DS4P -> Reality/LuxRender
The pink car texture is done with Lux's native carpaint material. The settings are based on the 'Solaris Silber' preset, with the diffuse changed to a pink colour. Most of the rest of the car is set to Lux's metal2 material.
The race babe's suit is using the new experimental cloth material in Lux. As it's not a close-up, you can't see the individual threading that the material simulates, but this should give some idea of how its reflectivity/specularity behaves. It's using the polyester_lining_cloth weave preset.
I also used the new user sampling map feature in Lux to get it to focus on the water in the fountain after the first 1500S/p or so, as the water was particularly noisy. It is still a bit noisy, truth be told, but I've sunk so much time into this render experimenting with the new Lux beta, it's time to move on. (I let it run for a fair while with the new noise aware option as well, but that resulted in blotches showing up in the car paint, so had to be scrapped.)
