Thermal simulates Thermal Erosion that can create talus and debris.
Using Thermal Erosion
Selective Processing
Like with the Erosion node, you can modulate how
Thermal Stress Anisotropy
Thermal Stress Anisotropy governs how erosion and the resulting rocks deposits are shaped. It smooths the terrain while eroding. Low values keep the original terrain intact for the most part, while high values create stronger talus at the expense of eroding the original terrain. For example, sharp peaks get eroded heavily with high stress values.
The image below shows a simplified version of how Thermal Stress Anisotropy affects a terrain.
Combining with Hydraulic Erosion
In the real world, hydraulic and thermal erosion occur together. You can mimic this behavior by chaining Thermal and Erosion (or Wizard) nodes, as shown in the Layering Erosion section in Eroding Terrains.
Selective Processing can be a very powerful tool in such a chain of nodes, for both Thermal and Erosion.
