Weathered Concrete Texture.
Achieving this effect realistically with texture mapping can be difficult. Reagan McKenzie Design has created this texture from seven different high resolution images of vintage concrete walks. The images were painstakingly combined and optimized for color and texture.
This is a high resolution (1000 x 1000 pixels) professional architectural texture that will tile seamlessly in any direction. Diffuse, bump, and specular maps are included in JPEG format
