There are both flat and sloped ground surfaces on which the game characters traverse. In areas where a sloped surface changes angle (i.e. where a sloped surface connects to a flat surface), a transitional method has been created to make the adjoining textures on the top surface area of the ground blend together seamlessly. A unique texture is used for this purpose. This texture uses the same material as the flat “ground trim” texture seen on the top of every surface. The texture has a diagonally drawn alpha mask that blends from completely transparent to completely opaque from the bottom right corner of the texture to the top left corner. When this texture is drawn at the ends of each sloped surface where they change angle, the combination of the color channels and the alpha mask line up with adjoining textures to blend them together and create a seamless visual transition.
