Terrain.basemapDistance 底图距离

var basemapDistance : float

Description描述

Heightmap patches beyond basemap distance will use a precomputed low res basemap.

高度图面片超出底图距离将使用一个预先计算的低解析度底图。

This improves performance for far away patches. Close up Unity renders the heightmap using splat maps by blending between any amount of provided terrain textures.

这个可以提高远处地面的性能。近处Unity渲染高度图使用溅斑贴图，通过混合任意数量的地形纹理。

function Start () {
	Terrain.activeTerrain.basemapDistance = 100;
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	void Start() {
		Terrain.activeTerrain.basemapDistance = 100;
	}
}
