Terrain Inherits from MonoBehaviour

The Terrain component renders the terrain.

Variables

terrainData	The Terrain Data that stores heightmaps, terrain textures, detail meshes and trees.
treeDistance	The maximum distance at which trees are rendered
treeBillboardDistance	Distance from the camera where trees will be rendered as billboards only.
treeCrossFadeLength	Total distance delta that trees will use to transition from billboard orientation to mesh orientation.
treeMaximumFullLODCount	Maximum number of trees rendered at full LOD.
detailObjectDistance	Detail objects will be displayed up to this distance.
detailObjectDensity	Density of detail objects.
heightmapPixelError	An approximation of how many pixels the terrain will pop in the worst case when switching lod.
heightmapMaximumLOD	Lets you essentially lower the heightmap resolution used for rendering
basemapDistance	Heightmap patches beyond basemap distance will use a precomputed low res basemap.
lightmapIndex	The index of the lightmap applied to this renderer.
castShadows	Should terrain cast shadows?.
editorRenderFlags

Functions

SampleHeight	Samples the height at the given position defined in world space, relative to the terrain space.
AddTreeInstance	Adds a tree instance to the terrain
SetNeighbors	Lets you setup the connection between neighboring Terrains.
GetPosition	Get the position of the terrain
Flush	Flushes any change done in the terrain so it takes effect.

Class Variables

activeTerrain

Class Functions
