Sculpting the landscape

The Sculpt tool applies a reusable brush to terrain elevations and can also assign countries, coastline/cliff materials and sounds while shaping.

Brush controls

Brushes can be saved, added and removed. Shapes are Circle and Triangle. Size defines the major dimension; W/H change the aspect ratio. The angle can follow the camera or use a fixed offset. Flow controls editing speed and Smoothness controls the feathered edge.

Sculpt modes

Mode	Behavior	Shift behavior
Absolute	Moves cells toward the configured absolute elevation.	Drives cells away from the reference elevation toward the available extremes.
Relative	Adds the configured elevation delta to the height present at stroke start.	Subtracts the delta.
Flatten	Uses the elevation under the stroke start point as a flat target.	Moves cells back toward the heights recorded at stroke start.
Smooth	Moves each cell toward a weighted average of neighboring heights.	Produces the inverse effect (local sharpening).
Terrace	Quantizes terrain into elevation steps using the configured elevation as the terrace interval.	The terrace target remains quantized; the modifier still affects directional water/coast handling.

Terrain constraints and automatic painting

• Max slope limits the allowed height difference to neighboring cells for most sculpt operations.
• Max depth limits how deep the brush can cut into water levels.
• Normal / cliff / coastline countries can be assigned while sculpting. Cliff classification uses the configured cliff slope.
• An optional sound can be painted on ordinary land while water-related cells receive appropriate automatic water/coast sounds.
• Changed blocks have heights fitted to LND storage precision and shadows are recomputed at the end of the stroke.
