Big changes are coming on the musical side of the game. First of all, we're now officially using Wwise, from Audiokinetic. It's a powerful tool that'll give us the ability to push the music integration to another level.
Let me show you in this video how we can create dynamic and evolutive musics on our planets:
The first half of this video concentrates on the differences between normal musics and underwater musics. When the player goes underwater, the instruments and rhythms change. Even some melodies change a bit ! But the two tracks share the same structure, so all the transitions are smooth.
It's the same system in the second half of the video with the day-night cycle. With these long musics (8 to 10 minutes each) and all these dynamic changes, the musics will never feel the same during our planetary explorations.
Next step : make the same thing for the day-night ambience.
