BuildItSolar: Solar energy projects for Do It Yourselfers to save money and reduce pollution. Alternative Energy - Windhunter. Oliver Charles: Stockholm Library Design. The UV's are simple, just an 'unwrap' for the concrete.
In fact, the concrete is the scene's main material. I made a custom diffuse map, started from pictures in Photoshop, and after, from the diffuse, the reflection map, and the normal bump with some handmade joint (a grayscale image converted in normal bump with the NVIDIA Plug). I used the mrarchi&design material, for easy control of the glossy reflections. I like this material because it's really complete. I use mental ray for this rendering, because I've a good control of the color balance and levels adjustment with this engine (in my opinion, better than V-Ray, there's less color aberration with mental ray, and I'm not in a hurry for this image).
