A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. Slumping is when a unstable pile of rubble settles into a more stable configuration, often bounded by its angle of repose.
Whereas Height Field Erode simulates erosion be iterating over animation frames, this node calculates and applies the effect of slumping all at once.
How many iterations of slumping to simulate.
How fast material spreads across the terrain.
The maximum slope, measured in degrees from the horizontal, at which loose solid material will remain in place without sliding.
Scales the height field before slumping.
The process of material lifting by an agent of erosion. Entrainment is the percentage of the entrained material that is dragged with the slumping material.
Allow Material Outflow
When material hits the edge of the terrain, does it flow out or accumulate there?
Add to Bedrock
Place material back into the bedrock (height layer) for further calculations such as erosion.
Calculate Flow Fields
Smoothing Iterations: Number of iterations to smooth flow.
Smoothing Rate: How fast smoothing occurs.
