Dual erosion sample

This sample creates a terrain both rock erosion and hydraulic erosion.

See Hydraulic erosion - Rock erosion

• The first step creates a base mask by multiplying a mask of the heights of a Perlin noise generator and a Circular symmetry mask.

• The base terrain is composed of three Perlin noise generators to which the base mask is linked through optional connectors. A series of connected transformation, composition, and generation nodes creates the output base terrain.

• The output base terrain is then linked to a series of seven nodes including Hydraulic erosion and Rock erosion to improve the shape of the terrain.

• A color map is imported and then applied to the erosion output terrain.

• Lastly, masks from the erosion output terrain's heights, slopes, angles, and curvature are exported.
