转换和通用参数

When switched to Immovable the node is moved to a separate spatial tree for immovable (static) objects optimizing node management. Using this parameter can improve performance. Immovable is set by default. Switch the Mobility of the node to Dynamic, if you intend to move a node, assign a physical body to it (other than Dummy Body) to make it physics-driven, or make any other changes affecting the spatial tree (see below).切换到 Immovable 时，节点将移动到单独的空间树中，用于优化节点管理的不可移动（静态）对象。使用此参数可以提高性能。Immovable 是默认设置的。将节点的 Mobility 切换到 Dynamic，如果您打算移动节点，请为其分配一个物理实体（Dummy Body 除外）以使其由物理驱动，或进行任何其他影响空间树的更改（见下文）。

There are several restrictions on nodes considered immovable. Any action affecting the spatial tree is prohibited and causes a warning: you cannot change the node state (enabled/disabled), surfaces, bounds, transformation, visibility distance, as well as move the node, assign a non-dummy physical body or even change the Mobility state as it also leads to rebiulding of the spatial tree.对于被视为不可移动的节点，存在一些限制。任何影响空间树的操作都是被禁止的，并且会引发警告：您不能更改节点状态（启用/禁用）、表面、边界、变换、可见距离，也不能移动节点、分配非虚拟物理实体，甚至更改 Mobility 状态，因为这也会导致空间树的重建。

Enables occlusion query for the objects. The objects are tested whether their bounding boxes are seen. It allows reducing the number of rendered triangles, which is beneficial by using heavy shaders. This option provides the substantial performance gain when enabled for water or meshes with reflections.

注意

Enable this option only for a few nodes that use heavy shaders; otherwise, the performance will decrease instead of increasing.Enable this option only for a few nodes that use heavy shaders; otherwise, the performance will decrease instead of increasing.

Culling will be performed if the hardware occlusion query test is enabled for the scene (the Rendering -> Occlusion Culling -> Occlusion Query flag is set).Culling will be performed if the hardware occlusion query test is enabled for the scene (the Rendering -> Occlusion Culling -> Occlusion Query flag is set).

注意

Enable this option only for a few nodes that use heavy shaders; otherwise, the performance will decrease instead of increasing.仅对使用大量着色器的少数节点启用此选项。否则，性能将下降而不是提高。

Culling will be performed if the hardware occlusion query test is enabled for the scene (the Rendering -> Occlusion Culling -> Occlusion Query flag is set).如果为场景启用了硬件遮挡查询测试（设置了Rendering -> Occlusion Culling -> Occlusion Query标志），则会进行剔除。
