Recently, a thread on Renderosity piqued my interest on how best to light indoor scenes in Vue using radiosity. Here's what I've got so far.

Scene 1 setup
This is a very straightforward scene. Just a box subtracted from another box, then a hole punched in for a window, and added a few objects. Set all textures to plain white with no specular or reflection.
After spending a bit of time, I realized the fastest way to get what I wanted was to delete the existing sun and use a spotlight outside the window. I set the spotlight to:
Softness: 8
Spread: 25
Falloff: 20%
Power: 300
Enable volumetric lighting: checked
Intensity: 0.20
Quality Boost: None
Cast shadows in voluem: checked
Show smoke or dust in light beam: unchecked
I then set the atmosphere to 'No Atmosphere' and then used the following settings for the first scene.

Scene 1 Render
The key to the settings for this scene setup is to punch up the Gain and Sky dome lighting gain in order to create a brighter render. You can also drag the light balance more towards ambient to lighten this scene.
While this scene renders fairly fast using final mode, it doesn't render very accurately. Check out the light area under the televison and above the shelves.

Scene 2 setup
This is the exact same scene witht the exact same spotlight and no sun. This time I was attempting a higher degree of realism. First thing is to check the 'Indirect skylighting' box. This by itself, darkens the scene significantly. It removes the basic ambient from the shading equation and instead uses the bounced lighting from the spotlight.
Because it's darker, I pushed the Gain and Sky dome lighting quite a bit higher. The light intensity, light balance and ambient light sliders are moved all left. The Quality boost is pushed to the max to get rid of the 'splotchiness.' I also rendered this image using custom settings including Advanced effects quality pushed to 60%.

Scene 2 Render
This rendering was downsampled from 1024 x 768 to the size you see it here. This method takes quite a bit longer, but achieves a much higer realism. The downside to this approach is it takes longer to render and you still have the 'spotchy' artifacts, even after downsizing.
Note: There is only 1 light in both of these scenes. It is the spotlight.
