This is a 1024x1024 tilable asphalt texture complete with normal map and specular map. The normal map is not a simple photoshop convert, it is the result of a high res 1,000,000+ poly mesh being converted. This provides the most accurate (and by far best looking) normal map available. The specular map is designed to only reflect light in the pieces of the ashpalt that should, like the little quartz specs. The example image is a real time shot from maya displaying the tangent space normal effect with a single point light, and a low intensity ambient light just for back lighting. You can download a higher quality version to really see the detail in this image below in the preview section. This scene is included with the files as well. You can see how the maps are hooked up and used inside of maya, and apply it to your 3d package of choice.
