This texture pack was designed for use in 2D platformer games where you only ever see the texture from one direction. They are typically applied to a plane, cube face. They were created for use with platforms like Unity3D but should work in any 2D game.. They are certainly tileable, that's sort of the point but as they are not 'seamless' I classified them as non tileable. There are 50 terrain textures each image has both a transparent png file and CS5 PSD file.
