Sounds
Made with	Functional > Create Point Sound; any brush with Is Sound Volume; Map Config > Soundscape
What it is	Sounds at a point, ambient sound in an area, and map-wide background audio
In the game	Yes, it is exported with the map

A map can carry three kinds of sound:

• A point sound plays from one spot and gets quieter with distance: a humming machine, a waterfall, a radio.
• A sound volume plays while a player is inside an area: the wind on a rooftop, the drip of a cave, the hum of an engine room.
• The soundscape plays everywhere, whatever a player's position: music or general ambience. It is set in Map Config > Soundscape.

Your own sound files (.wav, .ogg, .mp3) come in through File > Import Custom Asset... or the Import External File… button of the sound picker, and are packed into the map's export. See Custom assets.

Point sound

1. Choose Functional > Create Point Sound.
2. Click where the sound comes from.
3. In the inspector, click Stream to pick a sound.

Inspector (the standard positional sound settings; the most used):

Setting	Type	Default	What it does
Point Name	Text	empty	A label shown above it in the editor.
Stream	Sound	none	The sound to play.
Volume Db	Decibels	0	Loudness. Negative is quieter.
Unit Size	Number	10	How far the sound carries before it starts to fade. Larger is heard further.
Max Distance	Meters	0 (no limit)	Beyond this the sound is not heard at all.
Pitch Scale	Number	1	Plays the sound faster and higher, or slower and lower.
Autoplay	Check box	Off	Start playing when the map starts.
Attenuation Model	List	Inverse	How the sound fades with distance.

To loop a sound, use a sound file set to loop.

Sound volumes

Any brush can be a sound volume, so the area can be the exact shape of a corridor or a room rather than a box.

1. Build a brush of the area's shape.
2. Tick Is Sound Volume in the inspector. The brush is no longer solid or visible in the game.
3. Set its sound settings.

Setting	Type	Default	What it does
Sound Name	Text	empty	A name for the sound volume.
Stream	Sound	none	What plays.
Volume Db	-60 to 6 dB	0	Loudness.
Pitch Scale	0.01 to 4	1	Playback speed and pitch.
Autoplay	Check box	On	Play automatically.
Loop When Inside	Check box	On	Keep the sound looping while the player is inside the volume.

A brush cannot be a zone and a sound volume at once. Edit > Click Through Sound Volumes lets you click what is behind them.

Sounds of doors and buttons

Doors and buttons pick their sounds from the game's own sound list (type to search it), not from imported files.
