Paint Terrain

Paint Terrain tools let you use a Brush to sculpt or paint the Terrain and make modifications. The Terrain Tools package adds 13 additional tools to the 6 built-in tools, and improves the functionality of the built-in Paint Texture, Smooth Height, and Stamp Terrain tools.

In the Terrain Inspector, click the Paint Terrain icon to display the list of Terrain tools.

The Terrain Tools package provides the following 13 additional tools, and improved Paint Texture, Smooth Height, and Stamp Terrain functionality.

• Bridge creates a Brush stroke between two selected points to build a land bridge.
• Clone duplicates Terrain from one region to another.
• Noise uses different noise types and fractal types to modify Terrain height.
• Terrace transforms Terrain into a series of flat areas like steps.
• Contrast expands or shrinks the overall range of the Terrain height.
• Sharpen Peaks sharpens peaks and flattens flat areas of the Terrain.
• Slope Flatten flattens the Terrain while maintaining the average slope.
• Hydraulic simulates the effect of water flowing over the Terrain and the transport of sediment.
• Thermal simulates the effect of sediment settling on the Terrain while maintaining a natural slope.
• Wind simulates the effect of wind transporting and redistributing sediment.
• Paint Texture is similar to the built-in Paint Texture tool, but with added functionality such as an improved workflow and a Terrain Layer Eyedropper tool.
• Pinch pulls the height towards or bulges it away from the center of the Brush.
• Smudge moves Terrain features along the path of the Brush stroke.
• Twist rotates Terrain features around the center of the Brush, along the path of the Brush stroke.
• Smooth Height is similar to the built-in Smooth Height tool, but includes two new parameters, Verticality and Blur Radius, which provide finer control when smoothing your Terrain.
• Stamp Terrain is similar to the built-in Stamp Terrain tool, but with added functionality such as Min and Max operations that provide finer control over Terrain. It now also includes the Mesh Stamp tool, which projects the shape of a mesh into the Terrain's heightmap.

You can also create your own custom Terrain painting tools. For more information, see TerrainAPI.TerrainPaintTool and Create a custom Terrain tool.
