Use the Occlusion Area component to define View Volumes in the occlusion cullingA that disables rendering of objects when they are not currently seen by the camera because they are obscured (occluded) by other objects. More info
See in Glossary system. View Volumes are areas of the SceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary where the CameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
See in Glossary is likely to be located at runtime. At bake time, Unity generates higher precision data within View Volumes. At runtime, Unity performs higher precision calculations when the Camera’s position is within a View Volume.
If you have not defined any View Volumes in your Scene, Unity creates a View Volume at bake time that contains all Scene geometry that is marked as Occluder Static or Occludee Static. This can lead to unnecessarily large data size, slow bake times and resource-intensive runtime calculations in large or complex Scenes. To avoid this, place Occlusion Areas in your Scene to define View Volumes for the areas where the Camera is likely to be.
|Set the size of the Occlusion Area.

|If enabled, the Occlusion Area defines a View Volume. If disabled, the Occlusion Area does not define a View Volume. This must be enabled for an Occlusion Area to work.
