Hello again :)
I'm using voice over dialogues, however every time the voice files plays the music volume lowers a little bit by default. Is there a way to change this?
I need the music to be unchanged at all times. I tried to fiddle with sound priorities, volumes and all that, but nothing works.
Check the VolumeReductionWhileSpeechPlaying property under AudioTypes | Music. (Yes, this ought to be documented in the manual, but it doesn't have entries for Editor settings that can't be set programmatically.)
