Hello,
The “ShareSetInside” attribute is used to define which “ReverberationPreset” is used for the plane.
For the Icon A5, this is the same impulse response as the TBM930. But sounds and packages are different between TBM930 and Icon A5.
You can find a list of all available reverbs here :
\Documentation/02-Asset_Creation/Sounds/01-Master_Mixer_Hierarchy.html#game-defined-auxiliary-sends
About the insulation parameters, Insulation_ExitClosed and Insulation_ExitOpen attenuate all the outside sounds. Meaning that all the sounds that are routed in the Outside Busses in the Wwise project (you can find a sample of the Wwise project in the SDK).
For engine sounds, different sounds are used for Inside and Outside viewpoints, and are thus not affected by the Insulation attributes.
