Occluder Mesh

Occluder Mesh is an occluder which is based on an arbitrary mesh. Occluder Mesh is used to cull objects' surfaces, bounds of which are not visible behind it. The surfaces behind the occluder are not sent to the GPU, thereby saving performance.Occluder Mesh是基于任意网格的遮挡物。 Occluder Mesh用于剔除对象的表面，其后部的边界不可见。封堵器后面的表面不会发送到GPU，从而节省了性能。

Before adding Occluder Mesh to a scene, you should prepare a mesh, on which this Occluder Mesh will be based. Such mesh is created separately and should be as simple as possible: it should contain the minimum number of polygons.在将Occluder Mesh添加到场景之前，您应该准备一个网格，该Occluder Mesh将基于该网格。此类网格是单独创建的，并且应尽可能简单：它应包含最少数量的多边形。

When the mesh is prepared, you can add Occluder Mesh to the scene via UnigineEditor:准备好网格物体后，可以通过UnigineEditor将Occluder Mesh添加到场景中：

1. Run the project with UnigineEditor.跑步UnigineEditor的项目。

2. On the Menu bar, click Create -> Optimization -> Occluder Mesh.在菜单栏上，单击Create -> Optimization -> Occluder Mesh。

   

3. In the file dialog window, choose a mesh (*.mesh), on which the occluder will be based.在文件对话框窗口中，选择遮挡物将基于的网格（*.mesh）。
4. Place the Occluder Mesh in the world and specify the required parameters for it.将Occluder Mesh放置在世界上，为其指定所需的参数。

注意

To display the buffer that is used for occluders rendered in the viewport, pass 1 to the render_show_occluder console command.显示缓冲用于在视口中渲染的遮挡物，请将1传递给render_show_occluder控制台命令。

Example例子#

For example, if you have a building that occludes some objects' surfaces, you should prepare a simplified mesh to be used as a base for the Occluder Mesh instead of using the detailed mesh.例如，如果您的建筑物遮挡了某些对象的表面，则应准备一个简化的网格作为Occluder Mesh的基础，而不要使用详细的网格。

Mesh that represents a building and contains a lot of details代表建筑物并包含许多细节的网格	Occluder that is based on the simplified mesh and is rendered into a separate buffer with a low resolution基于简化网格的Occluder并渲染到低分辨率的单独缓冲区中

In the Node tab of the Parameters window, you can adjust the following parameters of Occluder Mesh:在Parameters窗口的Node选项卡中，可以调整Occluder Mesh的以下参数：
