- Can I control the volume of a bus in code? (for example to set the volume of Music, Speech, etc)
The Wwise API doesn`t allow you to control the volume (or other properties) of busses, containers, sounds, etc. directly. Instead, you can use the RTPC system to control those properties in the code. ...
