This section describes how to setup Reverbs in Levels. In CRYENGINE Reverbs are called Environments.
Setup Reverbs (Environments) in Levels Using the Audio Area Entity
Create an Auxiliary Bus in Wwise and assign an effect to that bus.
Use the Audio Controls Editor (ACE) to connect the Wwise Auxiliary Bus to an ATL Environment. Learn about the ACE here.
Use an Area Shape and AudioAreaEntity or AudioAreaAmbience as described here.
In the AudioAreaEntity or AudioAreaAmbience properties, select as the AudioEnvironmentName the ATL Environment that is connected to the Auxiliary Bus.
Set the EnvironmentDistance. This is the distance in meters from the edge of the assigned Shape where the fading of the Environment (Reverb) begins.
EnvironmentDistance and Rtpc/FadeDistance
After setting the Environment (Reverb) in the AudioAreaEntitiy or AudioAreaAmbience properties the Audio will be sent to the Auxillary in Wwise when approaching the attached Area Shape.
However, for this functionality to work the Game Defined Auxillary Sends in Wwise have to be enabled (they are disabled by default). Enabling this functionality allows you to select which Sounds should be affected by the ATL Environments (Reverbs) and to also adjust (separately) the send volume for each Sound in Wwise.
The Game-Defined Auxiliaries can be found in the general settings of the Sound Property Editor in Wwise.
