This section is perhaps the hardest to grasp but theres really nothing to it. Youre merely seeking a grayscale midpoint so that some buildings are taller than others When Bryce reads the heightmap. Were looking for a nice medium between the gradients of a possible 256-grayscale spectrum where each pixel can be equivalent to a different height on the heightmap. We limit this by posterizing 24 levels. This is further reduced when we adjust opacity to 50% and merge with the lower layer. Since there will be too many mosaic squares to handle, the sampler tool allows us to place a marker on those squares which come close to the 50% gray we need. The Total Ink panel allows us to view the pixels grayscale range in percentages rather than RGB pixels. BTW, the markers can be cleared while the tool is selected by clicking the clear button on the top tool menu.
