Lighting. I decided to go for a studio light setup that I have seen many times. This is used a lot on cars in real life. So if its good enough for them its good enough for me :). In image 7 you can see I have created a large box above the truck, this is the emitter. Being big it creates nice soft shadows and also nice reflections on the body work. It has a maxwell emitter tag set to, colour+luminance. Emitter intesity set to 2000 and Emitter efficiency to 12.7. Power [w] and colour was set to white. Once I set the render off I adjusted the shutter to either make the image lighter or darker (very handy being able to do this while rendering).

Step 4 :
The camera was set to 0.017 shutterspeed, 100 iso, and fstop of 4. like I said you can adjust it in the render while rendering.
Step 5 :
For the render settings dialog I just made sure it was set to low priority by adding the p:low to the command line. I then made sure it was using 2 cpu threads and had enough time to render.
Well thats about it. I will write another small tutorial on how I lit the flashlight version this truck. I hope it will help someone.
