编辑LandscapeTerrain

The built-in Brush Editor allows you to change the Landscape Terrain relief on the spot with the help of brushes. In the editing mode, you can draw various terrain features, such as rocky ground and other craggy details. All brushes modify only the selected Landscape Layer Map.内置的画笔编辑器允许您在画笔的帮助下现场更改 Landscape Terrain 浮雕。在编辑模式下，您可以绘制各种地形特征，例如岩石地面和其他崎岖的细节。所有画笔只修改选定的 Landscape Layer Map。

To start editing a Landscape Layer Map, select Landscape Paint Mode on the toolbar.要开始编辑 Landscape Layer Map，请选择 Landscape Paint Mode工具栏.

You can also click the Brush Edit button in the Landscape Asset section of the Node tab in the Parameters window.您还可以单击 Parameters 窗口中 Node 选项卡的 Landscape Asset 部分中的 Brush Edit 按钮。

The Active Tool window will open:Active Tool 窗口将打开：

In the Objects section, there is a list of all Landscape Layer Map objects available in the world. To edit the required Landscape Layer Map, choose it either in the Objects section or in the World Hierarchy window.在 Objects 部分，有一个世界上所有可用的 Landscape Layer Map 对象的列表。要编辑所需的 Landscape Layer Map，请在 Objects 部分或 World Hierarchy 窗口中选择它。

After the LandscapeLayerMap texture asset is created, editing tools become available in the Parameters section of Active Tool.创建 LandscapeLayerMap 纹理资源后，编辑工具在 Active Tool 的 Parameters 部分中可用。

如果要编辑压缩后的地图，需要先解压，这可能需要一些时间，具体取决于地图的大小。

警告

当您使用有损算法反复解压缩/压缩数据时，每次压缩数据质量都会下降。

To reset all changes made to a Landscape Layer Map, Reimport all its data. 重置对 Landscape Layer Map 所做的所有更改，重新导入它的所有数据。

注意

Due to asynchronous nature of the Landscape Terrain system, insufficient streaming settings may result in undesired lagging of brushes while editing. Refer to the Landscape Terrain article for more details on the streaming settings.由于 Landscape Terrain 系统的异步特性，流式传输设置不足可能会导致在编辑时出现不希望的画笔滞后。有关流设置的更多详细信息，请参阅 Landscape Terrain 文章。
