Take On Mars just 'took off' in terms of visual quality when it comes to blending of terrain materials. Seen in the 'Before' and 'After' screenshots, we have implemented a new method of terrain material blending.
In the 'Before' screenshot, we used blending by means of the alpha channel, which meant materials 'faded' into each other. In the 'After' screenshot however, we used blending by means of height data. This means that rocks that are tall in the material will be realistically blended through the top of the sand material below, resulting in a visually impressive, and more realistic appearance.
