Light

The light system used was basically an HDRI inside a V-Ray Light Dome and a V-Ray Sun. The big difference here (or perhaps the little secret) is the skylight glass and what happens inside the structure. At first, I wanted to have only a V-Ray light dome, but the result didn't look very realistic. So I decided to boost the light inside the skylight and treat the glass as if it were being hit by bounces of light that would eventually pass to the interior.

Fig.20 shows the lights and how and where they were placed. There is a V-Ray light with a skylight portal in one of the windows, but it had zero effect on the scene and was just there for testing purposes; it isn't used in the final scene. A V-Ray light with an intensity of 10,0 was set to Visible and placed inside the skylight.


I wanted the frost glass to have a glossy look and at the same time a nice refraction so that it would be possible to see the metal structure inside of the skylight. The glass was made using a V-Ray blend material, which was a glossy glass combined with a V-Ray light material. It was set to an intensity of 100, the color was RBG (57, 95, 153) and the blend amount was a gray value equal to 5 (Fig.21 – 22).




Here are the frosted glass settings (Fig.23).
