A heuristic to stop the computation of reflections, and reduce the search space for reflective surfaces. Should be no longer (and possibly shorter for less CPU usage) than the maximum attenuation of the reflections, as defined in the AkReflect plug-in. Setting
reflectionMaxPathLength is critical for performance. This value should be set as small as possible to reduce the number of possible surfaces to consider for reflections. Setting
reflectionMaxPathLength to 0.f effectively disables reflection processing for this sound emitter.
