More on bump maps
Bump maps on plaster, metal, stone, and mortar.
The image below was made in Maya and rendered with mental ray. The plants inside the building were made with PlantFactory.
The blue and white plasters were made with two seamless plaster textures used as the color of two mental ray materials. Each material has a bump map made from the plaster texture used for its color.
The roof of the structure was made with a gold steel seamless texture used as the color of a Blinn. The reflectivity, eccentricity, and specular rolloff were cranked up to make the material shiny. The same gold steel texture was used to give the roof a deeper sense of depth.
