For the tire I started by designing one segment of the tire's pattern, then I repeatedly duplicated and bent the original pattern 360 degrees (Fig.07). The tire's brand was first created in Photoshop, and then a bump map texture was applied (Fig.08).



For the headlights, the most important point was the complex look of the glass refraction. I made the glass design in a duplex surface. As you can see in Fig.09, I applied a general glass surface for the first layer and a bump map texture for the second glass.


The bump map texture was made using the Gradient tool in Photoshop (Fig.10).

Lighting

I used real studio light settings and created a scene that I could refer to (Fig.11).


Here are the lights that I used (Fig.12 – 14):

1. V-Ray light – helps to create the ambience and reflections within the scene
2. V-Ray light – bounces off a spherical object and creates soft lights
3. V-Ray light – bounces off a spherical object and creates soft lights
4. V-Ray light – bounces off a spherical object and creates soft lights
5. V-Ray light – I searched for the areas where it looked too dark or had little reflection and decided whether or not I needed to add or take out more light.
6. Spot light – I made the background brighter to help separate the car from the background.  I also added color to the light to create an overall atmosphere.

Because I wanted to make a soft reflection, I made sure that the V-Ray light's Diffuse was on and that the Specular and Reflection were both off.






The shape of the Hummer is not round, but rather it has a flat shape. So, I used the method mentioned above to try and create a softer reflection, and in turn create an image that has more volume (Fig.15).


Even if there was a studio filled with people on set who were able to catch every angle of the scene, it would still be hard work. I had to constantly remember to set the light according to where I was going to set the camera.
 
And here's the final image (Fig.16).

This outlines the progress of my work, and I hope that it is a helpful resource for you.  Thank you very much!
