| layerMask | A 32-bit mask that specifies which layers to remove ray tracing instances from. |
| rayTracingModeMask | A mask that speficies which RayTracingModes ray tracing instances must have in order to be removed. |
Removes ray tracing instances from the RayTracingAccelerationStructure using filtering based on layer and RayTracingMode.
