Description

Causes RayTracingAccelerationStructure.CullInstances to perform solid-angle culling.

The minimum solid angle in degrees is defined in the RayTracingInstanceCullingConfig.minSolidAngle property, and its apex is defined by the cameraPosition value from RayTracingInstanceCullingConfig.lodParameters.

A Renderer in the Scene is accepted to the acceleration structure if its solid angle is larger than RayTracingInstanceCullingConfig.minSolidAngle.
