Solve common problems when using occlusion culling, such as incorrect culling and slow processing.
Objects are reported as visible in the occlusion data but are visibly occluded.
Culling in Unity operates conservatively. This means that unless the object is explicitly set as invisible, Unity will assume objects are visible.
Occlusion data represents a conservatively simplified version 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’s occluders, meaning some of the occlusion erodes and loses detail.
Decrease the value of the Smallest Occluder parameter. This will produce higher-resolution data that is less conservative. However, culling will decrease in speed and occlusion data will increase in size.
Objects are occluded incorrectly.
The culling process is too slow.
Increase the value of the Smallest Occluder parameter.
The baking process is too slow.
Increase the value of the Smallest Hole parameter.
The size of the occlusion data is too large.
Baking fails with the Failure in split phase error.
The initial step of the bake tries to subdivide the scene into computation tiles. The subdivision is based on the Smallest Occluder parameter and when the scene is large in size, too many computation tiles can be created, resulting in an out of memory error.
Increase the value of the Smallest Occluder parameter and split up the scene into smaller chunks.
