Obstruction value for this path This value includes the accumulated portal obstruction for all portals along the path. In the case that no valid diffraction paths are found, this value is set to 1.0. The obstruction value sent to the sound engine is normally calculated from the result of the diffraction calculation, and then max'ed with the portal obstruciton value. If no path is found between the emitter and listener or if the maximum path length for a given sound is exceeded, the sound engine is sent 1.0 for obstruction. In this case obstructionValue is set to 1.0, and nodeCount is set to 0. The maximum path length for an emitter is defined in AkEmitterSettings.
