-The SOMA Level Editor toolbar documentation includes Terrain EditMode for creating and configuring terrain.
+A '''terrain''' is an editable height-mapped surface created inside the SOMA Level Editor. It is useful for large continuous ground such as a seabed or an outdoor landscape. Terrain has separate tools for shaping its height map, painting materials, adding terrain decals, and placing undergrowth.
-HeightMap mode provides Raise/Lower, Flatten and Smooth brushes. The existing terrain documentation also describes terrain generation and heightmap import/export.
+{{note|Create terrain in a map inside your mod, not in one of SOMA's original maps. Creating a new terrain cannot be undone and clears the editor's undo history. Save the map before opening the creation dialog.}}
