A simple way to invert a map. It's useful if you don't want to deal with curves for some reason. Mathematically it's 1-value algorithm, or, to be more exact, Level-value.
Input - the default map to be processed by the generator.
Mask - multiplies the generator intensity by the mask map’s value. For the mask pixels that have a value of 0 the generator effect is invisible, for the pixels that have a value of 1 the intensity is unchanged.
Mask, using the example of Blur Generator:
| Source heightmap | Mask map | Masking result |
Output - stores the generator’s processing result.
Level: subtrahend in invert algorithm. Determines the height of inverted map.
