I’m starting a new Unreal project, and I’m trying to make a more accessible system for sound effects that other designers can use to make small sound adjustments, like volume. Right now, I have a volume curve that can be controlled in blueprints to go from -10db to +10db, which is on a template that I use to make all my events.
If, somewhere down the line, I want to expand it to -20db instead of -10, is there a way that I can change the curve in one place and have it affect every event using that specific parameter, or do I have to copy and paste that curve into every event?
If that isn’t something that FMOD supports, how can I request that feature?
At present, the only properties of events that cannot share automation curves by any means are the event macro controls’ “Pitch,” “Doppler scale,” and “Min & Max Distance” properties.
Automation curves on parameters are shared by every instance of that parameter, so every event that uses that parameter will use the same automation curve. (In fact, it’s more common for people to ask us if there’s a way to not use the same automation for every instance of a parameter.)
There’s a way to make effect properties use the same automation curves, too: If you make an effect a shared effect, every instance of that effect in your project will use the same property values - including automation on those property values, meaning that every instance of a given shared effect also shares the same automation curves.
The only automatable properties that can’t share automation are event properties other than those associated with effects and parameters: Track volume properties and the event macro controls. Even then, you can work around not being able to share automation on volume properties by using gain effects instead, since you can just make the gain effects shared and then use them in multiple events - which sounds like it suits the use-case you mention in your question.
