Biomes

Swamps
To generate a swamp-alike biome, use the spray to generate the water using the (custom) River layer, making sure the water is sufficiently connected.
Next, apply the ground cover on this River layer. While you can use the River Terrain other cover can be chosen as well if it doesn’t fit the swamp design.
To add water plants, create another custom terrain which contains the water plants as well as regular water. Then create a layer using the newly created custom terrain, with thickness set to -1, and apply that to the River layer.
Deserts
To make better-looking deserts, have height difference around 25 across the desert. Use slopes between 15 and 30 degrees.
