When to use
Place it after the broad silhouette. Tune at a lower preview resolution, then inspect the final result at higher resolution.
Example connection:
Compatible source → Coastal Erosion → Autolevel/Blend → Build Map
Notes
Heightfield outputs are sampled at the active preview resolution and at terrain-voxel density during a build.
This node performs neighborhood analysis or repeated simulation work. Tune it at a lower preview resolution when interactive updates become slow.
