Generates the height difference map. For each map pixel it calculates the average height delta to four nearby pixels. Could be useful for separating horizontal and vertical surfaces (to fill them with grass and cliff respectively).
Input: the default map to be processed by the generator.
Output: stores the generator’s processing result.
Steepness: defines the incline range that will be filled with slope map (in degrees). Minimum parameter sets the start incline of the stop, maximum - the end of the slope.
Steepness: 5-90, 35-90, 80-90
Range: how gradual will be a slope transition (in degrees)
