Set a global scaling factor that manipulates reverb send values. AkSpatialAudioInitSettings::fAdjacentRoomBleed affects the proportion of audio sent to adjacent rooms
and to the emitter's current room. This value is multiplied by AkPortalParams::AdjacentRoomBleed, which is used to scale reverb bleed for individual portals. When calculating reverb send amounts, each portal's aperture is multiplied by fAdjacentRoomBleed, which alters its perceived size:
- 1.0 (default): Maintains portals at their true geometric sizes (no scaling).
- > 1.0: Increases the perceived size of all portals, which increases bleed into adjacent rooms.
- < 1.0: Decreases the perceived size of all portals, which reduces bleed into adjacent rooms. Valid range: (0.0 - infinity) Note: Values close to 0 might cause abrupt portal transitions.
