Dynamic Ambient Sounds
Hellscrag writes: DynamicAmbientSounds can greatly add to the ambience of a map. This Keypoint allows you to input a selection of OneShot sound effects that will be picked from and played at random intervals - this is how outdoor maps feature sporadic bird calls and buzzing flies. However, you can't adjust the volume and radius of these actors, so multiple DynamicAmbientSounds will be required in a large outdoor area.
