Surface Terrains
This terrain type modifies the landscape surface properties - color and texture - only. Surface textures are placed on the landscape using vector shapes such polygons or lines. This terrain type is usually used to add man-made features such as roads, or define fields of different crops, but can also be used to define rivers.

Surface Colors

• Override defaults: If checked these colors are used, otherwise the default colors defined by the terrain color and texture editor are used..
• Handle as Water: If checked this terrain area will be rendered as water. This option should be primarily used for rivers as areas of open water are better handled by flooding using the landscape editor.
• Surface Colors: Surface colors used for this terrain. Distributions between the two colors depends on local surface conditions and the Bias setting in the terrain color and texture editor.

Surface Properties

• Override default surface properties: If checked these properties are used, otherwise the default surfaces defined by the terrain color and texture editor are used..
• Bumpiness: Small scale surface roughness. This value controls the texture roughness, not the actual surface roughness.
• Shininess: The amount of light reflected by the surface.
• Specularity: Highlight reflections - how gloss or matt the surface appears.
• Emission: Emission characteristics. Not normally used, but useful for highlighting areas, lava flows or other special effects.
