Best way to dynamically change the reverb level for different rooms?

Question

Hi everyone,

I'm working on a platformer, made in Unity 2017 and in the same vein of games like Little Nightmares and Inside. I'm trying to dynamically change the level of my reverb as the player walks through different ambiances. What would be the easiest and less resource-hungry way to do such thing?

In the Limbo example project I saw that they used one single auxiliary send with a Wwise RoomVerb effect in it, and a RTPC parameter called "Reverb Level" attached to the 'Reverb' output level of the effect. Is this the best way to do it? Does this mean that I will have to sit with the programmer and tell him where and at what rate to change this parameter through the whole map? Is there no more independent way to do this, or maybe I'm still not understanding how the RTPC's work?

In general, I'm still learning how Wwise works. I really like it, but I'm still far from fully understand it.

Thanks in advance.
