Reference - FMOD Parameters

The following tables list the different parameters to use with the Sound_ParameterTransition_V2_BP_C Blueprint to modify Ambient and Music queues within your level.

[D] = Dynamic parameter: These are layers that can be toggled between different states multiple times, and transition between them freely. Usually if x parameter = 1, a layer’s volume is brought up, if 0, it’s back down again.

[S] = Static parameter: These are single use events that are one and done, you cannot trigger them again after the initial firing. These are used for timelines that have some linear progression to them or trigger a sting event (eg: seeing the pictures on Streamer). Once it’s triggered, it shouldn’t be set back to 0. You cannot go backwards on the music timelines once these are called.

FMOD Events Parameters are NOT case sensitive. Spaces in some names are required however.

1. The timeline will only continue properly if FarmMusicENTRY == 1. As FarmMusicENTRYAPPROACH increases to 1, a choir layer is increased in volume - this layer only plays during the intro section.
2. Once FarmMusicENTRY == 1, a large drum hit will play, and the timeline will continue.
3. Using the assorted drone parameters, different layers can come in and out
4. To have the church approach section play, set FarmMusicCHURCHAPPROACH to 1. As long as the Farm_Music_Spatial_Drum FMOD event is placed in your map, you should hear this drum play spatially now.

HospitalDEPTH3	[S]	””
HospitalDEPTH4	[S]	””
HospitalDEPTH	[D]

• The SPOTTED events are meant to be used for spotting things like bullet holes, blood and dead bodies
• The way Hospital works, is that the Transition Volumes are set up so as you go deeper it adds more layers.
• Since there are different spawn locations on different sides of the map, Hospital sets up multiple Transitions, for example Depth2, so no matter which side you enter from it will always trigger. It continues to cascade Transitions in-wards from opposite sides as you continue to move deeper through the map.

There are 6 FMOD events that you can place if this music is used, that have synchronized beeps to the music (Hospital_OST_Beeps_1 - 6)
