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.

See Also: RayTracingAccelerationStructure.

allowOpaqueMaterialsWhether to allow Renderers that use opaque Materials.
allowTransparentMaterialsWhether to allow Renderers that use transparent Materials.
instanceMaskAn instance mask which affects ray-instance masking during ray tracing on the GPU.
layerMaskA value that indicates which layers are accepted by this testing configuration.
shadowCastingModeMaskA value that indicates which ShadowCastingMode values are acccepted by this testing configuration.
