse of this is also true; a small rectangle light
will tend to give us very sharp shadows much like the defaults we get
from point light sources such as V-Ray's Omni lights and Spotlights.
Having run through its creation, we will obviously want to check that everything is
working correctly on the light. So, let's switch over to the South Facing Gallery In-
terior view by clicking on the tab, which will of course put us on the inside of the
room. (If from this vantage point it seems to you that a little more scaling on the light
object wouldn't go amiss, now would be the time to make that correction.)
One problem that we currently have is that our window is completely covered by the
light object, giving us no ability to see through to the outside environment. Indeed,
