Occlusion Culling Planes not affected by non-uniform scale #18053

Occlusion Culling Planes not affected by non-uniform scale. For some areas we really need non-uniform scaling to help optimize our game and hide assets when they don't need to be seen.

Occlusion Culling Plane is a component that gets added to an entity and used to hide any assets behind it.

Occlusion Culling only works on PC as it was added via Intel's culling library. This is probably a legit bug but is not high priority given that it only impacts PC. There is an effort to add Umbra integration into O3DE which works on all platforms and is the preferred way to achieve occlusion culling. With Umbra you dont need to set occlusion planes and the developer process is quite simple as Umbra bakes the visibility data automatically.
