Actualités. Stockholm Library Interior. 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.
