Applies a Fake Erosion algorithm to eroded looking hills and valleys. The Streams output contains lines referencing where the erosion has been applied, where 0 means it has been eroded, 0.5f means nothing has happened and 1 means it has added.

• Size: How big the erosion should be
• Strenght: How much it erodes the terrain
• Detail Strenght: How much small erosions should impact the result
• Octaves: Steps to erode
• Lacunarity: Enabled if there is more than 1 octave. Defines how each frequency is scaled for the subsequent passes. Normally the value should stay around 2 to 10.
• Persistence: Enabled if there is more than 1 octave. Defines how much is the amplitude reduced between octaves.
• Stream Max Octave: Maximum octave to be taken into account and written into the streams map
