Materials, Lightning & Rendering
Almost all the materials used in the car's shading were procedural. I used maps only for the interior cloth and leather. In my opinion, there was no need to un-wrap the model and add some kind of dirt near the wheels or anything like that. I thought that the best presentation for my concept car would be in a clean studio render with clean reflections, where you can see the shape of the car without concerning yourself too much with reality.
The lighting consisted of one key Spot light, two side VRay lights and four big Reflection lights that didn't light the scene. I also used a chrome HDRI map in the environment slot. For rendering, as you will have already noticed, I used the V-Ray rendering engine, and in Fig.05 you can see my lighting setup for the render from the back. Here I have also outlined the rendering parameters that I paid most attention to before rendering.
These were the additional rendered elements:
Matte Shadow – to adjust the intensity and colour of the shadow;
Self illumination – to add a glow to the lights later on in the post-production stage;
Specular – to adjust the intensity of shine, or to add some glow to shiny areas;
ZDepth – to add depth to the image;
RenderID – to select and adjust separate parts of image in, let's say, Photoshop
So I took my images into Photoshop, made some colour correction, a few changes, and here is one of my final images (Fig.06).
Here is another render (Fig.07) in which I used only one Key light – no Reflection planes. The HDRI represents the photo into which I wanted to compose my render. I also modelled the rough environment geometry, which can be seen in the reflections, but rendered them as matte.
And the final one (Fig.08) was placed in a 3D environment that my friend gave to me. It was already textured and I only made some modifications to the geometry, changed the lighting and adjusted a couple of the environment textures.
