VketBGMFader

Overview

This is a prefab that can play audio, such as when a player enters the exhibition space. When a sound source is set, it fades in to replace the world BGM. The fade-in effect of the audio can be specified in the range from 0 to 1.0. The audio is played locally, stops when the player leaves the booth, and the world BGM fades back in.
The fade can also be controlled via UdonEvent.

About the sound volume

Please adjust the Volume of the AudioSource or the sound source file by referring to the sample sound source file packaged together. The Vket staff may adjust the file if the sound is excessively louder than desirable.
