Parameters 参数

renderer	The Renderer to use when searching for a system to update.
terrain	The Terrain to use when searching for systems to update.

Description 描述

Schedules an update of the albedo and emissive textures of a system that contains the renderer or the terrain.

预设更新反射率和发射贴图的系统，包含渲染器或地形。

The third overload specifies a region of the terrain that needs to be updated. This makes sure that only the systems that overlap with the specified rectangle get updated, which could help improve performance. The coordinates are specified the same way as in TerrainData.SetAlphamaps.

第三个重载指定需要更新的地形区域。这可以确保只有指定的矩形重叠的系统得到更新，这可能有助于提高性能。指定坐标的方式于TerrainData.SetAlphamaps是一样的。
