I would absolutely love some kind of portal system like this - I’ve currently been making my own awkward workaround, involving lots of transceivers, automating sound size, and tracking distances between points in engine, but it would be extremely difficult to scale up and is very error prone. It also seems to me to be one of the main benefits of using Wwise which is a shame, because otherwise I really enjoy using FMOD!
Essentially, what I do now is this:
- I have one main area, with two small buildings in it
- All ambience is played and sent via transceivers to the doorways of these buildings, and a final gain plugin at the end of the chain mutes this event (so it can only be heard via transceiver)
- colliders are used on the buildings to tell if I am inside or outside, and to respectively update a parameter which tracks player distance from the doorway while outside or while inside.
- Lots of automation curves change EQ and spatialiser settings to make it sound like the sound is around you while outside, but collapsed to the doorway position while inside.
It’s a bit more complicated than that and could do with refining, but the core of it is still very awkward to use. Some kind of simpler system of achieving the same effect would huge relief and time saver, and if it were easier, hopefully we could see more games be shipped with this kind of feature!
