Fractal weight
The fractal weighting at each point in the heightfield is controlled by the 'frac' parameter of each pixel in the design map. The FractalWeight parameter in this filter may be used to increase or decrease the overall fractal noise used for the inflation levels across the whole map. Typically, for late-stage inflation near the final resolution of the heightfield, the fractal weighting is decreased to 50.
