We're testing if Wwise is what we're looking for in our project and for the most part it does, but there's this big issue we ran into. For some reason, when we play the scene we're testing Wwise's features in the timeline, the Ak Event clip disappears. But this only seems to happen if the Event property is currently holding an event. Something similar happens when we enable "Retrigger Event" where the clip vanishes from the timeline but only if the Event property isn't empty.
This issue is urgent since it may greatly hamper our workflow while we figure a way to either solve or circumvent it, or to simply discard Wwise altogether and find a different application, which would be the worst option since it has features that are really convenient to us. It may also be something on our end but we're at an a loss of what it could be. We're currently using Wwise 2019.1.0 as well as the Unity Integration 2018.1.6 in Unity 2018.3.8f.
Thanks for reading and hoping for a hasty answer,
So, it turns out that the clips aren't deleted. Once the event is set, their max duration is automatically set to 0 and it "vanishes" as soon as the timeline updates. You can find it again selecting the track's content (by clicking and dragging) until you find it's exact location in the timeline and then carefully dragging it so that it's visible again, but as soon as you update the timeline again it's duration is set again to 0.
I already answered this to Radek Karnik but just in case I'll put it here too: I made sure the JSON metadata is generating and that it's set to estimate duration. It's been like that since we starting checking out Wwise.
