Set the obstruction value of the path between two portals that has been created by Spatial Audio. The obstruction value is applied on one of the path segments of the sound between the emitter and the listener. Diffraction must be enabled on the sound for a diffraction path to be created. Also, there should not be any portals between the two provided ID parameters. The obstruction value is used to simulate objects between the portals that are obstructing the sound. Send an obstruction value of 0 to ensure the value is removed from the internal data structure.
