I was struggling to create those classic Japanese riverbanks with ai. You know, the ones you see in basically every anime ever. So I decided to try and create a lora for exactly that and here is the result! Now I have no idea if this will work, but we'll see haha.
You can try mixing and matching concrete_slope, grass_slope and cobblestone_slope, to create different variations of these sloped riverbanks.
