The mountain erosion node simulates the effect of fluvial erosion and rock weathering over a wide time span. The simulation produces results different from those of hydraulic erosion: more uniform carving on the slopes and less sedimentation. The user controls the strength of the erosion and the shape of the crevices that emerge.
To add a Mountain erosion node, right-click in the Graph Editor and select Create Node > Simulation > Mountain erosion.
This node only transforms an input terrain and does not output water or sediment layers.
Double click on the node to open its parameters:
Set the following parameters:
Most of the parameters can be driven by a mask provided by the user.
The tile being calculated is highlighted and surrounded by a red frame. This is only visible if the erosion parameters window is open.
|Number of iterations||Sets the number of iterations|
|Strength||Sets the strength of the erosion|
|Wrinkling||Controls the appearance of rivers and crevices on the slopes of the mountain|
|Smoothness||Controls the shape of the slopes|
|Automatic scale:||Automatically scales the terrain so that the result has the same quality as a terrain with a quad size of 1 meter|
Some combinations of parameters may lead to a divergent simulation.
