Description

A testing configuration used in RayTracingAccelerationStructure.CullInstances for adding Renderers to an acceleration structure based on their layer, ShadowCastingMode and Material type.

Typically, each ray tracing effect can use a dedicated RayTracingInstanceCullingTest configuration.

If the test passes, the value of instanceMask will be ORed into a final 8-bit ray tracing instance mask. When casting rays on the GPU using TraceRay HLSL function, the instanceInclusionMask argument of TraceRay is ANDed with the final 8-bit instance mask to include or reject ray tracing instances during acceleration structure traversal.

Additional resources: RayTracingAccelerationStructure.
