131 seamless rock & stone texture files (png) format in a zip file. The texture size is 512x512. You can use these textures on objects and they will tile seamlessly. Some files are alpha channeled. When tiling the textures, it is very difficult to tell where it starts and where it ends. This is a great resource for game developers and 3D modelers. I currently am working on a computer game and I always seem to have a hard time finding the right textures that can tile seamlessly, so I decided to make my own and they turned out great.
