Creating oceans and lakes

The Ocean and Lake tools use specialized sculpt brushes that create valid water/coast transitions while shaping terrain depth.

Controls

Both tools expose brush shape, angle, size, W/H proportions, depth, smoothness and coastline country. The coastline country can be selected from the country picker, picked from an existing map cell or cleared.

Ocean versus lake

• Ocean marks deep water/coast cells and assigns ocean-related sounds automatically (for example Ocean, Splash and Coast according to depth/proximity).
• Lake uses lake semantics: deep cells receive Lake ambience and shallow/coast cells receive Slow Waves.

The brush also maintains cell water/coast flags and adapts neighboring elevations to create the required transition levels.
