With this texture pack we wanted to focus on more advanced techniques used for rendering realistic scenes in real-time. The focus was on the creation of realistic surfaces.
Each of these textures includes a diffuse, normal, displacement, and specular map making them perfect for a bump mapping or parallax shader, but they look great even with no shaders applied!
Shown below are renders of each set of textures in parallax on a sphere. Note: textures fully tile.
