DetailRenderMode.GrassBillboard 草的面向板

DetailRenderMode.GrassBillboard

Description描述

The detail prototype will be rendered as billboards, so always facing

the camera. Grass will take normals from terrain directly underneath it, so that the shading matches the terrain.

细节原型将被渲染为billboards方式，因此总是面向摄像机。草将从地形正下方采取法线，因此着色匹配地形。
