This scene is fairly complex in terms of lighting. There are 11 VRay lights, all with Multiply values of less than 20 units. Only four of the VRay lights were projected directly onto the car, while the other seven were turned to face other directions to create blurred reflections and diffuse shadows. This is a very important technique when working with this type of lighting, so that the lights won't be overexposed. I also used four vertical white planes and an extra plane just slightly above them to create the reflection on the body of the car, just as if it were in a photo studio. I used one third of a smoothed sphere to create the impression of an infinite background, with 100% white color (Fig.13).
Even before rendering with custom shaders, it's important to setup and render test just the lighting of the scene, without applying any kind of shaders. This speeds up your work process and is more efficient because the yield is much lighter, and in this case the only concern is whether the lighting works as what you intended or not (Fig.14 - 15).
Rendering with VRay
Using V-Ray to render, I used settings that made an interesting combination. These parameters are not set rules but more of a study and personal preference of my own. If you want to try it out for yourself, I suggest you start off with the following parameters and then tweak them to your liking (Fig.16).
After adjusting the V-Ray parameters, I achieved the result shown in Fig.17 - 21. These all have a resolution of 3072 by 1728 pixels. For these five images I didn't use any extra render passes, such as Shadow, Ambient Occlusion, Specular, etc.
