### Remarks

The [Plane](/engine/6000.0/script-reference/unityengine/plane.md) list is defined by [RayTracingInstanceCullingConfig.planes](/engine/6000.0/script-reference/unityengine/rendering/raytracinginstancecullingconfig/planes.md).

A Renderer in the Scene is accepted to the acceleration structure if its AABB lies completely or partially on the positive side off all the Planes in the list.
