Today, I uploaded a zip file contains (42) seamless 256×256 pixel texture maps of asphalt and (27) seamless 512×512 pixel texture maps of asphalt at Turbosquid. It can be found at http://www.turbosquid.com/FullPreview/Index.cfm/ID/565252?referral=mastermesh
These images are cropped from a few photos I’ve taken of asphalt from a while back. I have decided that going forwards, I am going to try to do zip file collections of seamless texture maps because it’s not too difficult to crop the images or make them seamless. In the past I uploaded raw photos that were not cropped or edited. I have decided that these sort of photos might be a bit more useful if cropped and seamless so that my loyal customers and the product’s end users won’t have to work as hard to make the images usable in their game engines and other 3d applications.
The pixel widths are 256×256 and 512×512 pixels so that the image ratio is a power of two, something that many 3d applications and game engines need to render the images proportionally correct.
