Changes the intensity (brightness) and the contrast of the input map. Could be useful for the simple modifications of various masks.
Increasing contrast to large values (100-1000) will return single-bit masks, with only 0 or 1 values and no gradients (or almost no gradients).
Increasing contrast of the Noise and grass texture masks
Intensity: changes the height (or brightness, if considering map is an image) of the map. Ranges from -1 (any input map would be black) to 1 (any map would be white).
Intensity: -0.5, -0.25, 0, 0.25, 0.5
