Difference: This
node subtracts one terrain from another terrain.
Average:
This node calculates the average value between two terrains.
Min: This node
calculates the minimum value between two terrains.
Max: This node
calculates the maximum value between two terrains.
Composition: This
node creates a linear composition between two terrains.
Full
composition: This node gives maximum freedom to compose two
terrains. The second terrain can be translated in the X and Y axis,
scaled, and rotated before composing it with the first
terrain.
Sum using
mask: This node adds one terrain to another terrain at the
locations defined by a mask.
Difference
using mask: This node subtracts one terrain from another
terrain at the locations defined by a mask.
Average using
mask: This node calculates the average between two terrains at
the areas defined by a mask.
Alpha-blend: This
node creates an alpha composition between two terrains at locations
defined by a mask.
Composition
using mask: This node creates a linear composition between two
terrains at locations defined by a mask.
Full
composition using mask: This node gives maximum freedom to
compose two terrains using a mask applied to the second
terrain.
