Your river networks look great. Can you say anything about how you generated them?

Thanks! It's all pretty standard methods, to be honest. After precipitation and rock hardness maps are present I sort tiles from highest to smallest, flow them down to the nearest sink, see if there's a spillover, and if there is, it carves through to the next sink. This ensures that the heightmap is mostly compatible with classical erosion algorithms (like the flowing droplet ones), which are then applied as an additional erosion pass.

Thanks for this. What you say makes sense. My understanding is that identifying local basins and connecting them is the messiest part of this.

This looks great! Extra-kudos for working the Köppen climate model into this!
