Description描述

Returns an array of all supported detail layer indices in the area.

The Terrain uses a detail layer density map. Each pixel in the map the amount of details objects that will be procedurally placed in the pixel area. The layer determines the detail prototype that will be instantiated at the location.

地形使用一个细节层密度图，在贴图中每像素细节物体数，将被程序放置在像素区域。该层确定细节原型将被实例化的位置。
