Ravines, crevices and mini canyons#29145

I thought for a long time what the new landscape lacks and realized that there are almost no erosion effects on the map.

For example - a small but deep and narrow ravine, like one at the sewer branch. One of it’s ends can be the cave entrance(hi, paroxum).

Grotto caves will be pretty good too.

Another way they could think of it would be erosion paths. So generate the terrain, find and generate primary erosion paths, generate cliffs based on erosion, generate cliff heightmap adjustments, generate secondary erosion paths that fit the new contours from the cliff heightmap adjustments.
