The tail Lights.

Light clusters are difficult to get looking right and as much time and effort should be spent making the components as the rest of the car after all these are one of the main focal points and are often neglected in the build process and can spoil the final look of the work. Above shows the light being built up in its different layers fig a is the reflective chrome base, Fig b shows the equivalent of the inner face of the tail light cover and fig c is the outer face of the tail light cover Below shows an exploded view of the tail light cluster the materials used are: chrome for the reflector and bulbs and a various glass materials for the cover an IOR of 1 is used on the glass initially but can be adjusted to help get the desired results.

Below is the the rendered version of the tail light in a scene the grill effect is created using a bump map similar to the grill below in the bump slot and a coulred version in the glass filter colour (brazil r/s)

The headlightsThese are constructed in exactly the same way as the tail lights in their individual components. another essential in making light clusters is spending time on the materials. In the image below as on the real thing you can see the refection of the headlight indicator in the chrome surround the reflection is slightly blurred giving it a softer more realistic feel, fresnel falloff is also used to give control of the intensity of the final reflection.

Disk BrakesBelow shows the settings for both the glossy reflection and the specular type used on the disk brakes, the higher than default sample rate although unlucky for some seems to work well at reducing the artifacts that were present at the lower values. The highlight shader (specular) is set to blinn and uses an Anisotripic effect this is seen where the high light is distorted by the brushed surface of a material.
