SFX

SFX is for short sounds that should play once.

Use Insert > Playback & Flow > SFX for clicks, impacts, bells, short stingers, and other moments that do not need a looping audio track.

Properties

Inherited/common properties

Field	What it does
Name	Optional label used in the editor and Story Map. Leave it empty to use VNC's automatic node name.
Sound	Audio asset to play once.
Next	Node that runs after this node finishes its own work.
Volume	Playback volume. Use 0 for silent and 1 for full volume.
Playback Speed	Playback speed greater than 0.

Runtime Behavior

When the node runs, VNC sends a one-shot sound request to the presentation state and then continues to Next. The story does not wait for the sound to finish.

If the audio asset is missing, Properties and Output should warn so you can import or choose a valid asset.

Example Setup

Field	Example value
Sound	sfx/story/punchHeavy
Volume	0.65
Playback Speed	1.15
Next	the next node in your route

Use dialog cues for text-timed sounds

If a sound should trigger when a specific word appears during typewriter text, use a Dialog cue instead of placing an SFX node nearby.

SFX nodes are best for clear beats between story actions. For background music or ambience, use an Audio node.
